I'm wondering if there is something particularly funky about my house. I have white/yellow mushrooms that sprout from time to time in the backyard.
too much moisture from rains plus sprinkler systems. i water at 430 am 3 times a week for 7 per sprinkler setting, i dont have any mushrooms. i would suggest cutting back on your sprinkler duration& how often.
~~~I water on the same schedule- 3 times a week 3 am for 7 minutes and I am getting mushrooms in the lawn- Its not just the amount of water!! Its where the spores are lying dormant, its the extremely high dew point and humidity, warmth and yes water that causes a mushroom to grow.
