My bluegrass lawn here in the DC area sprouts seeds at the tips every year
about this time. Is there a way to take advantage of these free seeds by
letting the grass get a little higher between cuts, not mulching etc? It
would be nice to return those seeds to the soil to thicken up the lawn.

We do that on our pasture grasses all the time here on the farm so if you
want to do it on a lawn the same principles would apply. Don't graze (in
your case, mow) until the seed heads are mature and the seed drops back onto
the ground.
