New task force designed to protect our forests from the impact of the mountain pine beetle in the coming decade, particularly Front Range Ponderosa forests

Governor Jared Polis recently took Executive Action in establishing the creation of a new task force to proactively develop strategies to help protect Colorado's communities, forests, and critical water resources from the impacts of the mountain pine beetle.

Protection from fire is a key focus of the task force, as hotter and drier climate along with weakened trees poses greater risk to forests, waterways, and homes.

"The pine beetle outbreak is just now beginning to emerge in the heavily populated Front Range. Aerial forest health surveys conducted in 2025 by the U.S. Forest Service and Colorado State Forest Service reveal a significant and expanding mountain pine beetle outbreak in Ponderosa pine forests up and down the Front Range, with pockets of brown and beetle-killed trees already visible along the U.S. 285 and I-70 corridors" said the release.

Warmer temperatures, ongoing drought, and the absence of sustained cold periods have weakened trees and created ideal conditions for beetle survival and spread - conditions expected to continue into the next decade.

So far in our area and most of Douglas County, there are very few confirmed reports of mountain pine beetle in trees. This article from CSU, however, mentions elevated levels of infestation starting in October 2025, and provides an excellent map that lets homeowners pinpoint where the outbreaks are occurring (you can even type in your address and see if any mountain pine beetle has been detected near your property).

Black Forest Garden Club is hosting an event on April 11 devoted to trees. This Master Gardener presentation and discussion will address best varieties of trees for our area, diseases and pests, troubleshooting issues, pruning tips, and a lot of time dedicated to Q&A with the audience. 10:30a - 12:30p at Pradera Fire Station.

Growing cold-tolerant Agave in Colorado

2/11/2026

New Mexico Agave is shown in photo above.

Certain hardy, cold-tolerant agave species can grow in Colorado, particularly along the Front Range and in warmer, dry areas.

Success in growing Agave in Colorado depends entirely on choosing the right species to plant.

While not native to the state, species like Parry’s agave, Utah agave, Havard's Agave, and New Mexico "Century Plant" Agave can survive Colorado winters if planted in well-drained soil.

Parry's Agave

Hardy to about -20°F when dry
Compact blue-gray rosettes
Excellent for rock gardens and xeriscapes
One of the most reliable choices here

Utah Agave (most hardy form)

Native to high desert climates
Hardy to around -10°F to -20°F depending on variety
Smaller, very architectural

Havard's Agave (with protection)

Hardy to about -10°F
Large, striking blue rosette
Needs superb drainage

New Mexico Agave

Very cold hardy
Thick succulent silver gray leaves edged with burgundy spines
Drought resistant/drought tolerant

Video on how to plant and cultivate Agave from High Country Gardens is here.

Critical Growing Tips at 6,300 ft

Build a berm or raised bed if you have clay soil (clay soil = rot risk). Plant on a mounded, gravel-heavy mix (at least 50% gravel/pumice).
Full sun with South or West exposure. A heat-reflecting wall is ideal.
Gravel mulch only - no bark. Keep crown dry.
Provide Winter moisture protection to avoid 'winter burn' - this is very important at our elevation (2 to 3 inches of mulch; water deeply in early Fall and then keep them dry from late Fall through early Spring; use protective covers like wrapping plants in burlap or frost covers, or cover with upside down plastic buckets with holes for ventilation to protect from winds).

Avoid These types of Agave species:

Agave americana
Variegated agaves
Any labeled hardy only to zone 7+

Design Pairings That Thrive at our elevation

Blue fescue
Yucca filamentosa
Ice plant (hardy varieties)
Penstemon
Sedum
Hesperaloe (in protected spots)

The Colorado Bluebird Project and why it is so important

2/10/2026

The bluebird carries the sky on his back. - Henry David Thoreau

The Colorado Bluebird Project is a volunteer-driven conservation effort dedicated to increasing populations of native bluebirds across Colorado through nest box monitoring, habitat improvement, and public education.

By installing and maintaining bluebird boxes along carefully managed trails, volunteers help offset habitat loss and provide safe nesting sites for species like the mountain and western bluebird. The project not only supports bird conservation but also connects communities to Colorado’s open spaces and the joy of stewardship.

This volunteer-run project aims to improve the vitality of bluebird populations and to inform and educate Coloradans about bluebirds. From April through August, volunteers of all ages are needed to help monitor the nest boxes.

