We had a question from a client about mushrooms in their lawn and while Matt handled her call, I did some research. Here is what I learned.
Mushrooms are truly unique organisms, and their ability to recycle agricultural wastes, tree stumps, and other decomposing matter is usually not fully appreciated when they are doing this right in the middle of our lawns.
We are talking about the mushroom-producing fungi that are lawn management or nuisance problems but do not necessarily cause lawn diseases.
Mushrooms, sometimes called toadstools, are the fruiting structures of some kinds of fungi, others found in lawns include inky caps, puffballs, stinkhorns and bird’s nest.
Most fungi in lawns are beneficial because they decompose organic matter, thereby releasing nutrients that are then available for plant growth.
Lawn mushrooms feed of decaying matter such as:
Construction scraps of lumber
Rotting tree stumps, roots
Old mulch, Animal waste
The more food sources for the fungi in your yard will pretty much ensure the presence of lawn mushrooms in your yard.
Picking mushrooms, puffball, stinkhorns, or others after they appear may prevent the spores from spreading to new sites. The primary reasons for removing mushrooms from lawns are to keep them away from children and pets (because you don’t want them eating them by accident) and to improve the lawns appearance. When the food source is greatly reduced or eliminated so are the visible signs (mushrooms) of this organic process.
Here are some means of control:
Reduce irrigation – many mushrooms are associated with over-irrigation or poor drainage, and mushrooms tend to go away as the soil dries out. So water your yard less and at the appropriate times.
Better Air Movement – removing excess thatch and aerating the soil to improve water penetration may help in some cases.
Fertilize – you can sometimes eliminate mushrooms growing from organic matter by applying nitrogen fertilizer. This helps, because fertilization speeds up decomposition of organic matter. |
