If the stumps are already sprouting you may have trouble killing them now. When freshly cut, diesel coupled with any broad leaf killer should work when sprayed or brushed on the stump. I use diesel and remedy but I have the need for the 80.00/gal remedy. I find that diesel alone sprayed as a basel stem treatment kills many trees such as winged elm and youpon.

Does round-up work in your experience?

I should clarify that not all of the stumps have sprouted yet. The worst has been what I guess is called "Poverty Weed", that wispy, Willow-looking brush. You cut them off and they sucker twice as bad! Those and hackberries are of the greatest concern.

A drop of broadleaf weed killer applied full strength will kill sprouts and seedlings. You can use a stick dipped into the container to apply the drop to the new immerging leaves or the cut stem. I have better luck with it than with Roundup and from what I've read it is less toxic being a plant hormone that disrupts the growth of the plant rather than a poison. I've heard that some people use vinegar, especially a more acid form than that ordinarily found in grocery stores, but I don't have any experience with it.

I've drilled holes in the stumps and poured in gasoline then set it one fire. It was fun thing to do....

IMHO roundup won't work. It won't hurt to put some in the mix but not by itself. A broad leaf killer will work better. A TSC has 24D for less than 10.00 a pint. It would give the most coverage for the money.

I love Lou's idea, but I'm guessing the City fire dept. may not have a good sense of humor about it.

It sounds like a broadleaf weed killer is about the best way to go VS roundup. Is 24D the brand that seems to work best?

No offense to Lou, but ignighting gasoline anytime is very, very dangerous. Use diesel, it is less volatile.

As far as 2-4d being the best, no, it is not. It is probably the best for reasonable cost and availability. Dupont Remedy would work far better but at 80.00/gal it may be out of the normal price range for your application.

No offense. I burned a neighbor's front yard one time after my other neighbor poured gasoline but I didn't know he had poured along the ENTIRE length of the driveway. I was only a dumbass teenager but I couldn't resist and lit it on fire. After we put it out, 2-3 feet strip of lawn was burned.... oops. I was much more careful with setting tree stump on fire but it was taking too long so I hosed it out. It's not like I'd just go away because I was much older and wiser knowing anything would happen while I'm away...

My dad used to pick up a used tire every weekend, lay it over the stump, fill it diesel and catch it on fire. It would burn for several hours and slowly wear away at the stump. Of course, he lives WAY out in the country where burning trash is an accepted (even EXPECTED) practice. I think it took him a couple of years before that stump was charred enough to pull out with a truck and chain, and even that was a piece at a time. (Before, the tires on the truck would just spin)
