Why Christmas Cactus Struggles to Bloom Indoors
Unlike desert cacti, Christmas cactus prefers slightly acidic soil. Over time, tap water and standard fertilizers slowly raise soil alkalinity, blocking nutrient uptake.
When this happens, the plant:
- Produces fewer buds
- Drops flowers early
- Shows dull leaf color
Interior plant specialists focus on micro-adjustments, not heavy feeding. That’s where baking soda—used correctly—makes a difference.
