Troubleshooting
Crenate Orchid Cactus problems — and how to fix them
Crenate Orchid Cactus (Epiphyllum crenatum) 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
Usually caused by moving the plant once buds have set, or sudden temperature swings. Keep in a stable spot once buds appear.
Root rot
Overwatering combined with poor drainage. Allow the top portion of soil to dry thoroughly between waterings.
No flowers
Inadequate winter rest is the chief culprit. Reduce water and temperature (10-13°C) for 6-8 weeks from mid-autumn.
Soft, yellowing stems
Can indicate overwatering, root rot, or insufficient light. Check roots and improve drainage and light levels.
Mealybugs
White cottony deposits on stem edges and joints. Remove manually and treat with neem oil or insecticidal soap spray.
