That'll work. Either keep mowing until it dies or drill a few holes and fill with herbicide. I take a sharp spade and peel the bark off underground to speed decay. It won't last too long, no herbicide needed.

I do have a pecan in the middle of my greenhouse that is covered with two layers weed barrier. It sends up shoots all summer with no signs of slowing down after 7 years. Pecan is know for rot resistant roots.

A fruitless mulberry outside also cut at ground level in January 2004 and also about 12 inch trunk, never sent up a single shoot.

Sounds good. Really didn't feel like messing with it. I figure cutting a bunch of the large roots near the surface would help reduce suckering. I'll just bury it now.

I keep all this cut fruit wood (the thicker branches). I figure it would be great for smoking meats.

I took out a peach roostock several years ago once I discovered it was a rootstock and the fruit would never be any good. It was probably about the same size as yours, cut it off flush with the ground, and it never tried to put up a single new shoot.

In my experience peaches don't recover when you cut into old wood- even if you left most of the trunk it would likely never send out recovery shoots.

I flush cut a Hall almond tree(peach x almond cross) grafted on red leaf semi dwarf peach root. The Hall almond was a nice tree, great blooms, but to crack just a handful took half an hour. Then they needed to be roasted, I'll buy already roasted almonds for $5 a pound. The red leaf peach root stock is growing back vigorously and will get a Gold Dust peach graft in the spring.
