Hameln Dwarf Fountain Grass problems — and how to fix them
Hameln Dwarf Fountain Grass (Pennisetum alopecuroides 'Hameln') 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.
Late or sparse plumes
Needs a warm, sunny site and a long enough season to flower well; in cold, shady spots it may flower little or not at all.
Floppy clump
Shade or over-rich, over-watered soil loosens the tidy mound; full sun and lean soil keep it compact.
Self-seeding
Unlike the sterile purple types, this species can set viable seed; deadhead the plumes if unwanted seedlings are a concern.
Winter crown rot
Cold, waterlogged soil rots the crown over winter; ensure sharp drainage, particularly in heavy ground.
