Janice, I feed mine weekly with BetterGro 20-14-13 (3/4 tsp per gal.) except for the cool/dry period. Once the sheaths start to swell and watering picks up I give it BetterGro bloom booster 11-35-15 once a month. Saw Ursula's post on the size of her's. My tallest leaf tip is barely six inches. Then again, Ursula grows atomic orchids.