Click here for detailed information on the Project's goals, functions, volunteer efforts.

Did you know that the Black Forest Garden Club has installed bluebird boxes in Douglas County? You'll see the boxes along the Bayou Gulch Open Space trail in the Two Bridges Trail area.

A conversation with our local fire mitigation expert

2/9/2026

Community Risk Reduction Specialist Colleen Potton has a wealth of knowledge on how to easily and inexpensively reduce the risk of fire around our homes and on our properties.

The most important things to know:

1. Fire can be caused by a number of things like lightning, cigarettes being thrown out a car window, or carelessness with outdoor fires. However, a fire grows and spreads quickly due to embers - those little flying hot things that are easily carried by wind and eventually land somewhere. If that somewhere is in the dry brush underneath your deck or in the bark mulch up against the foundation of your home, it could spell disaster.

2. When something like a shrub or wood pile or porch chair catches fire, the flames typically leap two times as high as the object itself. Whatever is above the object can catch fire because the flames might be able to reach it.

One of our Garden Club members recently asked Colleen come to their house (she visits for free) to provide a risk assessment and learned their property isn't wildfire ready. The siding on the garage side of the home, for example, doesn't come all the way down to the ground on the outside of the structure. This has left a small area between siding and ground that an ember could fly in to and catch the particle board behind the siding on fire. Solution: add metal flashing in that area.

A large Ponderosa pine is too close to the composite deck (composite is better than wood for decking). Solution: cut the tree back and keep all pine needles out of the roof gutters nearby. Also, remove the shrub that is growing directly under the tree.

Homeowner uses rock mulch for everything in the landscape except two small beds that have bark mulch and come right up to the foundation of the house. Colleen advised changing the bark mulch over to rock because of how close it is to the home and also because bark mulch can easily trap embers that can turn into fire, whereas rock mulch helps prevent embers from turning into something bigger.

Are pine needles harmful in the garden?

1/29/2026

Despite the common myth, pine needles do not significantly acidify garden soil.

Using pine needles in the garden is not harmful to soil or plants in Colorado. They make for excellent mulch that helps retain moisture, suppress weeds, and decompose into beneficial organic matter.

Fresh needles are slightly acidic, but they do not lower soil pH to damaging levels in our generally alkaline soils.

What pine needles do to the soil
Pine needles slowly break down and add organic matter to the soil, improving its structure, moisture retention, and drainage much like other natural mulches. Their acidity diminishes as they decompose and most soils have enough buffering capacity to resist major pH change.

As a mulch, pine needles (often called pine straw) suppress weeds, protect roots from temperature swings, and allow water to filter through easily without forming a crust. They’re especially helpful around acid-loving plants like blueberries, hydrangeas, hostas, Colorado Blue Spruce, mountain ash, and some viburnums, but they’re also safe to use around most garden plants and won’t harm them.

While they decompose slowly, they can be added to the compost pile.

IMPORTANT NOTE: Dry, deep layers of pine needs can be highly flammable, so they should be managed carefully near homes. They can also be slippery if used on pathways or walkways.

Meet Wilder - a fun and inspiring resource that gets Colorado's kids outside playing and learning

1/28/2026

Imagine all the good things that would happen if kids ran around and played outside every day.

Today, the average child spends less than seven minutes a day outside in unstructured play (and three+ hours every day in front of some type of screen). As most of us can attest, that's a drastic decrease in outdoor time compared to when we were growing up.

According to Generation Wild, the benefits of playing outside every day are profound: stress and anxiety decrease, creativity and imagination grow, self-reliance flourishes, learning is heightened, physical fitness improves, immune systems get stronger and healthier, and ADHD symptoms are reduced.

Generation Wild is a movement created by Great Outdoors Colorado to "change an entire generation of kids by connecting them to the outdoor world". It began with a list of outdoor activities (100 Things to Do Before You're 12 in both English and Spanish), and has continued to add to their mission with their clever 20 Ideas List designed to get kids (and their parents/grandparents/caregivers) outside for at least 20 minutes a day.

With fun ideas like a color scavenger hunt, easy to make nature fossils, flashlight tag, and set up a toy carwash, the list's ideas provide benefits "as big at the outdoors".

Think kids should spend more than seven minutes a day playing outside? You're not alone. Hundreds or organizations around the state think that too. Check out Generation Wild's partners here. Prepare to be impressed.

