[MAIPC] Ailanthus and Basalbark Treatment

[Marc Imlay]

Because the flow is up and down with this species  I have to hack an squirt all the way around, unlike Privett which I found only needed two hack and squirts.

I recommend hack & squirt, making axe or machete cuts around trunk and using a spray bottle to spray herbicide mix into cuts, now through end of year.  Tree will die with no sprouts and you can cut it down in winter or spring before it gets brittle.

Hi Everyone,

 

Tree of Heaven is a big problem in Reston. Due to the make-up of our open space, in many areas surrounding recreational facilities and homeowner property, we cannot leave dead looking standing trees for months at a time. Residents complain and it reduces the “curb appeal” that the Association is trying to improve. 

 

I would like your input on this matter. When applying Triclopyr in a basal bark treatment, how long does the tree need to stay before we can cut it down? (2 months? 6 months?) 

 

In certain cases, I think we’ll be forced to do a cut stump treatment instead. We typically use glyphosate at 20% on the stump. How problematic is this method with Ailanthus? I know it can be effective in killing the large tree but then we have runners to manage. 

 

Thanks for sharing your thoughts,

Patricia
