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.

Of course, free *fresh* seed! Let the lawn miss a cut or two, then
mow high so as not to shock the grass and to help protect the seed
from birds, without catching the clippings of course (a mulching blade
won't harm the seed).
