Christmas Cactus Not Blooming: Light, Temp, Soil Fixes

Year-old Christmas cactus (Schlumbergera) bloomed once, never again. Repotted in poor-draining cactus mix.

Bloom Triggers

• Short days + cool nights (fall).
• Outdoor summer (shade, until nights <40°F/4°C) = best trigger.
• Indoor alternative: 12 hrs total darkness (8pm–8am) from Sept. Double black bags if needed.

Soil Fix

• Fork soil surface before watering (breaks tension).
• Or 1 drop dish soap in water (reduces tension).
• Better: repot in proper gritty mix.

Growing Season Care

• Regular water + monthly fertilizer until fall.
• Bright indirect light (east/west window, no coverings).

Outdoor summer = easiest, most reliable blooms.
