Common Cow-wheat problems — and how to fix them
Common Cow-wheat (Melampyrum pratense) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to establish
The most common issue: seedlings that fail to locate a suitable host root (grasses, heathers, or woody shrubs) in the first weeks die before spring. Sow in autumn in situ next to established host plants.
Slug damage
Young emerging seedlings in spring are vulnerable to slug and snail grazing; use biological controls (nematodes) rather than slug pellets, which can contaminate the low-nutrient soil the plant needs.
