How do I kill mushrooms....Pushing up my driveway!!?

Question

I have a problem with mushrooms pushing up parts of my driveway asphalt and it's actually lifting some parts up a couple fo inches or more, causing damage and creating a trip hazard. is there any commercially available fungicidal product that anyone has heard of. I'm also looking into any home remedys. Thanks for reading!

Answer 1

If it looks like you can actually 'push flat' the parts that have raised and are willing to put up with the crack; I'd suggest first applying in the gaps something like vinegar/salt/water mix (bascially change the conditions to become unfavourable for the mushrooms, think preservate). Then flatten it back down to make it safe.

Although by the sounds of it this would only give you at best a short term temporary solution - as the mushrooms must be growing off something underneth, which will rot and collapse, so later on you could be left with a pothole to deal with..

Answer 2

I suspect you have rotting tree stumps or some other kind of wood underground, and your driveway is sinking in spots rather than being pushed up by mushrooms.

You can kill them but that doesn't stop new ones from pushing through. You have to tear up the ground and see what's rotting under there, causing the fertile conditions that mushrooms love.
