Troubleshooting
Hooker's Orchid Cactus problems — and how to fix them
Hooker's Orchid Cactus (Epiphyllum hookeri) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bud drop
Moving the plant once buds form, or exposing it to cold draughts, causes bud drop. Keep the plant in a stable, draught-free position from bud set until flowering.
Failure to flower
Without a 6-8 week cool, dry winter rest at 10-13°C, the plant rarely sets buds. Reduce water and temperature from mid-autumn.
Root rot
Caused by overwatering or heavy soil; ensure free drainage and allow partial drying between waterings.
Stem corking
Browning and hardening at stem bases is natural in mature plants but can accelerate with excess moisture. Normal if confined to the oldest growth.
Scale insects
Flat brown bumps along stem edges. Scrape off manually and treat with neem oil.