If you or someone you know has kids that could benefit from being outdoors more, please share this amazing website with them. Even better, offer to be the one to take them outdoors for some much needed outdoor playtime using one of the many fantastic ideas on the Generation Wild website and library.

Bring Pantone's Cloud Dancer color into your garden this year

1/28/2026

Pantone’s Color of the Year for 2026 is “Cloud Dancer,” a soft, billowy white meant to evoke calm, serenity, and a fresh start.

Pantone’s Color of the Year is an annual selection meant to reflect the global mood, cultural shifts, and emerging trends across design, fashion, art, and society.

Chosen by the company's color experts, it serves as both a creative forecast and a source of inspiration, influencing everything from product design and interiors to branding and marketing to worldwide.

Landscape plants that evoke Cloud Dancer will have clean white blooms, silvery foliage, or a light, floating habit that feels calm and luminous. Think of plants that read as gentle and atmospheric rather than stark.

Find inspiration in the 'Cloud Dancer' color with this selection of plants:

White-blooming standouts

White hydrangeas (like ‘Limelight’ or ‘Annabelle’) for billowy, cloud-like masses
Shasta daisy and white coneflower for classic, fresh brightness
White roses (try Snowdrift, Blanc Double de Coubert Rugosa, Alba Rugosa, White Out (Knock Out Family), Polstjarnan (climber), White Dawn (climber)
Gaura (white varieties) for an airy, drifting effect
White Peonies - crepey and delicate petals on this pretty and popular variety
Candytuft - masses of airy white blooms perfect for groundcover
Virginal Mock Orange - fluffy double flowers on arching branches (native mock orange has single flowers, equally beautiful)
White Cosmos - tall and flowy and carefree

Silvery and pale foliage

Lamb’s ear (Stachys) with its velvety, pale leaves
Dusty miller and artemisia for cool, misty tones
Silver sage and Russian sage for light-reflective structure

Soft grasses and accents

Feather reed grass (light cultivars)
Mexican feather grass for movement and haze
White tulips, alliums, dahlias, and snowdrops

Any of these plants will contribute to a landscape that feels quiet, and breathable — a lovely interpretation of Cloud Dancer’s serene, weightless character.

Tips for using a heat map for seed starting

1/26/2026

A heat mat under seed starting trays can grow healthier plant starts for your garden, but using it incorrectly can spell disaster for tender seedlings.

It won't be long before it is seed starting season!

Using a seed heat mat properly can make a huge difference in seed germination speed and success. Seed starting indoors is an excellent way to get a jump on the normally short gardening season here in Colorado.

Here’s what to know about using heated mats under your seed starting trays:

1. Place the mat under the tray, not over it
Set the heat mat on a flat, dry surface and place your seed tray directly on top. Heat should warm the soil from below, mimicking natural spring conditions.

2. Pair it with a thermostat (best practice)
Many heat mats can run warmer than needed. A thermostat keeps soil temperatures in the ideal range—usually 65–75°F for most seeds, and 75–85°F for warm-season crops like peppers, tomatoes, and eggplant.

3. Monitor soil temperature, not air temperature
Use a soil thermometer pushed into the mix. The goal is warm soil; the surrounding air can stay cooler.

4. Keep soil evenly moist
Heat increases evaporation, so check moisture daily. Water from the bottom when possible to avoid damping-off disease.

5. Remove heat after germination
Once most seeds sprout, turn off the mat. Continued bottom heat can lead to weak, leggy seedlings. At that point, bright light is more important than warmth.

6. Use only during germination
Seed heat mats are for starting seeds—not for long-term growing. Think of them as a jump-start, not a constant heater.

Bonus tips:

Use a humidity dome only until seeds emerge
Elevate trays slightly for airflow if overheating occurs
Clean mats between uses to prevent disease

Used correctly, a heat mat can shave days off germination time and give your seedlings a strong, even start.

You can make pickles any time of year with these cucumbers

1/26/2026

One of the best cucumbers for sliced pickles are available all year - here's why they're great for winter pickling

English cucumbers are great for pickles because they have thin skins, small seeds, and firm flesh, which means they stay crisp and don’t need peeling or seeding. Their mild flavor absorbs brine well, giving you a clean, balanced pickle without bitterness.

And they're available in grocery stores year-round.

They’re also uniform in size and low in water content compared to some slicing cucumbers, so they pickle evenly and hold their shape nicely—especially for refrigerator pickles and quick pickles.

