Troubleshooting
Kohleria 'Hannah Roberts' problems — and how to fix them
Kohleria 'Hannah Roberts' (Kohleria 'Hannah Roberts') 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.
Leaf spotting
Droplets resting on the fuzzy leaves leave marks and invite fungus. Water at the base or from below and avoid misting the foliage.
Sparse blooms
Most often too little light. Provide brighter indirect light or a grow light and feed with a high-phosphorus fertiliser to push flowers.
Sudden collapse to rhizomes
Usually a natural winter semi-dormancy, not loss of the plant. Keep the rhizomes barely moist and warm and growth restarts in spring.
Rhizome rot
Caused by soggy, compacted soil. Use an airy mix, water moderately, ensure good drainage, and cut watering right back over winter.
