I got shrooms growing from the steps up to my deck.

These (oyster?) mushroom sprung from either the grout or the gap between the tile and grout on the steps going up to my deck. The deck is tiled with Saltillo but underneath is plywood and concrete substrate. My guess is that I’m gonna have to cut that tile out and look underneath to confirm that the wood has as much damage as I expect, but wondering if treating it with something and then sealing the gap again with caulking / grout would do it? I live in a relatively dry area, but we’ve had a rainy time of it lately. With hot dry summer coming wondering if that would prevent the issue from spreading? submitted by /u/elcubiche [link] [comments]
