Mexican Orange Sage problems — and how to fix them
Mexican Orange Sage (Salvia fallax) 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.
Frost kill
Frost above -1°C will damage foliage and a hard freeze will kill the plant outright. Move containers under cover before autumn frosts or take cuttings in late summer to ensure stock for the following year.
