Troubleshooting
Bottle Gentian problems — and how to fix them
Bottle Gentian (Gentiana andrewsii) 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
Overwatering or poor drainage is the primary threat; roots rot rapidly in waterlogged soil. Ensure consistently moist but never saturated conditions and avoid planting in low-lying areas.
Septoria leaf spot
Fungal leaf spot (Septoria spp.) can appear in humid conditions, producing small dark spots on foliage. Improve air circulation and remove affected leaves; avoid overhead watering.
Slug and snail damage
Slugs and snails target young growth and leaves in moist garden settings. Use iron phosphate pellets or place grit barriers around plants at emergence.
