Kniphofia triangularis problems — and how to fix them
Kniphofia triangularis (Kniphofia triangularis) 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.
Winter crown rot
Cold, wet soil rots the crown over winter, the commonest cause of loss. Plant in sharp drainage, keep winter-dry, and tie or fold foliage over the crown to shed water.
Few or no flowers
Too much shade, over-feeding or a congested clump reduces blooming. Move to full sun, ease off nitrogen, and divide overcrowded clumps.
Tatty foliage
Old leaves brown and look untidy, especially after winter. Comb out or trim dead foliage in spring rather than cutting the whole clump hard.
Slow recovery after division
Kniphofia resents root disturbance and can sulk after being divided. Divide only in spring, replant promptly, and keep watered while it re-establishes.
