Troubleshooting
Evergold Japanese Sedge problems — and how to fix them
Evergold Japanese Sedge (Carex oshimensis 'Evergold') 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.
Leaf tip browning
The most common problem — triggered by drought, over-dry air in heated rooms, or root congestion in pots; water more regularly and repot into fresh compost if the plant has become severely pot-bound.
Green reversion
Plain green shoots occasionally appear in the variegated clump; remove these promptly by cutting them out at the base, as the more vigorous green growth will dominate the golden form if left unchecked.
Vine weevil (Otiorhynchus sulcatus)
White grubs feed on the roots of container-grown plants, causing sudden collapse; treat with nematode solution (Steinernema kraussei) in late summer or early autumn when soil is warm.
