Autumn Gentian problems — and how to fix them
Autumn Gentian (Gentianella amarella) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to establish from seed
Seedlings are tiny and easily smothered by coarse grasses or moss; rake or scarify the soil surface before sowing and maintain short turf through the growing season.
Root rot / damping off
The basal rosette collapses in waterlogged or compacted soils; grow only in freely draining positions and avoid overhead watering of pot-grown seedlings.
