Catching some spring fall

In my backyard I’ve been experiencing at times a blizzard of ‘things’ (no leaves, autumn is for that) falling from the trees – old flowers, stems, bud coverings, I’m not sure what else. Why not get a sheet, tarp, baskets, bowls, upside down opened umbrellas, and place on the ground under a bunch of trees and see what you ‘catch’. You may get some surprises.
