Stump grinding ganoderma advice

[onetruth]

I've taken down a big cherry riddled with decay fungi and want to grind out the stump. There are lots of very nice, healthy trees near by.

 

Should I take away all the grindings and refill with soil, or is it fine to leave them in situ?

 

Thanks.

Toadstool producing fungus such as Armillaria I suppose could survive, but personally, i've never seen any bracket forming fungus putting out fruiting bodies on a pile of grindings. It may still be there but i'd imagine a lot less infectious than when producing spores.

Armillaria is pretty endemic and usually gets the upper hand when trees aren't healthy or stressed. I think I've read a recommendation though to grind out as much as possible and remove.

 

Bracket forming fungi will have released millions of spores anyway, so probably unnecessary to do anything. Just my opinion.

30 years ago the curator at RHS Wisley wouldn't allow grinding, roots had to be removed and taken to a stump dump for burning.

That was when labour was probably a lot cheaper.

 

I'm not aware of any research and image it would be difficult to prove which of grinding -leaving,grinding-removing or digging was most beneficial. Too many factors involved.

It was done with a back acter.

 

This was the same chap that took in a load of leaf sweepings as mulch from the local parks department, he hadn't reckoned on the loading with simazine.

Sounds pretty pointless to me. You'll never get it all collected as bits fly everywhere when you grind. It was already there in the first instance so you'll not be rid of it? Stopping it growing on the stump is probably the best you can achieve.

As Gary said, wood-decay fungi are everywhere. Ganoderma spores are everywhere, as they're so very common (specifically Ganoderma australe, which is probably on this cherry). The other cherries are probably already colonised (to many different possible degrees) by this fungus as well if they are semi-mature or mature, though the fungus simply hasn't produced fruiting bodies on the other trees that can be seen. This doesn't imply the other trees aren't 'healthy', though that term is quite non-descript for trees. Is 'healthy' totally void of parasitic fungi, or are we running just by crown symptoms?

 

Grinding down the stump and taking out as much of the material as possible is therefore an exercise in futility. You're also removing a great habitat for many saprotrophic fungi that may make the cherry stump their home.

Not to mention stag beetle larvae if you are in the south.

They will find a new [emoji537], the surrounding healthy ones
