Dogwood Tree Won't Bloom: Wrong Sun, Too Much Nitrogen

Two Fixes

Dug-from-woods dogwood in full sun, 5 ft tall, no blooms. Nearby one blooms fine.

1. Move it. Dogwoods are understory trees—they need filtered sun or part shade. Full sun stresses them.
2. Fertilize with LOW nitrogen. High nitrogen = vegetative growth, no flowers. Use a bloom-booster (high P/K) to shift energy to flowering.

Dogwoods are not male/female—all bloom if conditions are right.