English cucumbers are wrapped in plastic to protect their thin, delicate skin and extend shelf life. Unlike waxed slicing cucumbers, English cucumbers aren’t coated, so the plastic wrap helps prevent moisture loss, bruising, and shriveling during transport and storage.

The wrap also reduces exposure to ethylene gas from nearby fruits, which can cause cucumbers to yellow and soften more quickly. While it does create extra packaging, it significantly cuts food waste by keeping the cucumbers crisp and fresh longer.

The thin plastic shrink-wrap on English cucumbers is generally not recyclable in curbside recycling bins in Colorado. This type of plastic is considered "film plastic," which tangles in sorting machinery.

Here is how to recycle the English cucumber plastic in Colorado:

Store Drop-off: You can often recycle this film at specialized drop-off locations, such as the front of many grocery stores including King Soopers, Sprouts, and Safeway - look for the bins near the front of the stores).
Keep it Out of Blue Bins: Do not place the plastic wrap in your regular curbside recycling cart.
Preparation: Ensure the plastic is clean and dry before taking it to a drop-off location.
Consider trying Ridwell - an amazing company that makes it simple to recycle stuff you can't recycle curbside (like multi-layer plastic, prescription bottles, plastic lids, metal lids, film plastic, plastic bread tags, styrofoam and much more) through their twice monthly pickup service. Only $18 per month and so very good for the planet!

Good news: Some newer, sustainable packaging alternatives (like paper wrap) are being introduced to the market and we're hoping to see them on produce in place of plastic soon!

Easiest DIY bird feeder (and it's free and compostable!)

1/19/2026

You'll need only three items for this easy eco-friendly winter craft

Birds that haven't migrated south for winter can benefit from an extra food source, especially during winter's most harsh weather.

Here's an eco-friendly orange peel bird feeder that will take only minutes to craft.

What you'll need (makes two bird feeders)
1 orange (more if you want to make multiple bird feeders)
Twine or sturdy string
Bird Food

How to make
Cut orange in half. Scoop out the contents of both halves. Poke four to six holes around the rim of the orange (about a half inch below the rim). Tie twine or string through each hole and bring the pieces of twine together at the top, tying them in a single loop. Make the twine as long as you want - this will be what hangs the feeder (make sure feeder is well off the ground so larger animals can't reach it). Fill with bird seed, hang from a tree branch. Check it every few days to make sure it is still has seeds and is clean (if it has bird poop take it down and throw it on the compost pile minus the twine which can be reused for the next time you make a bird feeder like this).

Tasty microgreens to grow indoors this winter (and all year)

1/16/2026

Microgreens are fast and easy to grow indoors and provide a plethora of nutrients

Some of the most flavorful and easy microgreens for indoor growing include radish, broccoli, and pea shoots.

Radish microgreens are fast and ready in just 5 to 7 days with a crisp, peppery bite that livens up salads and sandwiches.
Broccoli microgreens have a mild, fresh flavor and are popular for both taste and nutrition.

Pea shoots are slightly sweet, tender, and great in wraps, stir-fries, or simply snipped onto a plate as a garnish.

For more variety, try sunflower, arugula, and mustard microgreens.

Sunflower greens are nutty and crunchy, making them especially satisfying. Arugula brings a bold, spicy kick similar to the mature leaf.
Mustard microgreens range from mildly tangy to quite hot, depending on the variety.

Other popular microgreens to try:
Kale
Lentils
Red-veined Sorrel
Beets
Chives
Curled Cress
Basil
Marigold

All of these grow well on a sunny windowsill or under a simple grow light, need minimal space, and reward you with fresh flavor year-round.

