Crocosmia × crocosmiiflora 'Jackanapes' problems — and how to fix them
Crocosmia × crocosmiiflora 'Jackanapes' (Crocosmia × crocosmiiflora 'Jackanapes') 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.
Vigorous spreading
Corm chains multiply and can outgrow their space. Lift and divide every few years and remove stray corms to keep clumps in bounds.
Poor flowering
Caused by congestion, deep shade, or overcrowded corms. Divide tight clumps, move into more sun, and feed with potash before bloom.
Spider mites in hot, dry spells
Fine mottling and webbing on stressed foliage. Keep plants watered, raise humidity around the leaves, and rinse off mites.
Winter corm rot in cold, wet soil
Corms can rot in waterlogged ground over winter. Improve drainage or, in the coldest gardens, mulch deeply or lift and store corms.
