Troubleshooting
Broomsedge Bluestem problems — and how to fix them
Broomsedge Bluestem (Andropogon virginicus) 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.
Aggressive self-seeding on disturbed ground
Broomsedge can self-seed prolifically in open, disturbed, or low-fertility areas, spreading well beyond its intended position. Deadhead seed heads in autumn if spread must be controlled. In native restoration plantings, self-seeding is generally desirable.
Fire risk in dry conditions
The persistent dry straw-like foliage is highly combustible in winter and early spring. Do not plant immediately adjacent to structures or wood fencing in dry climates. In regions that practice prescribed burning, it is a keystone fire-adapted species.
Mistaken for a dead plant in winter
The vivid orange-copper winter colouration is an ornamental feature, but new gardeners may mistake the dormant clumps for dead material and remove them. Leave clumps standing through winter; cut to the ground in late winter before new growth begins.
