Troubleshooting
Sky Rocket Feather Top problems — and how to fix them
Sky Rocket Feather Top (Pennisetum alopecuroides 'Sky Rocket') 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.
Fading variegation
Too little sun causes the white striping to wash out toward plain green. Site in full sun to keep the contrast bright.
Borderline winter hardiness
Variegated forms are slightly less hardy than the green species. In colder zones mulch the crown or overwinter container plants in a sheltered spot.
Crown rot in wet soil
Waterlogged ground over winter rots the crown. Ensure sharp drainage and keep mulch off the base.
Reversion to green
Occasional all-green shoots can appear and outcompete variegated growth; remove plain-green stems at the base as they emerge.
