Troubleshooting
Standish's Golden Yew problems — and how to fix them
Standish's Golden Yew (Taxus baccata 'Standishii') 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.
Phytophthora root and collar rot
Waterlogged conditions allow Phytophthora cinnamomi to attack the root collar, causing rapid browning from the base up and resinous cankers at the soil line. Improve drainage immediately; no chemical cure is reliable once symptoms are advanced.
Vine weevil (Otiorhynchus sulcatus)
C-shaped white grubs feed on roots through autumn and winter, causing sudden wilting and death in container-grown or young specimens. Apply Steinernema kraussei nematodes (biological control) to moist soil in September, or use imidacloprid as a soil drench.
