    To control re-sprouting of aggressive trees and shrubs (hawthorn, holly, etc.) as well as larger-diameter aggressive vines (blackberry, wisteria) there is a non-chemical strategy that works, a chemical strategy that works, and a very common chemical strategy that doesn't work.

    The non-chemical strategy Every time it sends up a shoot, prune it off. This strategy basically involves starving the plant to death: it costs the plant energy to send up each shoot, and if you cut off the shoot before the new leaves can start feeding new energy into the plant, the plant loses. But if you forget it, and allow new leaves to recharge the plant's resources, the plant wins, and you lose, and the clock starts over. success with cutting it back to the ground several times in the growing season for several seasons in a row. so long as you cut it back just after it leafs out in the spring and it's small or weak there is a chance it will die. If it is over a small area I’ve also used a shovel or a grubbing axe to cut the roots of the smaller ones to set them back. Unfortunately the only sure fire way found so far is with a lawnmower

    Removal of tree and continual growth----The chemical strategy that doesn't work is to cut the plant, then go back later and treat the stump with an herbicide, even a strong or concentrated herbicide. Woody plants, it turns out, are very good at "compartmentalizing" a problem, even a very serious one. Within seconds, literally, of being cut, a woody plant or vine seals up the cut areas with residues that block the intake of the herbicide toxins into the remaining parts of the tree or vine.

    The chemical strategy that works is to apply an appropriate concentrated herbicide IMMEDIATELY upon making the cut, before the plant has the (minimal) time it needs to block uptake via the severed circulatory system. (One published study says the window of opportunity for blackberry vines is 15 seconds; another author says that window is only four seconds!)

    Recommended herbicides include a 20% concentration of glyphosate (start with the concentrated bottle that says "41%" and create a working solution by diluting 1/2 with water). Or use an 8% solution of triclopyr. In either case, you are starting with a bottle marked "concentrate", not with a pre-mixed spray bottle.add food coloring so you can see where you are applying/spraying it. In the bad old days the solution was applied with a small paint brush; today the weapon of choice is a cheap household hand spray bottle. And of course you should be wearing rubber gloves and eye protection.Round-Up works best.

    When using any herbicide--or any garden chemical, even those marked "organic"-- ALWAYS READ AND FOLLOW THE LABEL INSTRUCTIONS AND WARNINGS. In addition, note that herbicides should NOT be used when air temperatures exceed 85 degrees, or will exceed that temperature in the next 8 or 12 hours. In hot weather, herbicides can evaporate and form a small toxic cloud that can drift for hundreds of feet. here's more poison ivy but same basic info.---

    Round-Up.......cut if off,wearing mask & gloves and long sleeved pants shirts remove tops put in garbage bags( thoroughly wash clothing shoes tools anything that you have used to remove the tops;get 2 gallon pump sprayer(not a back pack don't risk leaking solution on your back) buy concentrate Round-Up add food coloring to it(so you can see where you are spraying it) as soon as you see new leaves growing on stems spray them heavily with the Round-Up. It is absorbed into leaves them stems then kills root systems. Round-Up works best when plant is in vigorous growth after being cut off & new leaves are emerging.Keep checking for new growth and spray thru out growing season.Depending how big the area is it may take a few weeks to get it all. Put spray nozzle down onto leaves when spraying & do not spray in wind or breezy conditions;use gloves;do not walk or get in wet solution. Follow the safety instructions on container they are & have always been on the container for a reason.

    I would use poison ivy spray, it works and gets the roots. Spray it on, and don't remove the vines, let it get down into the roots and kill from the ground up.

    Hi Karen, you could try this one, we use it here. It has no chemicals, so sometimes we have to spray twice but it's worth it to us.
