Round-leaved Sage problems — and how to fix them
Round-leaved Sage (Salvia subrotunda) 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.
Leaf scorch
Large leaves are prone to scorching when exposed to harsh afternoon sun in summer; reposition to a site with afternoon shade or install shade cloth during the hottest weeks.
Aphid infestation
Soft new growth on vigorous stems attracts aphid colonies; dislodge with a strong jet of water or treat with insecticidal soap — avoid systemic insecticides during the long pollinator-attracting flowering season.
