Well, how did your last renovation work out?

I wouldn't get on it. Not until the first mow. And not with a powerful blower. I also have massive oak trees and I let the leaves drop and hope the new seedlings are ready to reach for the sky. It's an issue we have to endure for a few weeks.

 

The last one turned out good. I was earlier in the season last year though, so I didn't have to start blowing until it was already close to the first mow

 

That looks mild so far. You should be able to wait awhile. I'm dealing with the same issue. We have a huge Big Leaf Maple in the back yard and many other maples around the yard and have had a couple severe wind storms this weekend with more expected littering the yard with leaves and seeds that completely block out the ground in places. Our power was out nearly 24 hours yesterday to today.

I was late seeding due to supplier delays and with the cool weather the coated seeds are just now germinating. I finally used the leaf blower today although I would have preferred to wait. For me I was more worried about a thick covering of maple leaves smothering my germinating grass seed than my footprints. A balance between damage from the leaves vs blowing away grass seed and walking on the lawn. Walking on the seeds was the least of my worries.

 

As long as the leaves dont completely cover the seedlings, I wouldnt be too worried about it. Worst case, maybe once a week blow the leaves off of the grass.
Walking on the grass once a week isnt going to hurt it.

 

I'd wait until 1 week after germination and then gently blow. Seedlings can crawl and try to get light for quite a while before they give up. I saw a photo of a fescue seedling that with moisture it was crawling trying to find light until it was like 5" long. I've seen new seedlings grow and survive under my sprinkler for a week. Right now the leaves trapping the moisture may be a good thing.

But then stay on top of keeping those seedling seeing light after your first blow.

 

Thanks for the tips guys. I think I'll wait a couple more days then lightly blow it off.
