Fall Leaf Management
By John Fulton

[October 22, 2016]  Mid-October, and a bit of wind, leads to falling leaves in increasing numbers. This brings up one of those age old questions “What do I do with all those leaves?” This brings about one of the “dust it off and re-use” columns. The simple answer is to give you three options: leave them (no pun intended), remove them, or chop them up.

If you decide to let nature take its course, letting leaves lie brings benefits and some problems. Many of the benefits are associated with your labor, or lack of it. The major non-labor benefit is when leaves collect in flower beds and around shrubs to provide a mulch for those plants. Problems generally develop where deep piles of leaves may smother grass or harbor diseases, causing large dead areas to deal with next spring. Of course if you are the only resident in a neighborhood who doesn’t rake leaves, you may be talked about at many social functions this fall.

Removing leaves is generally done by raking or bagging with a mower attachment. This makes your lawn look neat, prevents problems for lawns, and gives you a workout if you are manually raking. The main problems are the time, labor, and disposal of the leaves when they are piled.

Chopping leaves means reducing the size. Benefits include less smothering, quicker breakdown, and less labor. The main drawback comes with deep piles that still should be removed because of trouble in shredding and smothering. Early in the season, simply mowing leaves provides a good option.

One thing to consider is the type of leaves. There is a huge difference in oak leaves and silver maple leaves. It’s difficult to have smothering problems with oak leaves, while silver maple leaves may smother with a very thin layer. Many green leaves were blown down Sunday with the high winds. These green leaves will tend to smother more than the dry, rigid types will.

What do you do with the leaves you’ve accumulated? There are several possibilities. Many municipalities, prohibit burning for the most part. Besides the fire risk, the respiratory issues for affected people can be life threatening. Raking leaves into the street, unless requested by the city for cleanup, usually results in clogging storm sewers.

Options remaining include composting, using as mulch, tilling into garden and bed areas, and hauling to the city landscape recycling dump. There may even be some private collection services that will take bagged leaves to a recycling center. Partial composting, and the subsequent use as mulch, is one of the best solutions. Simply construct an enclosure at least two feet cubed, place leaves in it, and cover the top with hardware cloth or wire laid on it and weighted down. The resulting much may be used next spring on flower beds, gardens, around trees and shrubs, or spread back on gardens or lawns.  

One thing to consider is removing the leaves from around the foundation of the house. The decaying leaves provide a hiding place or food sources for nuisance pests such as lady bugs and millipedes. The removal from directly around the house may reduce the number of these insects making their way into your home. A foundation spray of an insecticide such as permethrin will also reduce numbers coming into the home.

This will be the last regular offering for the year. Once again, I’ve enjoyed providing the material. If you would like more information on horticulture or other topics topics, please check out our website at http://web.extension.illinois.edu/lms/
