We do. Mushrooms this time of year are pretty normal, especially in over-watered lawns, after lots or rain, or during humid conditions. Common mushrooms are part of a harmless fungus that starts under your turf, breaking down organic material into nutrients your lawn can use. Since most mushrooms in your lawn are a sign of a healthy ecosystem, it may be best just to leave them alone. Aesthetically, they may not be very appealing to look at. Or you may be concerned with children and pets being around them.
If you want to get rid of them, simply just rake them up, or give the lawn a quick mow. Something to consider are watering habits. Although watering habits may not always prevent mushrooms, you should always water established lawns deeply and infrequently and only if rain has been scarce. Light irrigation promotes shallow rooting, non-drought hardy turf, and encourages crabgrass. Newly sodded lawns require water one or two times a day while newly seeded lawns will require water two to four times a day. Most ESTABLISHED lawns in our area will need from 1 – 1-1/2 inches of water per week. In drier conditions, the mushrooms tend to go away.
In extremely dry conditions watering your lawn anytime is more beneficial than not at all. However, the most ideal time to water established lawns is 4am – 8am. Although this is not the most convenient time to water for most of us. The second best time to water is 8am – Noon. Try to avoid midday waterings. Contrary to popular belief watering your established lawn in the mid-day sun does not cause turf to burn. However, a disadvantage to mid-day watering may include loss of moisture through evaporation, making it difficult to thoroughly wet the soil.
