6-12-12 Fertilizer: Complete Guide
Formulated for fruiting vegetables like tomatoes, peppers, and squash, this blend supplies twice the phosphorus and potassium relative to nitrogen. Low 6% nitrogen limits excess foliage, directing energy toward blossoms and fruit. Apply 8 lbs per 1,000 sq ft at transplant and again at flowering. Using it too early during vegetative growth starves young plants of needed nitrogen.
