Common Wormwood problems — and how to fix them
Common Wormwood (Artemisia absinthium) 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.
Aphids and gall midges
The RHS notes aphids and gall midges as the main pest issues; these are usually manageable with a strong water jet or insecticidal soap; avoid broad-spectrum insecticides on a herb.
Honey fungus
Occasionally susceptible to Armillaria root rot, especially in poorly drained soils; there is no cure once established — remove affected plants and improve drainage before replanting.
