I have a sweet gum sapling. Actually it's about an inch or a little more around. I don't know how to get rid of it. I've cut it down several times but have ignored it for awhile because I can't figure out how to completely get rid of it. It's in the edge of a bed a day lilies. Don't mind losing a few of them if I have to.

I am not familiar with the sweet gum, but if it is a suckering tree, you may have to just be diligent about lopping off the saplings that pop up. I have a grove of quaking aspens (lovely trees) that want to take over the world. I've tried digging down to really get to the roots, but they run horizontally from the grove itself and are nigh impossible to stop. So, I just snip them off below ground level with the loppers.

I agree with just keeping up with cutting it back. If you put a chemical on the sucker, it will travel through the roots to the main tree and the whole tree will die.

The main tree is at least 50 plus feet away. It's a hardwood tree. I'm not worried about killing some of the day lilies they multiply so fast.

If you use brush killer it won't kill the daylilies, it will only kill the tree. It's not formulated for fleshy plants. Same for what you would use on daylilies. Won't kill the tree, just the lilies. So the lilies that I assume you are secretly hoping would die, won't die.

So for the tree, just go to your local hardware store and get some brush killer for it.

Thank you so much!
