I have an area where I have a large crabgrass problem that I want to overseed. I wanted to get the seedng done last fall but circumstances prevented it. Now I'm considering using a product with Tupersan to control the crabgrass and allow me to seed. I plan to put down the tupersan, and then the seed and a starter fertilizer. I understand that the Tupersan products only last about 30 days which, hopefully will be long enough to allow the seed to germinate. Then I'll put down a standard crabgrass preventer. Does this sound like a good plan? The area I want to use the Tupersan on will have a pretty heavy crabgrass growth if I don't do anything. Does Tupersan really work on an area that has a lot of crabgrass? I don't mind spending the money to put it down but I don't want to waste it if I'm not going to get the results I want.
