Troubleshooting
Cowslip Orchid problems — and how to fix them
Cowslip Orchid (Caladenia flava) 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.
Summer tuber rot
Tubers quickly rot if kept moist during dormancy. Store or maintain in completely dry conditions from late spring through early autumn.
Mycorrhizal failure
Without the correct soil fungi, tubers may persist for a season or two but decline and fail to flower. Native bushland soil inoculant can help but success is unpredictable.
Snail and slug grazing
The single grass-like leaf is a target for slugs. Use protective measures during the autumn emergence period.
Root aphids
These pests can colonise the roots and tuber, especially in container culture. Check the root zone periodically and treat with a soil-drench insecticide approved for containers if detected.
