Wild pansy problems — and how to fix them
Wild pansy (Viola tricolor) 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.
Powdery mildew
White powdery coating on leaves in warm, humid or dry conditions. Improve air circulation by thinning plants and avoid overhead watering. Remove affected growth and treat with a diluted neem oil spray if severe.
Aphids
Dense colonies on new growth cause distortion and stunting. Knock off with a strong jet of water or apply insecticidal soap. Encourage natural predators (ladybirds, lacewings) by avoiding broad-spectrum insecticides.
Pansy leaf spot (Ramularia agrestis)
Tan to brown circular spots with purple margins on leaves. Remove and destroy affected foliage. Improve air circulation and avoid wetting leaves when watering. Most plants recover fully once conditions dry out.
