Ok thanks for explaining. It’s an old switch in an old house, if there is now ground wiring in switch box, is there a simple way to ground?
The Bx would have a green ground, if it does take a screw on the fixture and screw the the ground to it, and if not, not sure how to produce  a ground. Not sure if it's possible.

Some of the wiring is original wiring from the 50ís. Donít think they were so into grounding things back then...

I think you're a little confused. If there is a green wire (meaning it's MC cable) and the box is metal, it needs to be connected to the box as well as the fixture. If there is no green wire (meaning it's BX cable) and the armor is acting as the ground, you would have to attach the fixture ground to the box.

Correct, the MC I would ground to the box and the AC (or bx) I would have the thin wire or the bx acting like armor like you said act as a ground.
 
 Green to box and fixture ground to box as well/tighten around a screw if you like.

To attach a ground wire to a metal box:
If it is a relatively recently manufactured box, one or more of the holes in the back of the box is threaded for the purpose of screwing in a ground screw. Wrap the end of the bare wire or the stripped end of the green wire around the screw and tighten.
If the box is old, it may not have a threaded hole for grounding. In that case, use a ground clip, which holds the ground wire tightly against a side of the box.

Either way, I am not referring to the thin bare metal wire that runs through armored cable.

As that's made to wrap around the bx and stick in a bushing to avoid the wires from being pulled back into the bx and having the wires nicked on the metal shards of the bx.

So now I replaced my old cans with led retrofits. Is there any reason in the world to save the old cans or should they go straight to the trash?
If you don't care why would you comment?

The white pieces in the photo are trims, not cans. As for the metal pieces, I'm surprised you removed them. Would the retrofits not have fit if you left those metal pieces in?

 So my gardener removed some bushes today and in the process also cut out an outlet that was next to them connected to the fence, I don't really care  about the outlet because I don't recall ever using it I'm just nervous now that there is a buried live wire somewhere in my yard.

Should I be concerned?  Anything I can do aside from digging around and looking for it? (Something i'd rather not have to do)

Thanks

Yes, be concerned. If you think you know where the wire leads to, turn it off or disconnect it at the next junction box.

If the gardener cut some live wires with an electric saw I'm sure there would have been some sparks or something, my hunch is its a dead outlet.

But what if I don't know where the wires came from?

Good point but how would I know for sure? Maybe he just pulled really hard and it ripped

So I see this at the back of the house and I'm assuming the wires go from there and under the concrete to the the fence on the opposite side



How do I tell which breaker in the house is for this so I can turn it off?

Use a wire tester and a partner and flip the breakers one by one.

The cover visible in the photo should be covering fully insulated wires, where you wouldn't be able to use a neon tester or multimeter to contact the wires without damaging them. Instead, use the test device that makes sound but doesn't require electrical contact.

There is a light switch also that was for in-ground lights that are also gone, those wires are much easier to get to, would it make sense that both the lights and the outlet are on the same breaker?

Where's the electric coming from? Another outlet on the opposite end?
