Late summer is the time to decide what, if any, seeding work your lawn will need this year. Careful advance planning and follow-up can make the difference between seeding success and failure. Below are a few of the conditions that call for seeding work.
Can you see the soil or thatch layer when you look down at the grass? Thinness allows weeds to get started in the lawn and causes the lawn to dry out much faster. A thin lawn should be seeded.
The thatch layer can become so heavy that the primary root system is growing more in the thatch than in the soil below. Shallow thatch-rooted lawns are much more susceptible to drought damage.
Do you want to develop a more disease-insect- or drought-tolerant lawn? There are grass varieties that bugs, diseases and hot weather don't bother as much as others.
