How long should i wait til after i roundup to aerate and overseed or to till and overseed? Waiting til its dead on the surface would be the bast case but, after it has been taken in by the plant would it matter if it was tilled in the next day?
read the label on Roundup. it will probably say 14-21 days. remember roundup translocates thru the plant. if you go in next day, you may be chopping up the pathway, and while it may kill the top of the plant, it may not have time to get to all the roots.
Also, if you go in and till, there is great potential that you will stir up more weed seed that has been sitting below a depth where it could germinate.
Aerate and if your area is very patchy or thin use a slice seeder to get the best germination possible.

10-13 days and you are good to seed. On Bermuda it takes 2 apps 2 weeks apart then seed two weeks after.
