Basal bark works. Applying brush herbicide with a mineral oil carrier allows the herbicide to be sprayed on the bark. The mix absorbs into the basal cells of the bark where all the action occurs in a tree or shrub. Hence the term, basal bark herbicide application.
Below is the expensive Birchmeier backpack sprayer. Many people use these because their seals hold up better with the mineral oil carrier. Elsewhere on this blog I have written about these packs. There may be other packs that do as well. Let us know if you have a pack you have time tested.
Below are some of our paint roller applicators sticking out of the buckets. In the bucket is an inch of basal bark mineral oil herbicide mix. You have a 5 inch long paint roller on a handle cut to about 30 Inches. There is a screen to roll back and forth on to get rid of the excess solution. Make sure roller has stopped dripping! Then take roller to your honeysuckle and roll the solution on the stems. This works.
The advantage of basal bark herbicide application:
- It is several times faster than cutting and treating the shrub.
- It is quiet and safer than running a saw.
- It works as well as cut stem treatments.
