Troubleshooting
Pelargonium gibbosum problems — and how to fix them
Pelargonium gibbosum (Pelargonium gibbosum) 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.
Stem and root rot
The swollen nodes rot fast if watered during summer dormancy or grown in heavy soil. Keep it nearly dry when resting and use a gritty, fast-draining mix.
Etiolation
Thin, stretched, weak stems mean too little light. Move it to the brightest window or full sun to keep the jointed habit compact.
Summer leaf drop
Dropping its leaves in summer is normal dormancy, not death. Reduce water and wait for autumn regrowth rather than overwatering to revive it.
No flowers
Failure to bloom usually traces to insufficient light or overly rich feeding. Give full sun and a high-potassium feed during active growth.