How to Sow and Grow Microgreens Indoors

Choose a shallow container and soil
Use a tray or shallow container with drainage holes. Fill it with 1 to 2 inches of a light potting mix or seed-starting mix. Gently level and lightly moisten the soil before sowing.
Sow seeds densely
Sprinkle seeds evenly over the soil surface. Microgreens are grown close together, so spacing is not critical, just avoid large piles. Lightly press seeds into the soil. Cover only if the variety needs darkness to germinate, such as peas or sunflowers.
Water gently
Mist the surface or water from the bottom by setting the tray in a shallow pan of water until the soil is moist. This prevents seeds from washing away.
Cover and germinate
Place a humidity dome, another tray, or a loose cover over the seeds for the first 2 to 4 days. Even a clear plastic bag tied tightly will work. Keep them in a warm spot. Check daily and remove the cover as soon as seedlings emerge.
Provide light
Move trays to a bright windowsill or under a grow light for at least 6-8 hours a day (more is better). Adequate light keeps microgreens short, sturdy, and flavorful.
Maintain moisture
Keep soil evenly moist but not soggy. Bottom watering works best once seedlings are up to reduce mold risk. Because we live in such a dry climate, it is a good idea to mist the seeds daily.
Harvest
Most microgreens are ready in 7 to 14 days (sometimes even less), when they are 2 to 4 inches tall and have their first true leaves. Use clean scissors to cut just above the soil line.

Helpful tips:

Use clean trays and fresh soil to prevent mold
Improve air circulation with a small fan if needed
Harvest just before eating for best flavor and nutrition
Find microgreens seeds at your local plant nursery in the seeds section, or order from Johnny's Selected Seeds.

Microgreens are nutrient-dense with high concentrations of vitamins, minerals, and antioxidants. They are especially rich in vitamins C, E, and K, and have beneficial plant compounds that support overall health.

Dispose of old potting soil or save it for Spring?

1/16/2026

Fresh potting soil provides the medium in which plants will grow roots. Make sure your container potting soil is up to snuff.

As you begin your yearly home and garage decluttering in preparation for Spring, don't toss that partial bag of last year's potting soil.

Potting soil is the primary supplier of nutrients to annuals and perennials planted in the confines of an outdoor container. In most cases, potting soil in pots is worth saving rather than tossing in Fall.

If the mix still drains well, smells fresh, and isn’t riddled with roots or pests, it can be reused next season (but it will need a refresh).

Start by pulling out old roots and debris, then loosen the soil and amend it with two to three inches of rich compost and 50% fresh potting soil to replace nutrients that were used up. Till in well to help restore structure and aeration.

Potting soil that has been stored dry and protected from rain and snow can be used in Spring plantings, especially for annuals and non-fussy container plants.

That said, there are times when it’s best to let potting soil go. If container plants struggled with disease, insect infestations, or persistent fungus gnats, reusing that soil risks carrying problems into Spring. Best to dispose of it.

Soil that has become compacted, waterlogged, or salty from heavy fertilizer use is another candidate for disposal.

A simple rule of thumb: if the soil supported healthy growth last season and still looks and smells good, save it and amend it as noted above. If not, compost it or spread it thinly in the landscape and start fresh in spring.

2026 Plant of the Year - we can grow it!

1/9/2026

Deer-resistant perennial; it represents joy and prosperity.

1-800-Flowers has designated their 2026 Flower of the Year. The flower and plant of the year are chosen based on their symbolic meaning, as well as consumer and floral trends. This year's flower is intended to represent positive feelings and futures.

Delphiniums are beloved for their tall, elegant spires of flowers that bring a sense of drama and vertical interest to the garden. Blooming in shades of blue, purple, pink, and white, they are a classic choice for cottage and perennial borders, where their height makes them natural backdrops for shorter plants.

Their intricate, hooded blossoms are especially striking in early summer and are often associated with traditional, romantic garden designs.

They prefer full sun, rich soil, and consistent moisture, and their tall stems often need staking to protect them from wind. With proper siting and care, delphiniums can return year after year, offering a spectacular display that few other perennials can match.

Colorado Considerations

Heat: Provide afternoon shade to help them thrive in hot, dry conditions.
Wind: Sheltered spots are crucial for protecting tall spikes.
Water: Mulch and consistent watering are essential for Colorado's arid climate.
Deer usually avoid them for tastier treats like hostas; however, they aren't entirely deer-proof, especially when new growth emerges in spring, and deer might nibble if hungry, but significant damage is rare.

Easy herbs to grow indoors

12/31/2025

No need to purchase expensive grocery store herbs when you can easily grow your own indoors!

Growing herbs indoors is one of the easiest and most satisfying ways to keep fresh flavor close at hand. Here’s a simple, low-stress approach that works well for beginners and busy gardeners alike.

