Red Sheep Laurel problems — and how to fix them
Red Sheep Laurel (Kalmia angustifolia f. rubra) 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.
Unwanted rhizome spread
Forms dense thickets via spreading underground rhizomes that can crowd out neighbouring plants; install a root barrier at planting or remove suckers regularly at the soil surface.
Lace bugs (Corythucha species)
Cause stippled, silvery discolouration of leaves with dark spots of excrement on the undersides; plants in full sun are most susceptible. Treat with insecticidal soap or neem oil and improve soil moisture to reduce plant stress.
