Deschampsia cespitosa 'Pixie Fountain"

Asked August 26, 2016, 1:06 PM EDT

Hi, In May, we had Pixie Fountains planted by a landscaper in the front of the house. They get full sun and are watered by an irrigation system for 30 minutes 3 times a week. They were doing fine, but started to turn brown. The local nursery said they were being over-watered, so we cut back. They continued to turn brown. The landscape/fertilizer person said they were not getting enough water, so we put them back to 3 times a week for 30 minutes. They are still brown. As we are first time gardeners, your advice would be greatly appreciated. Thank you.

I don't have a definitive answer. You could take a soil test and see if the pH is very low or very high. If they wee overwatered they would have turned brown because the roots died due to being waterlogged and not having enough oxygen. At that point, there is nothing you can do, reducing the watering wouldn't bring the roots back to life.
