Schlumbergera 'White Christmas' problems — and how to fix them
Schlumbergera 'White Christmas' (Schlumbergera truncata 'White Christmas') 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 before flowering
Caused by sudden changes in light, temperature, or watering, or by dry air. Keep conditions stable once buds form and maintain humidity to hold the buds.
Failure to bloom
Needs cool nights (around 12-15°C) and roughly 13-14 hours of uninterrupted darkness for about six weeks in autumn to set buds. Provide that short-day, cool period and avoid night-time artificial light.
Limp, wilting or rotting segments
Usually overwatering and poor drainage causing root rot. Repot into free-draining mix and let the surface dry between waterings.
Reddish or scorched stem segments
Too much direct sun. Move to bright indirect light; new growth returns to healthy green.
