Purple Siberian Melic problems — and how to fix them
Purple Siberian Melic (Melica altissima 'Atropurpurea') 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.
Crown rot from winter waterlogging
The most common cause of plant failure; heavy or poorly draining soils trap winter moisture around the crown, causing rot and dieback. Improve drainage with grit on planting, or raise the planting level.
Self-seeding around the parent plant
Can self-seed quite freely in favourable conditions; deadhead promptly after flowering if unwanted seedlings are a concern, or transplant self-sown seedlings to new positions.
