Troubleshooting
Ruby Ribbons Switch Grass problems — and how to fix them
Ruby Ribbons Switch Grass (Panicum virgatum 'Ruby Ribbons') 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.
Loss of compactness
Rich soil or shade makes this normally tidy cultivar splay. Keep it in full sun on lean soil for the tight upright form.
Weak red tones
Too little sun or over-feeding suppresses the burgundy. Increase light and stop fertilising to bring back the colour.
Rust and leaf spot
Fungal spotting in humid, crowded sites. Improve air circulation and avoid overhead watering.
Hollow, dying centre
Older clumps thin out in the middle. Divide in spring every few years to renew vigour.
