Troubleshooting
Silverbush problems — and how to fix them
Silverbush (Convolvulus cneorum) 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.
Root rot / winter wet
The leading cause of plant loss; ensure beds drain freely and consider raising plants on mounds or in containers in high-rainfall gardens.
Honey fungus (Armillaria)
Occasionally susceptible; the RHS lists honey fungus as a rare but serious issue — remove and destroy infected plants and roots, and do not replant with susceptible species in the same spot.
