Does this go for cut stump treatment with herbicide as well?
Thanks
There's probably other guys that can answer that better than me. I'm still trying to learn more about stump treating since I've only been actually treating cuts for a couple years. Grape vines are one of the invasives I've battled for several years now. I used to just cut them and not treat...BIG MISTAKE! One 2 " diameter grape vine will turn into a dozen little vines if the cut isn't treated and it becomes very difficult to control it in the future.
But in late winter/early spring, sap runs out of the grapevine cuts like a trickling faucet. I'm blown away at how much sap comes out of a grapevine in the spring. I also wonder what is contained in that sap that runs onto the ground after the cut. Are there beneficial nutrients that are scavenged from deep in the ground? Or are there allopathic chemicals that inhibit growth of desirable plants? And I'm not even sure how the herbicide could get to the roots because of the sap flow. Seems like the vine would flush the chemical out. But apparently, some herbicide does reach the roots because I've been getting a decent kill, but not 100%.
Oriental bittersweet is another P.I.T.A. vine that I recently realized I need to fight. I now treat every single cut of OB and I still get some newly emerging, adjacent vines. I don't know if it's a new plant, or a sucker from the other one that I cut and treated.
IMO, vining plants are among the hardest to control because their root structure is huge and complex. If you cut a vine, TREAT THAT CUT OR DON'T CUT IT UNTIL YOU ARE PREPARED TO TREAT IT. Only cutting without treating just turns one problem into dozens of suckering problems.
I've also started treating black walnut and black locust with the same results...good, but not 100%.
95% of my cutting of invasives is done during March and April. I can't say if that's the best time or not. Maybe fall is better?? I don't know. But I have a hard time disturbing my property just before or during bow season.
