dead peach trees in hugelkultur beds?

Hello I am new here and can see that there is a lot of good info. so I have a question.I have an organic peach orchard. Over the last two years I have lost most of my already aging peach trees due to lack of rain.I want to replant in Hugelkultur beds but was wandering if I could bust up and us the old trees in building the beds? Peaches might not work because your are not suppose to replant them in the same location but other things might like apples blackberries figs etc, what do you think?

If any of the peach wood is still in good condition you might think about cutting it to sell to wood carvers. Otherwise I think it would be great for hugelkultur!

I have not thought of the wood being off any value for wood working but I will consider that. But I have a lot of it, at least 500 trees that need to come down. We have lots of hot dry wind and long dry spells.

One thing I am considering is bring in a ditching machine and digging three foot deep trenches then fill them 3/4the way full with the busted up dead peach trees, manure and hay. Then plant new trees next to that. Would that conserve moister better than a raised hugelcultur bed? What are the pros and cons?

Does anyone have any links to info/videos that would help me?

I have had thrilling results using buried wood in my kitchen garden; during the past two years of drought I believe it saved my garden, which used to die during the heat of summer even with irrigation. The young apple trees I have in that garden doubled their growth rate after I buried wood around them and I'm convinced not to try planting any more trees without burying wood near them.

There are photos in my projects thread.
