Queeny Lime Orange zinnia problems — and how to fix them
Queeny Lime Orange zinnia (Zinnia elegans 'Queeny Lime Orange') 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 fungal coating on older leaves in humid or crowded conditions. Improve spacing, water at the base, and apply a sulfur-based or neem-oil spray at first sign. Remove heavily infected foliage.
Alternaria leaf spot
Small brown spots with purple halos appear on foliage, especially in wet conditions. Remove affected leaves, avoid overhead irrigation, and apply copper-based fungicide preventively in damp weather.
Spider mites
Fine stippling and webbing on leaves during hot, dry spells. Blast foliage with water, increase humidity around plants, and apply insecticidal soap or neem oil. Avoid broad-spectrum insecticides that kill predators.
