Heath Spotted Orchid problems — and how to fix them
Heath Spotted Orchid (Dactylorhiza maculata) 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.
Loss of colony to vegetation change
Drainage improvements or nutrient runoff from adjacent ground quickly shifts the community toward rank grasses and rushes, eliminating the orchid within a few years — maintain the hydrological and nutritional status quo.
Slug damage to emerging shoots
Spring tuber shoots are vulnerable to slug feeding; iron phosphate-based deterrents are effective and safe for the surrounding acid-heath invertebrate community.
