Tufted Vetch problems — and how to fix them
Tufted Vetch (Vicia cracca) 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.
Aphids (blackfly and vetch aphid)
Dense colonies of black bean aphid and vetch aphid commonly colonise shoot tips and flower buds from late spring; encourage natural predators or knock back with a jet of water.
Powdery mildew in late season
White powdery fungal coating appears on older leaves during hot, dry spells in late summer; this is usually cosmetic and does not threaten plant survival; good airflow reduces severity.
