Yellow Germander problems — and how to fix them
Yellow Germander (Teucrium flavum) 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.
Winter dieback on wet, heavy soils
Established plants usually reshoot from the base after cold winters, but persistent waterlogging in winter is fatal; improve drainage before planting rather than hoping for recovery.
Flea beetle damage
Small holes in the leaves during late spring and summer are typically caused by flea beetles feeding on the aromatic foliage; light infestations are cosmetic only but heavy attacks can weaken plants — insect-mesh or a pyrethrum-based spray controls them.
