mushroom compost

My husband purchased mushroom compost to use in our flower beds. Our property slopes down into our neighbors lawn. Our neighbor is now getting mushrooms in their lawn. A lot of mushrooms! Our neighbor never had a problem with mushrooms growing in their yard until after we started using mushroom compost. Could the mushroom compost we're using be causing the mushroom growth in our neighbors yard?

Doug says that it's technically possible that there were mushroom spores on the compost but don't quote me on that. The mushrooms should have been picked before they produced spores but... (way too many variables here to guess)

And it would have had to flood in your yard to wash this material down into your neighbours property. And you should have the same problem.

So if there were spores and if there was a ton of rain to move them down there and if you have the same problem, then I'd say it might have come from the compost.

But if you don't have a similar problem... then I'd suggest that all the spores couldn't have washed down so...

But it's certainly not common to see this. As for mushroom compost, you might want to let your husband see the article I wrote about this material right here.
