Troubleshooting
Good Luck Plant problems — and how to fix them
Good Luck Plant (Oxalis deppei) 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.
Overwatering in dormancy
After leaves die back in autumn the bulbs must rest dry. Continuing to water causes bulb rot. Stop watering when leaves yellow.
Leggy growth
Caused by insufficient light. Move to a brighter spot; the distinctive iron cross pattern is also best visible in good light.
Spider mites
A common problem on indoor plants in dry conditions. Increase humidity and treat with insecticidal soap if webbing appears.
Bulb overcrowding
Flowering diminishes when bulbs are crowded. Lift and divide every 2-3 years, replanting healthy bulbs at 3-4 cm depth.
Leaf fold in afternoon heat
Nyctinastic leaflet folding in strong sun or at night is normal; not a sign of stress.
