Zinnia 'Profusion' problems — and how to fix them
Zinnia 'Profusion' (Zinnia × hybrida 'Profusion') 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.
Soggy soil / root rot
Though very disease-resistant above ground, it dislikes wet feet. In poorly drained soil or overwatered containers roots rot and plants wilt; ensure drainage and let the surface dry between waterings.
Sparse bloom in shade
Too little sun reduces flowering and loosens the tidy mound. Site in full sun for the dense, flower-covered habit it is known for.
Spider mites in hot, dry spells
Hot, dusty conditions can bring spider mites, seen as fine stippling and webbing on leaves. Rinse foliage occasionally and keep plants from drought-stressing.
Occasional leaf spot late season
Resistance is strong but not absolute; minor leaf spotting can appear in prolonged wet weather. Remove affected leaves and avoid overhead watering to keep it in check.
