Fertilizer Burn on Vegetable Seedlings: Too Much, Too Close

Why Your Seedlings Wilted After Fertilizing

Applying a teaspoon of 10-10-10 fertilizer per plant—especially close to the stem of small seedlings—is a classic case of fertilizer burn. The high salt concentration draws water out of tender roots, causing wilting and death.

Correct Fertilizing Practice

1. Wait until seedlings show some growth (first true leaves).
2. Sprinkle a teaspoon of fertilizer in a ring 4 inches from the stem.
3. Water thoroughly to dissolve and move nutrients into the root zone gradually.

Better yet, use a half-strength liquid fertilizer weekly after establishment. Slow-release organic fertilizers (like composted manure or cottonseed meal) are gentler and less likely to burn.
