Will post some later today--gonna be busy till late this afternoon, but here are some I frill cut late last fall just before the leaves turned colors.
I cut 3 slashes into them about waist or knee high, and with an old one gallon pesticide spray jug, squirted about 1-2 oz of 25%-75% Remedy/diesel solution mix into each slash. I made the slashes with a hatchet.
I did the ones on the right side of the ditch, but not the ones on the left side.
One that died during the winter and fell down--you can see the slash marks from the hatchet.
This is the very first tree I tried this method on and this is how NOT to do it. I made slashes all over the place, and it took 3 years for it to finally die. Make a series of slashes all around the circumference, but all in a line--not several one above the other.
This is a tree I cut down about 5 years ago, and it sprouted multi trees from the stump--these are the hardest to deal with. I actually made a ring around each trunk with a chainsaw in this case, and then squirted the remedy/diesel mix in. Graveyard dead.
Another. The slashes are visible at the bottom of the bare area. Bark fell off when the tree died.
This, is what I use: You need a jug and squirt nozzle that can handle the diesel. A Walmart type squirt bottle will start leaking right off the bat, so choose one that has been used for petroleum based products or get one that is rated for it. One hatchet (or machete) and one squirt bottle. That's it.
BE PATIENT!! Let the tree die--it takes some time for the herbicide to make it down and kill the roots. I have had ZERO luck doing this in spring and summer. Yes, the leaves will turn fall colrs and fall off, but the roots live on if done in spring and summer. That, is because most of the action in the vascular system of the tree is moving up--not down. I know that BrushBusters and herbicide labels say to do this when the trees and plants are actively growing, but that has not been successful for me with sweetgum and Chinese Tallow. 2 different State foresters told me they never treat invasives in spring or early summer--a waste of their time and resources.
For little saplings less than 3' tall, foliar spraying does work, but with little tallow and gum trees (using Remedy and 2,4-d) you will get only about 70% real kill rate, meaning 30 out of every 100 little trees will come back next year. You just have to keep at it with those.
No matter what you do, avoid the temptation of cutting one completely down when the leaves fall off. It takes time, whether foliar spraying or hacking and squirting, for the herbicide to get down to the roots--at least a couple of months.
IF you chose to cut a tree down--Cut stumps--spray them within 1 hr of cutting the tree down. Sap forms on top of the stump and prevents absorption of the herbicide.
Again--I have NO experience with Honey Locust--just Yaupon, fennel, gum and Chinese tallow. Yaupon is an evergreen and takes a LOOONG time to kill.
Foliar spray, I mix 1qt Remedy, 1 qt 2,4-d, and 1 pt of surfactant to 100 gals of water.
There are propbably better herbicides out there, but they are restricted use and I have to be very careful what I use because of the wetands I have and being next to a National Forest on 3 sides. I do not have an applicators lic, so cannot buy anything with picloram and wouldn't use it anyway.
Gotta run.
