A second problem is that my purple fountain grasses are not looking their best. They were planted last summer and did well. I pruned them to 8 inches at the beginning of spring. They grew nicely. But sometime in July the seed heads turned completely white. And then a few weeks later, half of them lost their seed heads and all of them lost their purple color and are now completely green. So now I have these 4 foot clumps of green grass. Help! I have no idea what has happened. What can I do to get their purple color back, and why did half of them lose their seed heads?
