Concerned Neighbor - plant growing through fence

[Claire Peterson 3]

Hi everyone, 

A woman in Norton Shores contacted us through our MISC facebook page about a plant that has started to grow from her neighbor's yard and through their fence. She was wondering if it is Japanese knotweed. Below are images she sent.

Four of the images are indeed Japanese knotweed.  The fifth (with flowers) is an invasive honeysuckle, likely Lonicera tartarica.

Killing knotweed on just the messenger's property likely won't work, as it shares a root system with the neighbor; they will need to work with their neighbor to manage the whole stand together.

Thanks so much Katie, I will pass this information along to her.
