Troubleshooting
Chinese Ground Orchid problems — and how to fix them
Chinese Ground Orchid (Bletilla striata) 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.
Frost damage to new growth
Emerging shoots in early spring are vulnerable to late frosts; protect with fleece or a cloche in exposed UK gardens.
Pseudocorm rot in wet winters
Heavy winter wet kills dormant pseudocorms; improve soil drainage with grit, or lift and store pseudocorms frost-free in a cool, dry place.
Slugs and snails
Young spring shoots are a favourite target; use slug pellets approved for garden use or a physical barrier of grit around the clump.
Failure to flower
Insufficient light or premature transplanting of underdeveloped pseudocorms are the common causes; allow clumps to establish for 2-3 years before dividing.
