Phalaenopsis Not Blooming for Two Years? Florida Grower's Reblooming Guide

Identifying the Problem

Two Phalaenopsis from Lowe's, two years without blooms despite healthy foliage. The grower in Titusville, Florida has them in a west window—adequate but not optimal.

Optimizing for Rebloom

Light: East or south windows are better. South needs afternoon shade; east is ideal. Light breezes help.

Temperature Trigger: In early fall, expose to 55°F nights for several weeks to initiate spike formation.

Fertilizer Switch: During this cool period, replace fertilizer with 1 tablespoon Epsom salt (magnesium sulfate) per gallon of water.

Water & Feed: Water when mix is barely moist. Use balanced orchid fertilizer at 1/4 strength.

Patience Required

Spike emergence may not occur until late fall, with blooms several months later. Florida's humidity is perfect—just manage the temperature trigger and light.
