Phalaenopsis Death Spiral: Night Watering, Crown Rot, and the Bottom-Watering Solution

Pattern of Loss: Water on Leaves Overnight

Three Phalaenopsis declining rapidly with black centers and leaf drop. The common factor: water on leaves overnight. Evening watering creates cool, wet conditions where fungus explodes overnight.

Morning-Only Watering Rule

Water early so leaves dry by nightfall. Add gentle air movement. Fungicide helps but requires constant application—prevention beats treatment.

Bottom-Watering Technique

Place pot in deep bowl. Add lukewarm water to just below mix surface. Soak 30 minutes. Remove, drain thoroughly, return to growing area. Zero water on leaves.

Early Fungus Removal

Black sooty spots at leaf bases = active fungus. Alcohol-dipped Q-tip within 24 hours of appearance can stop spread.
