Austrian Pines with Poison Ivy #935177

Asked June 11, 2026, 10:49 PM EDT

I have several Austrian pines that have poison ivy vines growing up the trunks of the trees. What should be done to eliminate this problem? What would be the most cost effective way to take care of this problem?

Expert Response

Hello,

That is quite the mature poison ivy you have. Treatment can be determined by your overall goals.

Poison ivy is a native plant that is quite beneficial to our wildlife. Migrating birds consume the fruits in fall. It also is a gorgeous fall red color.

It can also be a problematic plant for humans when we encounter it due to the itchy rash that it causes. If this is growing in an area where you or others visiting your property may have a close encounter, then removal is an option you can consider. Wear protective gloves, safety glasses and use caution as you work. You can remove it by cutting out a 'window' in the base of the plant. A few inches above ground, make a cut in the plant trunk. Then make another cut 6"-12" above that. Remove the piece you've cut out. You can apply an herbicide labeled for poison ivy - you may need to read the small booklet at the back of the bottle if poison ivy isn't listed on the front of the label. Treat the cut stump with the herbicide. Watch for any sprouts during the season. If you see new leaves growing, treat those. The plant in the canopy can be left to die off or you can carefully cut it out, depending on how high into the canopy you want to climb. Use caution if you decide to remove the top growth as all parts of the plant contain the chemical that will cause a rash. Do not burn the plant as the smoke created may burn into your lungs. Be sure to wash clothes, gloves and tools immediately. This resource offers further guidance.
