Forrest's Ginger Lily problems — and how to fix them
Forrest's Ginger Lily (Hedychium forrestii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slug and snail damage
Young emerging shoots in spring are highly attractive to slugs and snails; use biological controls (Phasmarhabditis hermaphrodita nematodes) or copper barrier tape around container rims, especially in wet UK springs.
Stem die-back before flowering
If the growing season is too short or cool, pseudostems may not mature in time to flower; grow against a warm wall or in a large container that can be moved under glass from late summer.