1. Start with easy herbs (some herbs adapt to indoor conditions better than others). The most forgiving choices are:

Basil
Chives
Mint (best grown alone)
Parsley
Oregano
Thyme
Rosemary (needs the brightest light)

2. Give them enough light. Light is the #1 challenge indoors.

Place herbs in a south- or west-facing window if possible.
Herbs need 6–8 hours of bright light daily.
If window light is weak or winter days are short, a simple LED grow light 6–12 inches above plants makes growing almost foolproof.

3. Use the right pots and soil

Choose pots with drainage holes (this matters more than size).
Use a lightweight potting mix, not garden soil.
Terracotta is great for herbs that prefer drier soil (thyme, oregano, rosemary).

4. Water carefully. Overwatering is the most common mistake.

Water when the top inch of soil feels dry.
Empty saucers after watering. Herbs prefer slightly dry roots over constantly wet ones.

5. Keep them comfortable

Average indoor temperatures (65–75°F) are perfect.
Avoid cold drafts and heat vents.
Normal household humidity is fine; just don’t let leaves touch cold glass.

6. Feed lightly

Use a diluted liquid fertilizer about once a month.
Too much fertilizer causes lots of leaves but weak flavor.

7. Harvest often (this helps!)

Trim herbs regularly to keep them bushy.
Never remove more than ⅓ of the plant at one time.
Pinch basil above a leaf pair to prevent legginess.

8. Start smart

Young nursery plants are easier than seeds for beginners.
If growing from seed you'll need to be patient — most herbs grow slowly at first.

Here's an article with details for growing the herbs mentioned above.

The best way to dust plant leaves

12/31/2025

Dusting indoor plant leaves is a small task that makes a big difference in plant health. Clean leaves photosynthesize better, resist pests, and simply look happier.

Dust on plant leaves blocks light and clogs leaf pores, reducing photosynthesis and air exchange. Regular cleaning keeps plants healthier and more vibrant.

Simple, Safe Ways to Dust Leaves
1. Soft cloth method (best for most plants)

Use a clean, damp microfiber cloth or soft cotton cloth. Rinse the cloth often so you’re not redistributing dust.
Support the leaf from underneath with one hand and with the other hand gently wipe from base to tip.

2. Shower rinse (great for sturdy plants)

Place plants in the sink or shower and gently spray with lukewarm water.
Let plants drain completely before returning them to their spot.

3. Soft brush for fuzzy or delicate leaves

Plants like African violets or begonias dislike wet leaves. For these types of plants, use a dry, soft paintbrush or makeup brush to lightly sweep dust away.

What to Avoid

Cold water — it can shock tropical plants.
Use leaf shine products (commercial or homemade) with caution as they can clog pores and actually attract dust. A damp cloth is usually all that is needed.

If you want to try cleaning plant leaves with a solution, try one of these recipes on a leaf or two to gauge how well it works for that specific plant:

Mild Soap & Water: Mix a few drops of mild dish soap with water in a spray bottle, spray lightly, then wipe with a damp cloth.
Vinegar & Water: Combine 1 teaspoon of vinegar with 2 cups of water to create a shine-enhancing, pest-repelling solution.
Lemon Juice & Water: Use equal parts lemon juice and water for shine, especially good for hard water spots.
Milk & Water: A 1:1 mix of milk and water creates a gentle cleaner that leaves a soft sheen.

How Often Should You Dust?

Light dusting: every 2–4 weeks. More often if you have pets, open windows, or forced-air heating.

Bonus Tip
While dusting, inspect leaves (especially undersides) for early signs of pests like spider mites or scale. Catching issues early and resolving them is one of the best gifts you can give your plants.

Tips for fuller, healthier indoor potted plants during their natural winter dormancy period

12/31/2025

Many indoor plants have a form of dormancy, though it’s usually gentler and less obvious than for outdoor plants.

Houseplants slow their growth in fall and winter because of shorter days and lower light levels. Plants may stop putting out new leaves, grow more slowly, or seem “paused.” This is a natural rest period and not a problem.

To get a fuller, healthier indoor potted plant, focus on encouraging balanced growth above and below the soil line. A few consistent habits make a big difference:

Light Is Everything

Place plants in bright, appropriate light for their type — most indoor plants want bright, indirect light.
Rotate pots every week or two so growth stays even and doesn’t lean toward the window. If plants look leggy, they’re usually asking for more light, not more water.

Water With Intention

Water less, letting soil dry more between waterings. Roots need moisture AND oxygen to thrive.
Avoid frequent, shallow watering; deep watering encourages stronger root systems.
Always match watering to the plant’s needs (succulents vs. tropicals).

