Using Bloom Booster Fertilizer for Orchids in Cool Conditions

Bloom Booster for Phalaenopsis and Cattleyas

Angelo in Orlando keeps orchids in a garage with indirect sun, temperatures 75°F high / 50°F low. He waters weekly with 20-20-20 but hasn't seen spikes. He asks if he should switch to a bloom booster like Better-Gro 11-35-15, and what outdoor low temperature is safe for moving them to the porch (he thinks 55-60°F).

Expert Response

Good to hear from you, Angelo. Try a bloom booster—whether it actually initiates buds is debated, but it can't hurt and may improve flower color. Consider supplemental lighting in the garage. Yes, wait until lows are 55°F or higher before moving them outside.
