I'll chime in regarding Magnolia. I have/had a 6' Jane Magnolia that was absolutely decimated by a buck in rut last fall. I thought the tree was a goner and because what is left looks very dead...So today I dug it out and put a Acer Japonicum aconitifolium in its place. Well as I dug it out I noticed a ton of sprouts on the magnolia from the groundline. So I'll put it up on the hill and see what it's got, give it a chance! Until the deer hit it again that is, sigh.

Well, I wish you good luck with your remnant. In my case, I was hoping the answer was no, the sprouts won't appear.... If I can get a thumbs down on the Leyland Cypress, I can still go ahead.

Finish it off with glyphosate (active ingredient in Roundup)? Seems the thing to do, if you don't want to have to dig out a stump.

I have been successful with Crepe Myrtles buy chopping out the stump but as pointed out, this also involves removing major root branches for at least 18 inches around the stump. For the three I've removed this way, glyphosate was tried first, and was ineffective.

drrich said "finish it off with glyphosate...." and that is in line with my answer. If resprouting is such a concern, an easy way to fend that off is with a tiny amount of strong herbicide-use either glyphosate or another animal named triclopyr-at the dilution rates listed on the labels for "cut-stump" applications. This rate of dilution will be much stronger than that used for over-the-top spraying of the same chemicals. All one need do is paint or daub right along the cambium or outer wood layer-you don't even have to coat the heartwood-so a truly small amount of material is required.
