Orssich's Holiday Cactus problems — and how to fix them
Orssich's Holiday Cactus (Schlumbergera orssichiana) 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
The most frustrating problem; caused by moving the plant, drafts, dry air, inconsistent watering, or sudden temperature changes after buds form. Keep conditions stable from bud set to flowering.
Failure to bud
Requires at least 12-14 hours of uninterrupted darkness per night and cooler temperatures (10-15°C) for 4-6 weeks from early September. Artificial light at night disrupts this critical rest.
Stem segment yellowing
Usually caused by overwatering, root rot, or excess direct sun. Check drainage and soil moisture, and adjust positioning.
Root rot
Caused by waterlogged compost or a pot without drainage holes. Repot into fresh well-draining mix immediately if the base of the plant feels soft.
Mealybugs
White woolly clusters at segment joints. Treat with isopropyl alcohol on a cotton swab and follow up with neem oil if the infestation is widespread.
