This has got to be the balliest, most entertaining thread I've read on here. As weird as it seems, I've actually considered the same thing, growing them in the tree tops. I have some ideas that might make it easier, safer and more stealthy. (1) camo paint your pots. If you use green pots, get a can of black paint, cut a branch with leaves and use it as a stencil and spray around it. It doesn't have to be perfect, just something to break up the shape. (2) What about running a lightweight cable between two trees with some pullies anchored at 1' spacing thru which you run parachute shroud line (OD Green). You could pull the babies up for their sunbath, let them down to check on and water them. (3) What about another tree with leaves more similar to the pot plant, sweet gum for instance. Pine needles contrast too much with the shape of the pot leaves. I know it's being picky but it's just stealthier.
