Default Solution to st augustine invading zoysia

If, you use a lawn service sooner or later you will find St Augustine invading. The problem is they pick it up from other lawns. The St Augustine will grow from small pieces.
In fact that is how the sod farms plant it.

To win this war you need to understand the enemy. St Augustine spreads by surface runners. So long strings of it are connected together.

If you take a convex rake, we used to call it a push pull rake, and drag it through the St Augustine, it will pull out the ends but not the tap root. You coat the now raised ends with one of the kills all type products. You want to READ the label to be sure it is NOT one of the long lasting ones. You coat each plant with a rag or small paint brush dipped in the mixed weed killer. In about a week it will kill the St Augustine AND ANY OTHER PLANTS THAT YOU HAVE PUT THE WEED KILLER ON.

After you or your gardener mows on a hot day, you spray that area with one of the 2-4d weed killers. Weed-b-gone is one of the brand names. Buy the liquid mix it at double the recommendation. I used a Windex type bottle, It is 28 oz and I mixed in 1 tps of the weed killer. IT WILL KILL ANY REMAINING ST AUGUSTINE-takes about 2 weeks. It will damage the zoysia but it will recover. St Augustine will not take as much 24D as the zoysia can.
