I don't like glyphosate, it scares me. That's what's in Round Up. Since it
only works through foliage, I don't know how well it would do for the stump.
Hackberry trees are such an incredible pain in the ass. We have one, but it's
very large and shades the west side of the house. It is a very prolific tree,
to say the least.

Drilling the holes is a good thing to try if you have the patience. Instead of
sugar, I would say for this one time only to use a synthetic bag of the cheapest
and highest nitrogen fertilizer they sell. Probably Walmart brand, the higher
the first number in the ratio, the better.

Drill as large holes as you can. Then put the fertilizer packed into the holes,
cover the stumps with clear heavy plastic and occasionally water it and add more
of the nitrogen fertilizer. Eventually, the stump will die out.

They vary in size from 2" diameter to about 4' diameter. jfrost sent me a
link to the dirtdoctor.com. The site recommends either drilling & filling
holes in the stumps with sweets (sugar, molaasses, jams, buttermilk, etc) &
covering with a wet mulch, or using a stump grinder. I'll probably take a
mixed approach, dependent on the size of the stump. If you've got another
idea, I'd still like to hear it.
