Cuphea hyssopifolia problems — and how to fix them
Cuphea hyssopifolia (Cuphea hyssopifolia) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frost damage
Tender to cold; foliage browns and dies back below freezing. Mulch roots and overwinter in containers indoors in zones colder than 9.
Leaf drop in dry soil
Lets foliage thin and flowering slow if it dries out repeatedly. Keep soil evenly moist, especially in heat and containers.
Sparse flowering in shade
Too little sun produces lush leaves but few blooms. Move to a sunnier position for continuous flowering.
Spider mites and aphids
Occasional sap-sucking pests, more common indoors or in dry, dusty conditions. Rinse foliage and treat with insecticidal soap if infestations build.
