Don’t Bag It.
Fall Leaves have the same nutrients as the fertilizer you put on the ground this spring. Rake those leaves and compost them or, shred and mulch autumn leaves for some of the best product you can place around your trees and in your gardens.
This is the organic matter we talk about that will make your soil more friable. Use this mulch around your mums after the ground freezes. But first, cut mums to the ground. This will prevent the mums from heaving in the frozen ground. Heaving means the roots are pushed up above ground during freezing weather.
Mums can live for years if trimmed back in the fall.
