Perennial fountain grass
We have white patches in our grass which our landscaper said came from the fountain grass throwing seed. The lawn mover just shredded it at the top leaving the white patches/spots. The grass below the shredded tops is fine. We like the fountain grass and don't want to dig it up. If we cut off the tip(which I am guessing is where the seeds come from)will that solve the problem? We started off with one white patch and now we have about 10 going in a row up one side of our driveway. I am a novice at this so any advice you have would be good. The landscaper could not give me a firm answer. We have not noticed this problem in anyone else's yard. The plants are about 4 years old now and healthy looking.
