How do I get rid of tree root fungus?

Question

I have a big, old, oak tree in my front yard. There's a fungus that keeps growing periodically on it's roots. I've been taking it out with a weed whacker, but it keeps coming back.

Answer 1

I don't really know which fungi is attacking your oak, and there are several to choose from, so here are some links that my help you identify the problem. The information contained within those pages also gives tips on management and eradication of the problem.

Answer 2

This could be Honey Fungus if it is then I think you might lose the tree. There is a way of telling if you have it. Lift a small piece of bark off just below ground level --- fungus can be seen as flat plate like white growth which smells of Honey. The Mushroom clumps have long stems,honey coloured and smallish caps with gills which produce the spores. I hope you don't have it because it spreads by runners underground. and seems to go from tree to tree. I know because I have lost quite a few to it.

Answer 3

If I were you, I'd stop worrying about the fungal growth on the tree roots. It's possibly a mycorrhizal fungus, which is actually beneficial to the tree. It helps transition nutrients to the root system. If not,it is just a shelf fungus that is not harmful to the tree. If your really concerned, consult a certified arborist to check it out.
