This year the leaves from our big maple tree have come down nice and slowly. There hasn't been a lot of wind to blow them all into the marsh behind the tree. So it seemed like a good idea to get them raked up before the wind start to blow (and it is blowing out there right now) and get the dahlias mulched for the winter.
I don't dig my dahlias because I don't have a really reliable place to store them without having the tubers freeze. Covering them with a heavy mulch has worked just fine for years. And it was fun to rake up all the leaves and then dump them on the dahlias.
