Glandular Heron's Bill problems — and how to fix them
Glandular Heron's Bill (Erodium glandulosum) 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
The most common killer; caused by waterlogged soil or poor air circulation in winter wet. Prevent by planting in raised beds or adding a collar of grit around the crown.
Vine weevil larvae
Grubs feed on roots, causing sudden wilt; inspect roots when repotting and treat with nematodes (Steinernema kraussei) in early autumn.
