Pignut problems — and how to fix them
Pignut (Conopodium majus) 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.
Transplant failure
The slender stem connecting the tuber to the shoot snaps easily during lifting; always transplant as a dormant tuber in late summer and handle with extreme care.
Competition from coarse grasses
Vigorous grasses smother the delicate pignut foliage; plant in fine-leaved grassland or keep the immediate area lightly weeded to give seedlings space to establish.
