Pampas Grass

Question

We live in Michigan and we have pampas grass. We cut the plant down in the early spring, but leaving about 5 inches above the ground of the dried canes. Our grass grows only on the outside of the clump. Are we doing something wrong, or is this the natural habit.

Answer 1

The inner core dies out. You will need to dig it up and divide the plant next spring. It is a whale of a task, in my experience. Once it is out of the ground, pitch the dead core and select outer sections to replant. If you do this every 3 years, it isn't that bad a task but if the grass is, say, 10 years without dividing, you are in for some work!
