Trailing Lantana problems — and how to fix them
Trailing Lantana (Lantana montevidensis) 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.
Whitefly and sooty mould
Clouds of whitefly on the undersides of leaves cause yellow stippling; their honeydew deposits lead to black sooty mould. Treat with insecticidal soap or neem oil and improve air circulation.
Root rot from overwatering
Sitting in wet soil causes rapid root rot, leading to yellowing foliage and stem collapse. Ensure excellent drainage and reduce watering frequency, especially in cooler weather.
