Mutton Bird Sedge problems — and how to fix them
Mutton Bird Sedge (Carex trifida) 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.
Poor performance in hot, dry summers
Unlike many drought-tolerant ornamental grasses, this sub-Antarctic species dislikes heat and dry conditions; foliage browns and growth stalls in prolonged summer drought. Water regularly and apply a deep organic mulch.
Slug damage on new leaf shoots
Emerging leaf rolls are susceptible to slug and snail grazing in spring, which leaves longitudinal holes and scarring. Apply iron-phosphate pellets around the crown in early spring before growth emerges.
