re: Honeysuckle- How invasive is it?

Just be sure you keep it knocked back or the power company could very well do it for you. It'll depend on the utility company and how brazen they are. The bigger ones are pussies about things, but the smaller co-ops will go scorched earth on your arse- all the way up to the meter- if they get to feeling froggy.

They frown on planting any sort of climbing and/or invasive vegetation on their field assets and infrastructure, but especially so with their power poles. I built a privacy trellis around my meter that also hides my natural gas meter and doubles as a garbage can storage hub. My wife loves it because she can just chuck full bags over the top and if they miss the can, oh well, out of sight out of mind.

One time in LA we had to go in on an emergency type job for Entergy where an OC had been fired for doing his job, aka nothing, and vines had grown up nearly all of their assets and were causing power outages. Although it's an extreme example, that's why they don't like it, but we'd see it daily in isolated incidents. So PSA, never ever plant a beloved tree or anything else that can grow up (or on) to minimum approach distance in a powerline right of way or it will eventually have to be dealt with.

(It always amazed me how many folks (especially in Tennessee) thought that big transmission line right of ways were good places to farm pot. There's a guarantee that folks will be coming through every couple years to spray herbicide and trim trees, followed by a helicopter audit. We would just keep on rolling, but I'm sure the residual herbicides the crews sprayed eventually killed the plants.)
