Thatch is a problem when you start seeing problems in your turf. If thatch gets too bad, your renovation of thatch will give you numerous problems and take out big chunks of turf in the process. I ve got a lot of weeds in my lawn but prefer not to use chemicals. The first things we try to teach our students are ways to remove weeds without the use of chemicals. The best weed control is a healthy turf.
Some weeds are very easy to remove with a knife or tool made especially for that.
My lawn is roaring with dandelions. Dandelions can be removed by hand or chemically with herbicide. I m building a new home, and the contractor has asked me to specify what type of sod I want to use. I saw a bumper sticker recently that said Life is Short, Sod It . Sod has become a preference for many homeowners.
