Best Herbicides For Buckthorn in 2022 (Buying Guide & Reviews)

Gardeners and farmers are really struggling with invasive buckthorn in their woods. To end the suffering, you need to take an action and that’s where the herbicides come into place.

The ideal treatment time for buckthorn is during Fall, while the sap is flowering from the roots and gives full access to the absorption of herbicides. Moreover, this “I’m taking over the land” kind of species keeps the foliage and carries on growing much later than plants, by cutting back the damage the herbicide will do to other species that got in dormant for winter.

Buckthorn is a widely-spread ornamental flower. The frequently found types are glossy buckthorn because of its shiny and actually beautiful leaves. 

In the US Department of Natural Resources, there is a list of herbicides that helps you control buckthorn and explains in detail if you use triclopyr or glyphosate (at a certain percentage).  

The Top 5 Best Herbicides For Buckthorn

1. Roundup Concentrate- Most Versatile Use

Everyone is familiar with the Roundup family and is very satisfied with the result, including me. 

It kills every type of tough leave with highly concentrated active ingredients such as 18% glyphosate (1.2 lbs) and 2% triclopyr (0.13 lbs) just as the buckthorn needs to taste in order to disappear forever.

Not only kills buckthorn as an invasive type of weed, but this herbicide also kills any tough weed in the grass, stumps, and other 200 types including woody brush and vines, Poison Ivy/Oak/ Sumac, Kudzu, and wild blackberry.

Roundup acts in 24 hours and the manufacturer guarantees that will result successfully. Plus, is 30 minutes rainproof and won’t wash away easily.

5. Fertilome Brush Killer Stump Killer- Best For Killing Stumps & Woody Plants

Fertilome brand owns a wide range of organic and chemical use to make the life of property owners much easier. The matchless price and quality will absolutely work on every weed type. 

I always say early diagnosis is always better and this time, we share the same opinion with the manufacturer because weeds on the lawn are best prevented with Fertilome. 

The brush and stump killer herbicide contains 8.8% triclopyr. It functions in cabins, fences, walkways, and even in noncrop areas.

For great results, spray the herbicide on the leaves thoroughly when they have stopped growing. The signs of working are wilting and yellow leaves between 1-6 weeks, so that means you’re doing good. Always check the forecast, if it happens to rain, then abort the mission because the effectiveness drops if 24 hours haven’t passed.

Use a hose-end tank and combine 8 to 16 tablespoons (4 to 8 fl. oz.) and 1 gallon of water. 

Why Should You Buy It?
The Fertilome weed killer is specified to kill stumps and other woody types in a short time period (1-6 weeks), it is basically a shortcut. The price is reasonable and it’s a shot.

How to Manage Buckthorn?

After you think the buckthorn is fully developed, adding herbicide to get rid of the plant or hand removal with sharp objects will do the job fine. Just spray 2% glyphosate and 1% triclopyr acid at the end of October after dormant. The manufacturer tells exactly how you should use the herbicide on the label. You have to act accordingly.

Buckthorn usually grows 6 inches in diameter and can be managed by basal bark treatment. The solution or oil in the herbicide should be sprayed evenly on the stem from 12-15 inches over the ground.

If the area is way too large, you need to come up with a multiyear approach and be consistent in the use of herbicides.

Does Buckthorn Have any Benefit?

It is believed that buckthorn is rich in vitamins (A, C, K) and protects the human body against heart disease, but nothing’s evidential.

With sea buckthorn, the case is a little bit different. The studies show that it drops joint inflammation. Joint inflammation for those who aren’t familiar is when the immune system releases chemicals with the signs of swelling.

Can Buckthorn Grow Near Water?

Yes, it is possible for buckthorn to grow somewhere near water. Water quality is the head of the department or the main cause. 

The Riparian zone which is the area between land and river can stop the spreading and it’s kind of hard to take over the place. 

Is Buckthorn Toxic?

Almost everything about the buckthorn is toxic, starting from the berries, stem, and roots except the leaves. The sap of the buckthorn causes skin irritation as well. At times, it is mistaken for blueberries and without identification, please keep the children away from it.

A Brief Summary 

I consider the weeds in general including buckthorn as glue, you have to wash your hands away with soap to get rid of the sticky-finger situation. The same rule applies to the weeds, and they are the most unnecessary and eye bleeding to see. 

Herbicides are the cure if you use the right amount such as described on the label and use a reliable brand.
