purple fountain grasses

Question

We live in Southport, NC. Planted about 12 – each in their own large pot. Used Miracle Grow soil. I one month they are four feet tall and almost fully tasseling in mid June.

Are they going to mature too quickly? If I cut off their tassels, would the energy go into preserving the foliage and not the tassels/seeds? Would this help the plant to have a longer life?

Answer 1

Cutting the plums now would likely cause the plant to go into dormancy. Your plant should grow and look nice well into late summer and early Autumn and actually look great as a winter accent.
