How to remove invasive honeysuckles?

I've cut them down - but they keep coming back. Several of them are against my wood fence, so I can't use traditional stump removers since they "burn" out the stump. These things kill everything else off in their path, including zoysia grass, leaving bare dirt. I have at least 6 more to deal with and already filled 15 lawn waste bags with them. They are volunteer plants and the Missouri Dept. of Conservation says to please remove these terrible plants. They are at least 12 feet high and wide - see the dirt underneath.

    Persistence is your friend. The ones you show haven't been cut down recently. Stump remover does not need to be set on fire. It will speed the decomposition process. Dirt underneath is the same as you would find with any tree or shrub. They block the sun and moisture from getting to the grass.

    Holy cow! I've never seen a honeysuckle that big! The ones I've seen in SE Wisconsin grow as shrubs. Looks like once you cut them down because they have large "trunks," the best way to get rid of the stump and roots underground would be to grind them out. I believe you can rent stump grinders and DIY if you don't want to hire somebody to come in and do it (no idea what it would cost in your area). Or, you could try using Epsom salt - I read about this recently and I might try it on an old stump I have that wasn't totally removed by a stump grinding some years ago. Link:

      Thank you for the information! We will try the epsom salt. These honeysuckle are not the regular type - they are an invasive species to the United States and grow more quickly than honeysuckle "vines" we generally see around here. These are over 12 feet tall and wide. I've cut out 4 already and have 15 bags of yard waste - I have at least 6 more to get rid of - they are "volunteer" popping up in unusual spaces.

    Get sine TARDON RTU. Cut the stem, pour on Tardon to cover right after cutting. Tardon goes to the root and kills the plant. Nothing comes back. After a couple of weeks you can just kick the remaining stub over. I've used it everything that I wanted to get rid of (even popcorn tree) and a little goes a long way. Only about $13 at our local co-op/farm supply.

    Cut it all the way down to the ground then cover the entire area with black plastic. Weight it down and leave it alone. Plants need light ,air and water...take it away and they should die. You can also call your State extension office ( university of Missouri) and ask how to get rid of it too. All states have a Master gardener training which is part other universitys extension office.

    That looks like Honeysuckle bush. It hides trash at vacant house property . I have been trimming it almost every year. I don't like seeing next doors trash they left over 10 years ago and City won't lift a finger.

    I've got 1 that planted itself in my yard also. Cut it to the ground! Put plastic (heavy, heavy plastic) all around it so it can't root more runners. Drill holes into any large trunks and fill with salt and cap. Cover all new cuts with herbicide or salt and cover it all over. Persist!
