Common Issues in St. Augustine Grassthatch layer buildup st augustin grass

Thatch

Over-fertilization and soil pH are two of the biggest culprits in thatch build up. A core soil test will tell you what your soil’s pH is. If you are interested in a core soil testing Superior Spray would be happy to perform one for you. You can schedule a test by calling 863-682-0700.  Another reason for thatch development is excessive watering. Watering your grass, whether it needs it or not, can result thatch buildup. If the thatch dries out, it can crust over and become “hydrophobic”. Meaning water can not penetrate it, but instead, will puddle on the surface. Tests have shown that  nearly 100% of fertilizers, pesticides, and herbicides can not penetrate a heavy thatch and will become trapped on top of it. Core aeration can be a solution to breaking up thatch allowing water, air, fertilizers and insecticides to reach the root system. After an aeration, leave the soil cores on the grass. They will break down naturally and feed the soil’s micro-organisms.

Insects

The major pest of St. Augustine grass in Florida is the chinch bug. This tiny insect has needle like piercers that suck out the grass’s juices. Their saliva is also toxic to St. Augustine grass and compounds the damage.
