Hi! My name is Pam. I am new here so for give me for posting this twice. I thought it might been seen better here. My husband and I are doing a landscaping job on a property that has some sad looking Pampas. The Blades for the most part are green and healthy although pale, but the stalks and plumes are dead. I have little experience with Pampus ..so I could really use some advise. This is a business ,so the manager would prefer to keep the Pampus .The beds were neglected for quite some time. It is in direct sun in the SE Oklahoma heat, but does have a sprinkler system timed for 4 AM. Please help !!!! Thanks. Pam
