Why Broccoli Grows Leaves But No Heads: Phosphorus Deficiency

Introduction

Leafy broccoli with no heads by mid-summer indicates nutrient imbalance.

High nitrogen (lush leaves) with low phosphorus (no buds). Broccoli needs phosphorus for heading.

Spray with bloom-booster or tomato fertilizer (high P) like Miracle-Gro Bloom or Tomato formula.

Add compost, peat, aged manure to balance pH, improve fertility, and prevent disease.

Spray high-phosphorus fertilizer now; amend soil organically for next season's success.
