Troubleshooting
Gryphon Begonia problems — and how to fix them
Gryphon Begonia (Begonia 'Gryphon' (Begonia x hybrida)) 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.
Root and stem rot
Caused by overwatering or poorly draining soil. Let the top inch dry between waterings and use a gritty, well-draining mix in a pot with drainage holes.
Powdery mildew and botrytis
White powdery patches or gray mold appear in humid, stagnant air. Improve airflow, avoid wetting the leaves, and space plants so foliage can dry.
Leaf scorch
Bleached or crispy brown patches from too much direct sun. Move to bright indirect light behind a sheer curtain.
Mealybugs and spider mites
Look for white cottony tufts or fine webbing and stippled leaves. Wipe off with diluted isopropyl alcohol or treat with insecticidal soap.
Whitefly and thrips
Common begonia pests, especially on plants moved outdoors. Inspect leaf undersides and treat with insecticidal soap or sticky traps.
Leggy, faded growth
Stretching stems and weak silver coloring signal too little light. Move to a brighter (still indirect) spot to restore compact, vivid foliage.
