Huron Sunrise Miscanthus problems — and how to fix them
Huron Sunrise Miscanthus (Miscanthus sinensis 'Huron Sunrise') 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.
Sparse or late plumes
Often a sign of too little sun or a cool, short season; site in the hottest, brightest spot available.
Miscanthus rust
Rusty pustules in humid, crowded plantings. Space clumps, avoid wetting foliage, and remove infected leaves.
Hollow, dying centre
Mature clumps thin out in the middle. Divide every three to four years in spring to restore vigour.
Winter collapse
Snow load and wind can flatten the standing clump; this is cosmetic, and stems are simply cut down in late winter.
