Geisha Girl flowering quince problems — and how to fix them
Geisha Girl flowering quince (Chaenomeles speciosa 'Geisha Girl') 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.
Aphids on new growth
Dense colonies of greenfly in spring on tender shoot tips, causing leaf curl. Remove by hand or strong water spray; insecticidal soap is effective and low-impact on beneficials. Encourage predatory insects.
Leaf spot (Fabraea maculata)
Brown or purple leaf spots with yellow halos in wet summers; premature leaf drop. Remove fallen leaves promptly; improve air circulation by light summer pruning; copper-based fungicide applied preventively in spring helps.
Failure to flower after hard pruning
Flowers form on second- and third-year spurs on older wood. Prune only immediately after flowering ends; cutting in autumn or winter removes the following season's flower buds. Remove only the oldest, most congested stems annually.
