Hibiscus syriacus 'Minerva' problems — and how to fix them
Hibiscus syriacus 'Minerva' (Hibiscus syriacus 'Minerva') 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.
Bud drop
Unopened buds fall, usually due to drought stress or inconsistent watering. Keep the soil evenly moist throughout the flowering period.
Aphids on tender growth
New shoots and buds attract aphids, producing sticky honeydew and sooty mould. Rinse off or apply insecticidal soap; natural predators help.
Late dormancy break
Rose of Sharon leafs out very late in spring and can appear dead. Confirm green tissue beneath the bark before assuming winter loss.
Chlorosis in poorly drained soil
Yellowing leaves and dieback can follow waterlogging. Improve drainage, ease off watering, and mulch to stabilise soil moisture.