Prune and Pinch

Regularly pinch back tips or prune leggy stems just above a leaf node. This signals the plant to branch, creating a fuller shape. Healthy plants will respond with bushier growth.

Feed, But Gently

Overfeeding causes weak, floppy growth, so go easy on fertilizer during this time. Resume feeding in spring, and remember that less is more even then.

Air, Humidity & Cleanliness

Good air circulation helps prevent pests and disease.
Many houseplants enjoy higher humidity — group plants together or use a pebble tray if your home is dry.
Wipe dust from leaves so plants can photosynthesize efficiently. Learn the best way to dust, and recipes for restoring nice, shiny plant leaves here.

Bonus Tip
Combine plants of the same type in one container for an instant fuller look, or root pruned cuttings and replant them in the same pot as the host plant — gardeners’ favorite trick for lush, layered looking indoor plants.

When days lengthen in late winter or early spring, most houseplants naturally wake up and resume growth. At that point, you can increase watering, resume feeding, and prune or repot if needed.

Indoor plants do rest—it’s their way of conserving energy. Respecting that rhythm is one of the best ways to keep them healthy and lush year after year.

Tips for winter houseplant care

12/19/2025

Winter can be challenging for houseplants, but a few adjustments will keep them healthy until spring.

With a little extra attention, your houseplants will rest comfortably through winter and be ready to grow again when days lengthen.

Water less often: Most houseplants grow more slowly in winter, so let the top inch or two of soil dry out before watering to prevent root rot.
Maximize light: Short days mean less sunlight; move plants closer to bright windows and rotate them regularly for even growth.
Increase humidity: Dry indoor air can stress plants; use a humidifier, group plants together, or place pots on trays filled with pebbles and water.
Skip fertilizer: Hold off on feeding until spring, when active growth resumes.
Watch for drafts and heat: Keep plants away from cold windows, doors, and heating vents, which can cause leaf drop or browning.
Clean and inspect: Wipe dust from leaves so plants can photosynthesize efficiently, and check regularly for pests that thrive indoors during winter.
Save repotting until Spring: Plants are stressed if their roots disturbed during dormancy. If you don’t want leaves dropping, drooping or changing color, leave your plants in their current homes (even if they’re root-bound) until spring returns and growth resumes.
Minimize drafts: Keep houseplants away from exterior doors, leaky windows, fireplaces and heat registers so they don’t stress and then drop their leaves or turn yellow or brown.
Trim yellow leaves and check for pests: Tending to plant leaves all year is a good practice to keep your indoor plants healthy. Use a pair of clean, sharp pruners to remove any yellow or brown leaves, which are often signs of watering issues, temperature fluctuations, fungal infection, or pests. Don’t remove more than 20 percent of the leaves.
Treat diseased plants: most pests can be eliminated with Neem oil or insecticidal soap (DIY recipe below). Repeat as necessary). Isolate sick plants from healthy ones so the problem doesn’t spread. If you don’t know which treatment to try, ask the indoor plants experts at your local plant nursery.

DIY Insecticide Soap
Use Murphy's Oil Soap ($4 for 32 ounces at Target) to make your own DIY insecticidal soap spray.

Murphy's Oil Soap Insecticide Basic Recipe for Plants

Per Gallon: 1 Tablespoon Murphy's Oil Soap + 1 Gallon Water
Per Quart: 2-3 Tablespoons Murphy's Oil Soap + 1 Quart Water

How to Use Murphy Oil Soap Insecticide

Mix: Combine Murphy's Oil Soap and room-temperature water in a spray bottle and shake well.
Water Affected Plant First: Water the plant the day before spraying.
Apply: Spray the entire plant, ensuring you cover the tops and bottoms of leaves where pests hide.
Timing: Apply on a dry, calm day when temperatures are below 90°F and the sun isn't intense.
Test: Always test on a small area of the plant first and wait 24-48 hours to check for damage.

Tips & Variations

For Whiteflies/Mildew (Stronger): Add 1 tablespoon of canola oil to the gallon mixture for added effectiveness.
Avoid Detergents: Harsh dish detergents can strip protective coatings from leaves, potentially harming the plant. Murphy's Oil Soap is gentle on plants.

For spider mites and other insects affecting cactus and succulents (according to the Cactus and Succulent Society of America): 2 tablespoons of Murphy's Oil Soap to 32oz of water.

