Troubleshooting
Candy Cane Sorrel problems — and how to fix them
Candy Cane Sorrel (Oxalis versicolor) 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.
Bulb rot
The primary problem; caused by waterlogged compost. Ensure excellent drainage and water only when partly dry.
Flowers fail to open
Normal response to low light or overcast weather — this species is photonastic (opens with sun). Move to a brighter position if flowers remain closed even on sunny days.
Dormancy confusion
The plant goes fully dormant in summer; the pot may look dead. Mark and withhold water until autumn regrowth.
Overcrowding of bulbs
After 2-3 years, flowering declines as bulbs overcrowd. Lift, divide, and replant at correct spacing in autumn.
Vine weevil
Larvae damage small bulbs in containers. Use biological control (Steinernema kraussei) in autumn.
