Greater Stitchwort problems — and how to fix them
Greater Stitchwort (Stellaria holostea) 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.
Stem brittleness and collapse
Stems snap easily in wind or rain without support from neighbouring vegetation; plant within established hedgerow or meadow communities rather than in isolated positions.
Powdery mildew in late summer
Can develop on foliage after flowering in dry seasons; the plant typically dies back naturally at this point so control is rarely necessary.
