Hello,
I have lived here (raleigh, NC) for 17 years and every year we have a crop of mushrooms in the autumn due, I am sure, to the watering that is done following the reseeding of our lawn. This has happened every year and varies in the amount. This year is by far the worst ---- we have thousands and thousands of these mushrooms in our front yard. In every area of it ---sunny, shady all over. What I am wondering is:
1. If I don't pull them will they negatively affect the growth of the lawn (especially in the Spring)? We heavily seeded this year and watered a lot and have a lot of beautiful new grass coming in. I have put a lot of time into all of this and don't want the huge numbers of mushrooms to retard or prevent growth.
2. Is there anything I can put on the lawn to prevent these fungii from growing? And if there is, when is the optimal time to apply it ---- before seeding, before the first freeze, after, etc?
3. What causes these mushrooms to grow? Is it just the heavy watering I did for a week and a half to get the new seed going or are there additional factors?
4. Will freezing temperatures cause them to die?
Any help/information/advice you can give me would be very much appreciated. Thanks so much!!
