To kill the crabgrass or not to kill?
I have a lot of crabgrass mixed into my bermuda lawn. I would say 75% bermuda and 25% crabgrass. I fertilize with soybean meal every month and give my lawn 1 inch of water every week. Also I mow at 1 inch every 3-4 days. I can deal with the crabgrass knowing it will die at the first frost but was wondering if it would be best to kill it now or just let it go? I guess I have several thoughts on this starting with keeping my lawn mowed every 3-4 days to prevent seed heads. Would mowing this often keep the seed heads from coming up and producing more crabgrass next year? I will be using CGM for a pre-emergent this fall and spring with hopes of some help. I have some crabgrass killer from garden weasel which contains cinnamon but not sure if I want to go that route. I was hoping the bermuda would choke out the crabgrass but not sure if that will ever happen. Okay so what should I do? I'm open to suggestions and ideas. Thanks guys!!!
