Plant health will be noticeably improved throughout the growing season if you add a nitrogen boost to your soil this Spring
Adding nitrogen to soil in spring is one of the most effective ways to support strong, healthy plant growth.
Nitrogen fuels leafy development and rich green color by helping plants produce chlorophyll, which is essential for photosynthesis. As plants come out of dormancy in spring, their demand for nitrogen increases, making this the ideal time to replenish what may have been lost over winter. Seeds and seedlings also benefit from early application of nitrogen to the soil before planting (just don't overdo).
Good sources of nitrogen boost for plants includes blood meal (12-15% nitrogen fast acting) or fish emulsion (5-6% nitrogen also fast acting). Use compost, aged manure, manure tea - our recipe is here, feather meal, or alfalfa meal for sustained, long-term release.
For Spring soil prepping, mix nitrogen fertilizer into the top 1-2 inches of soil rather than leaving it on top. Water after application to help nutrients reach the root zone, and consider splitting applications over time to maintain steady growth throughout the season.
Be careful not to over-apply, as too much nitrogen can lead to lush foliage at the expense of flowers and fruit. And don't use too much nitrogen on tomatoes, peppers, squash, and beans, as they don't need as much nitrogen once established.
Vegetable crops that benefit from a nitrogen boost include:
Important note: Nitrogen fertilizer typically lasts in the soil for 2 to 8 weeks for quick-release formulas and 2 to 5 months for slow-release formulations. The longevity depends on soil type (sandy soils leach nitrogen more quickly than clay soils), temperature (nitrogen turns to a gas in high temperatures causing it to escape into the atmosphere), and moisture (heavy rainfall or excessive irrigation can wash nitrogen away).

Vegetable crops that benefit from a nitrogen boost include:
- lettuce
- spinach
- kale
- Swiss chard
- arugula
- broccoli
- cabbage
- cauliflower
- Brussels sprouts
- corn (heavy feeder that needs consistent nitrogen for strong stalks and ear development)
- onions
- garlic
- leeks
- herbs - basil, parsley, and cilantro

Tip: Apply nitrogen early in the growing season and taper off as plants begin flowering or forming fruit to keep growth balanced and productive.
