Troubleshooting
Creeping Willow problems — and how to fix them
Creeping Willow (Salix repens) 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.
Willow aphid (Pterocomma species)
Dense colonies of dark aphids can coat young shoots in summer, causing distorted growth and sticky honeydew; treat with insecticidal soap or encourage natural predators such as ladybirds.
Honey fungus (Armillaria spp.)
Willows are notably susceptible to honey fungus, which causes sudden wilting and death of shoots; look for white mycelial fans under bark at the base. There is no chemical control — remove and destroy affected root material.
