These mini greenhouses are great for herbs
Creating a mason jar greenhouse for growing herbs is a fun and eco-friendly DIY project.
Mason jars are excellent containers for small-scale herb gardening as they provide a clear, compact, and attractive growing environment.
Create a charming mason jar greenhouse to grow your favorite herbs right on your windowsill. It's a great way to add fresh, homegrown herbs to your culinary creations while also adding a touch of greenery to your home decor. Great as gifts!
Here's a step-by-step guide on how to make a mason jar herb greenhouse:
Materials you'll need
- Mason jars with lids
- Herb seeds or small herb plants
- Potting soil or seed-starting mix
- Small rocks or pebbles (for drainage)
- Activated charcoal (optional, for water filtration)
- Herb labels (optional)
- Watering can or spray bottle
- Sunlight or grow lights
Select Your Herbs - choose the herbs you want to grow (popular choices include basil, parsley, mint, thyme, and oregano). You can either start herbs from seeds or purchase small herb plants from a nursery.
Prepare Your Mason Jars - clean your mason jars thoroughly, removing any labels and ensuring they are dry. You can use jars of various sizes depending on your available space and the herbs you want to grow.
Create Drainage Layer - place a layer of small rocks or pebbles at the bottom of the mason jar. This helps with drainage, preventing root rot. If you want to further improve drainage, add a thin layer of activated charcoal on top of the rocks.
Add Potting Soil - Fill the jar about two-thirds full with potting soil or seed-starting mix. Make sure the soil is slightly moist, but not soggy.
Plant Your Herb Seeds (or herb plants if you purchased plants from a nursery) - carefully plant your herb seeds or small herb plants into the soil, following the recommended planting depth (one per jar). Use your finger to create holes for the seeds or plants.
Water Your Herbs - water the soil lightly, making sure it is evenly moist. Don't over-water - a little less is more in this case. You can use a watering can or a spray bottle to avoid over-watering.
Label Your Herbs - if you're growing multiple herbs in different jars, consider labeling each jar with the name of the herb and the date of planting. This helps you keep track of your herbs.
Assemble the Mini Greenhouse - place the mason jar lid on the jar without sealing it tightly. This lid will act as a mini greenhouse cover, creating a controlled environment for your herbs. It will trap moisture, allowing the herbs to thrive.
Provide Adequate Light - herbs need plenty of light to grow. Place your mason jar greenhouse on a sunny windowsill or use grow lights if natural light is limited. Herbs typically require 6-8 hours of sunlight each day.
Care and Maintenance - monitor your herbs regularly for moisture and growth. Water only when the soil feels slightly dry to the touch. Keep an eye out for any signs of pests or disease and address them promptly.
Harvest Your Herbs - once your herbs have grown to a sufficient size, you can start harvesting them by snipping off leaves or stems as needed. Be sure not to take more than one-third of the plant at a time to allow it to continue growing.
BONUS CLEVER IDEA: Another way to grow herbs and seedlings is by using a simple 'hydroponic mason jar connector' kit. This inexpensive connector screws two mason jars together to create the high humidity environment that plants and seedlings love. Instructions for how to are in the link provided.
