Bought Dendrobiums, Phalaenopsis, Cymbidiums at Santa Barbara show. All indoors, indirect light, weekly water. Blooms dropping fast, leaves wilting. Cymbidiums (5–9 yrs) told to soak 30 min weekly. Phals/Dends not reblooming. What's wrong?
Fruit gas kills flowers/buds instantly.
Sniff pots—sour smell = broken-down mix. Repot ALL in fresh orchid mix.
Indoors only for bloom display. After flowers, move out. Soaking weekly indoors = too wet. Water by pot weight (light = dry). Cym blooms last 2 months usually.
Early fall: 55°F nights + Epsom salts (1 tbsp/gal, 3x) to trigger spikes for next year.
New growth starting = perfect repot time.
