What I have are six wrought iron candle stakes that I am going to use in the yard near the front or side sidewalk where they will be very visible for either tealights or little potted plants. I'm afraid somebody will steal them (neighbor got some of his garden stuff stolen a couple weeks ago).
I've been kicking around what to do for some time now while I worked to clean them up, prime them and paint with rustoleum. I thought at first to anchor them in concrete in a brick? Anchor them in concrete in a cutoff pepsi bottle as a form? Etc. Then bury or "plant" them.
Now I have decided the easiest thing would be to cut the top off a pepsi bottle part way, leaving about 6-8 inches (not sure about exact amount), and drill? a hole in the bottom, stick the stake end through the hole, clip it with something that can be removed but not while it's underground, under the bottle, and bury that. Those bottoms are tough and I can't cut into the bottom with my exacto knife.
What I need is some kind of clip that will grip underneath so if somebody tries to pull them up, they will meet with resistance from the weight of the dirt that will be filling the pepsi bottle. If I don't clip them, the stake will just pull out of the hole in the bottle and dirt.
With the latter method, I don't have to ruin my stakes by anchoring them in concrete or something permanent. It will be a nuisance if I want to move them or bring them in for the winter, but if it's not one thing, it's another.
Maybe somebody has a better idea with pvc pipe or something I wouldn't think of. Somebody suggested on another forum that I link them all together with chains and bury all that, but that would be really difficult for me, first the securing part of the chains and secondly burying all that mess.
