Fertilizing for Bud Formation
Nutrition plays a critical role in preparing your Christmas cactus for blooming. September is when you shift from growth fertilizer to bloom booster.
Fertilizer Schedule in September
Stop high-nitrogen feeding: Fertilizers rich in nitrogen encourage leaf and stem growth, which you don’t want now.
Switch to phosphorus and potassium: Use a fertilizer with a ratio like 5-10-10 or 2-7-7, which promotes strong flower bud development.
Frequency: Feed every 2–4 weeks until late October, then stop until after blooming.
