Aunt Eliza Montbretia problems — and how to fix them
Aunt Eliza Montbretia (Crocosmia paniculata) 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.
Stem flopping
Tall stems may need staking in exposed gardens; plant in a sheltered spot or use grow-through supports.
Corm rot
Wet winter soils are the primary cause; improve drainage before planting.
Clump congestion
Productivity declines after 3-4 years; lift and divide corms in spring to rejuvenate.
Rust (Puccinia crocosmiae)
Orange pustules on leaves; remove affected foliage and improve air circulation.
Vine weevil
Larvae may feed on corms; apply beneficial nematodes in late summer as a biological control.
