Common Bird's-foot Trefoil problems — and how to fix them
Common Bird's-foot Trefoil (Lotus corniculatus) 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.
Fusarium wilt
Fusarium oxysporum can colonise roots in wet or poorly drained soil, causing sudden wilting and browning; improve drainage and avoid overwatering.
Aphid infestation
Black bean aphid (Aphis fabae) congregates on new shoots in spring; tolerate light infestations in wildlife gardens or knock off with a jet of water.
