|I planted Cyperus Papyrus in my yard and it is truly fulfilling the purpose that I had hoped for, privacy, beauty, ease of maintenance etc. The problem is that my Cyperus Papyrus is an overchiever. So much so that it is over 8 feet high and has become as invasive as any plant could get. It grows like weeds!
I cut it back just above the base of the stalk but it doesn't seem to stop it. What is the best way to keep it at bay and confined?
|Cyperus Papyrus is indeed a vigorous plant. Yours sounds too happy! The best way to control the growth is to confine the root system. Dig it up while you still can, divide it, and plant it in a large container. You can bury the container in the ground if you wish. Keeping the roots confined will keep the top smaller. You'll still have an attractive plant, but it will be much smaller and easier to take care of.
Best wishes with your landscape!
