Troubleshooting
Spiny Ruschia problems — and how to fix them
Spiny Ruschia (Ruschia pungens) 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 rot from overwatering
The principal threat. Ensure fast-draining soil and full soil drying between waterings, especially in winter.
Mealybugs in spiny growth
The dense, spiny habit provides good cover for mealybugs. Inspect regularly with a magnifying glass; treat with alcohol-dipped swabs or systemic insecticide.
Spine-tip injury handling
Use thick gloves when repotting; the rigid, sharp leaf tips can cause skin punctures. Not a plant problem per se, but a handling precaution.
Loss of compact habit
Inadequate light causes lax, open growth. Ensure maximum direct sunlight at all times.
Failure to flower
Cool, dry winter dormancy is often needed to stimulate spring flowering. Keep dry and cool (but frost-free) from autumn to late winter.
