Soft Draba problems — and how to fix them
Soft Draba (Draba mollissima) 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.
Crown rot from winter wet
The principal challenge in cultivation; even brief exposure to standing moisture on the cushion in cool conditions causes irreversible rot — winter glass or cloche cover over an outdoor trough is strongly recommended.
Failure to flower
Plants in insufficient sun or overly rich soil grow vegetatively but refuse to bloom; ensure maximum light and lean soil, and avoid any nitrogen-heavy fertiliser.
