Cutleaf Toothwort problems — and how to fix them
Cutleaf Toothwort (Cardamine concatenata) 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.
Failure to re-emerge
Rhizomes may rot if soil becomes waterlogged during summer dormancy. Plant in well-drained sites or raise beds slightly to improve drainage.
Slug and snail damage
Emerging spring foliage is attractive to slugs. Apply iron phosphate bait early in the season when shoots first break ground.
Squirrel and rodent disturbance
Rhizomes can be disturbed by burrowing animals. Cover planting sites with a thin layer of wire mesh or plant in areas with established ground cover.
