Invasive English ivy

Asked March 6, 2018, 4:27 PM EST

I am waging war against English Ivy strangling trees. The vines are 2 to 5 inches in diameter. I can cut them with a saw but I also want to treat the cut trunks with an herbicide to kill the roots. What do you recommend?

Use a systemic herbicide containing glyphosate or triclopyr. Apply it immediately to freshly cut stems. Keep it off the tree's bark by using a barrier of cardboard or plastic.

Because the leaves of English ivy have a waxy coating, when spraying foliage you must always use a sticker-spreader added to the herbicide. And use a high concentration of the herbicide.

Thanks! I have an old ( 20+ years ) can of triclopyr. Is it still effective after that time?

No. Pesticides shouldn't be kept for more than two years. Dispose of the old product according to the label instructions.
