Lawns are recreational areas, they add ornamental feature to the Home Garden. Lawns require right maintenance. They are also susceptible to many diseases. The most common lawn diseases are thread like, microscopic fungi and spread by means of water or air borne spores. Not all fungi are mushrooms but the vice versa is true. Mushrooms are fruiting body /structures of some kinds of fungi, whose primary function is to spread spores to create new colonies. Fungi reproduce by the means of asexual reproduction and release thousands of tiny spores through their gills into the open. Mushrooms are not a lawn disease; they are only a management problem.
The air, water contains millions of spores. blue meanie mushroom When the conditions are right, the spores germinate. They look like tiny threads and are called hyphae. When two or more compatible hypha come in contact they fuse together to form a network called the mycelium. Mycelium eventually forms into hyphal knot; the hyphal grows and develops into a pinhead. Pinhead grows and develops into mushrooms. Mushroom (fruit body) contains thousands of spores that are released into open. The cycle repeats itself and more and more mushrooms spring up.
Lawn mushrooms grow on decaying matter such as old mulch, animal waste and rotting tree stumps. Mushrooms found in the lawns are often formed because of underlying scraps such as construction lumber, dead tree rots or any other organic matter. In the newly laid sod, mushrooms may appear because of the frequent irrigation required for it to get established, it creates an ideal environment for the growth of mushrooms. The primary reason to get rid of mushrooms from the lawn is – to keep kids away from them and to enhance the beauty of the lawn.
Effective measures to control the mushroom growth are –
Reduce Irrigation – Mushroom growth is favored by moisture. Over irrigation or poor drainage lead can trigger mushrooms in your lawn.
Better air movement – Get rid of closely grown thatch and aerate the soil to enhance soil penetration.
Fertilize – Sometimes mushrooms growth can be rooted out by application of nitrogen fertilizers.
Manual removal – Spreading of mushrooms can be avoided by manually removing them as and when they appear in the lawn.
Cleaning – getting rid of pest waste, disposing the rotting mulch and having the old tree stumps grounded can make a difference in mushroom growth.
Fungicides – spraying of fungicides. It doesn’t do much good as mushroom seen is only a fruiting body and the fungus is under ground and not accessible to the chemical.
