Overfertilizing with Nitrogen
While zucchini loves nutrients, too much nitrogen turns foliage into a lush green jungle—and delays flowering and fruiting. I giddily added extra compost tea each week, resulting in robust vines that stubbornly refused to bloom!
Stick to a balanced fertilizer (e.g., 10-10-10) applied at planting and again when flowers form. This ensures steady growth without the vegetative excess—your plants will focus on making tasty squash instead of endless leaves.