How to Winter Water - VERY important!

12/19/2025

Don’t count on Mother Nature and the hope of a big snow to get your trees and perennials through the winter this year.

Snowfall usually provides far less moisture than rain, and we don't have to tell you that we're in a particularly concerning dry spell right now, so you’ll want to supplement with some winter watering for your trees, shrubs, and perennials.

Water long enough so that the soil is thoroughly soaked without run-off. Be sure to water areas in high sun exposure which tend to suffer winter kill.

Water your sloped areas using cycle-and-soak: several shorter periods of watering to let the moisture soak in without running off. Dry winter conditions can also attract turf mites, but proper watering can deter them.

If you aren't able to hand-water your landscape this winter, hire a landscape pro to do the work for you. It's a good investment in the long-term value of your property.

Keep watering even after the system is winterized. Don’t water when a hard freeze is expected to save damage to your plants.

In dry winters, all shrubs benefit from winter watering from October through March. Apply 5 gallons two times per month for a newly planted shrub. Small established shrubs (less than 3 feet tall) should receive 5 gallons monthly. Large established shrubs (more than 6 feet) require 18 gallons on a monthly basis.

Trees: In Colorado during winter, you should water trees with about 10 gallons of water for each inch of tree trunk diameter, typically watering once or twice a month during dry spells. Apply water to the "drip line" which is the area directly under the tree's branches (not trunk) where most roots are located.

More Tips

Water when the ground isn’t frozen
Winter watering is only effective when soil temperatures are above freezing. Choose a mild day (above 40°F) so water can soak in and reach roots instead of freezing on the surface.
Trees and shrubs need it most
Established trees, shrubs, and evergreens are especially vulnerable to winter desiccation. Evergreens continue to lose moisture through their needles all winter and benefit greatly from periodic deep watering.
Water deeply but infrequently
Aim for a slow, deep soak every three weeks during dry periods with no snow cover. This encourages roots to stay hydrated without creating ice problems.
Midday is the safest time
Water late morning to early afternoon so moisture can absorb before temperatures drop again in the evening, reducing the risk of ice damage on walkways and plants.
Mulch makes winter watering more effective
A 2–4 inch layer of mulch helps soil retain moisture, moderates temperature swings, and protects roots, making each winter watering more beneficial.

Done correctly, winter watering can prevent browning, dieback, and even plant loss — making it one of the most important (and often overlooked) garden tasks in Colorado.

What happens to trees and shrubs in a very dry winter?

12/19/2025

The damage usually shows up as browned needles and leaves, dead branch tips, delayed leaf-out, or even dieback.

Anatomy of a tree during too-dry Winters
During dry spells, a tree’s anatomy works overtime to conserve water and survive stress. The roots are the first line of defense, stretching outward and downward in search of moisture; fine feeder roots absorb water, but they can die back quickly if soil stays dry, reducing the tree’s ability to hydrate itself.

Inside the trunk and branches, xylem vessels act like tiny pipelines, moving water from roots to leaves, but prolonged dryness can introduce air bubbles that interrupt this flow, a process known as cavitation.

Above ground, the leaves or needles respond by closing microscopic pores called stomata to reduce water loss, which also slows photosynthesis and growth. The bark helps limit moisture loss and protect internal tissues, but during extreme drought even this barrier can’t prevent dehydration.

Together, these systems shift the tree into survival mode, prioritizing water conservation over growth until moisture returns and normal function can resume.

When winter is too dry, a tree can suffer from desiccation, which means it loses more moisture than it can replace. Even while dormant, trees continue to lose water through their bark and, in the case of evergreens, through their needles.

In dry winter conditions — especially with wind and sun — the soil lacks moisture, leaving roots unable to take up enough water. This imbalance causes tissues to dry out, leading to stress that often isn’t visible until spring.

Evergreens are especially vulnerable, but deciduous trees can also be affected, showing weak growth, shedding or scorching of needles, or increased susceptibility to pests and disease.

Prolonged winter drought also reduces a tree’s overall vigor, making it harder to recover when the growing season begins.

Regular winter watering, mulching, and protection from wind can help prevent this type of stress.

Pro Tip: Use an anti-desiccation spray to protect plant foliage (especially evergreens) from 'winter burn' (desiccation). This spray seals water in leaves and needles when roots can't absorb moisture from the ground. Apply immediately!
