Overseeding

[BLC1]

If I overseed a lawn, how long should I wait to mow it?

Wait long enough until you can't stand it anymore. We were taught that you shouldn't let it get too tall before you mow it. As soon as you mow it it starts spreading better and root growth gets stronger.

On bare spots, I usually say 1.5- 2 weeks after germination. Even on the first mow though, I like to throttle down my mower so I don't get too much lift if there is shallow root growth.

If it is a whole yard, I wouldn't worry about it, just mow. If anything has taken hold it will stay there.
