Troubleshooting
Scarlet Passion Flower problems — and how to fix them
Scarlet Passion Flower (Passiflora miniata) 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.
Spider mites
Thrive in hot, dry conditions; mist regularly and treat with neem oil or insecticidal soap at the first sign.
Aphids
Cluster on new growth tips; knock off with a sharp stream of water or apply a dilute soap spray.
Root rot
Results from waterlogged soil; ensure excellent drainage and reduce watering frequency in cooler months.
Failure to flower
Usually caused by insufficient light or excessive nitrogen; move to a sunnier position and switch to a high-potassium feed.
Powdery mildew
White dusty patches on leaves in humid, still air; improve air circulation and treat with a dilute bicarbonate-of-soda spray.
