How to kill nightshade when it is growing up through a large shrub and can't get to the roots? I was away for a couple of weeks and it had grown up through the shrub and across my small stoop. I had to cut it to enter the house. Later I identified it as nightshade and thoroughly washed my hands and arms.
If you are unable to dig up by the roots, then you will have to use an herbicide that contains glyphosate, which is discussed in the following article:

My neighbor and I share a chain link fence. This summer, a vine appeared with small, purple flowers which eventually turn into small red berries. It grows fast, first using the fence as a trellis and now spreading about 3 feet in all 4 directions. We don't know if it's a weed or a plant. Any ideas?
This is most likely Climbing Nightshade.
It is a very invasive plant. Weather it's a weed or flower can depend on the garden and gardener!

The plant grew as a seedling in a pot of chili plants. Seems the seed blew into the pot. The leaves look similar to a tomato plant with soft white hairs on the stem but it does not smell like tomato.
It does look like a Tomato plant leaf, if it does not have the typical smell, it is likely something in the Nightshade plant family.

I have one of these trees and it is approximately 10 years old. This is the first year that I hardly have any leaves on it. She looks terrible and her stalks where the leaves grow are like totally brittle and dead. She has growth and some new leaves (very few) on the very ends of the stalks. I tried cutting some of these out and nothing happened so now she sits with 1/2 of her thinned and 1/2 looking dead. Please help, I love this tree and this is the first year I have had problems with it. Thank you for your help.
This shrub does need consistently moist soil, but never soggy.
Also if the plant had any winter stress, too cold of temperatures, it could be effecting it's health.

I have a beautiful, healthy bush and would like to know what to do to start a new tree for next spring? I live in zone 3; we have the perfect growing conditions here in our hot summers! It's in a big pit and is about 4' tall and very happy!! What should I take from this plant to recreate next spring(2018)?

What type of bee (bumble bee?) are contantly humming about the blue potato bush flowers, mostly touch and go - so difficult to photograph. But let me try and upload photos - big and 2 white stripes on the back.
I'm not familiar with the insects of your area, but if you take this photo to your local extension service then they will be able to tell you more about your native species. Here is the link to find the closest one to you: https://www.gardeningknowhow.com/extension-search/
I have developed an allergic reaction of burning, itching blisters if I handle woody nightshade; so I cannot pull it up by the root. I don't want to use a chemical poison in the garden. Is there a natural product that will kill it?
