Hot weather grasses (like Bermuda and St. Augustine) are drought tolerant and have the benefit of crowding out weeds. The clay content of Texas soil has the added benefit of preventing much root growth, so stubborn weeds that flourish up north are benign down here.

Mowing short in this heat is a death sentence to grasses that aren't drought tolerant, and can introduce disease with the short blade and exposed root system. I am assuming that the only grasses that can grow in CT are Kentucky Blue or Zoysia, and perhaps Fescue.

This is about the time of the month to see secondary weed growth that seemed to have been handled during the spring pre-emergence applications. All you can really do is more chemical application to prevent further spread. But if your neighbor has a bumper crop of crabgrass, you will have a tough time keeping yours in check...
