Troubleshooting
Oxalis tetraphylla problems — and how to fix them
Oxalis tetraphylla (Oxalis tetraphylla) 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.
Sudden die-back / dormancy
Not death but normal dormancy after flowering or in heat. Cut back, keep bulbs cool and nearly dry, and growth resumes next season.
Rust fungus
Orange pustules on leaves in damp, crowded conditions. Improve airflow, remove affected foliage, and avoid overhead watering.
Leggy, pale leaves
Insufficient light. Move to a brighter spot to firm up growth and restore the dark cross markings.
Bulb rot
Overwatering, especially during dormancy. Use gritty mix and keep dormant bulbs almost dry.
