What would cause mushrooms to grow so soon in newly laid sod?

Mushrooms in Newly Laid Sod

• It could be a couple of things. The mushrooms could have been under the ground you laid the sod on, however, if you have not seen mushrooms in that area in the past, that's probably not the cause. There could have been mushrooms growing on the farm where your sod was grown, though most farmers are careful to watch for and eliminate them. The most likely explanation is that the person installing your new lawn (or yourself) purchased soil or mulch that contained mushrooms to help fortify the ground before installing the grass. Your water and fertilizer simply helped to welcome them to their new home.

• It could be old dead tree roots rotting if you sodded because of a tree removal.

• Don't worry so much about mushrooms in your lawn.

They may form beautiful fairy rings of darker grass. Consider them a blessing. Learn what they are. There are many lawn mushrooms that are edible. You may have some good ones to eat. You will never be able to kill them all, so enjoy them and look forward to their appearance every year. I collect and eat 5 different species from my own yard each year.
