Troubleshooting
Fishbone Cactus problems — and how to fix them
Fishbone Cactus (Epiphyllum anguliger) 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.
No flowers
Needs maturity, bright indirect light, and a cool, drier winter rest to bloom. Provide that rest period and adequate light, and be patient with younger plants.
Scorched or bleached stems
Excess direct sun pales and burns the flat stems. Move to bright indirect light with only gentle early sun.
Root rot / limp stems
Overwatering or heavy soil rots roots and the stems go soft and yellow. Repot into airy mix and water only when the surface dries.
Mealybugs
Cottony pests hide in the stem notches. Dab with 70% isopropyl alcohol on a swab and isolate the plant until the infestation is gone.
