Troubleshooting
Begonia 'Zip' problems — and how to fix them
Begonia 'Zip' (Begonia 'Zip') 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.
Powdery mildew
White powdery patches on leaves from stagnant air and overhead wetting. Improve airflow, avoid wetting foliage, and remove affected leaves.
Rhizome and crown rot
Mushy, blackening rhizome from overwatering or a too-deep pot. Use a gritty, free-draining mix and let the surface dry between waterings.
Crispy leaf edges
Browning margins signal low humidity or dry air near heaters. Raise humidity with a pebble tray and move away from radiators and vents.
Leggy, faded growth
Stretching stems and washed-out markings indicate too little light. Move to a brighter spot with strong indirect light to restore compact, patterned foliage.
