|If we plant new St. Augustine grass, which is supposed to be resistant to the decline, and leave the old grass which has St Augustine decline, will the new grass be affected?|
I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
You can plant a new resistant variety of St. Augustine grass into the decline infected turf and the new grass will not be affected.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
