Answer: Well, you are right, it's a good idea to avoid raking if possible, to avoid disturbing the seedlings. If you have just a few leaves scattered about, I would leave them in place. However, if you have a thick layer of leaves, you will need to remove them because a heavy blanket of fallen leaves can suffocate the seedlings. Rake them up as gently as possible to avoid damaging the seedlings. If the new grass is 3-4" high, it is time to mow it, so if you have a mulching mower, that would be an option for dealing with the leaves.
