Here's my raft project in the beginning stages today. I thought I should get it ready so that the plants can recover from mounting before I set them up in the tree for their permanent home.
I made the little lattice out of bamboo but didn't let it cure long enough, so found that the hot glue didn't hold very well. I augmented with zip ties. Next time I'll cut the bamboo sooner and let it cure in the sun so it's not so green and wet.
I'm thinking each plant needs a pad - or sandwich? - of coco fiber, just so the roots aren't completely 'out there'. Is this just my traditional gardener's aversion to seeing bare roots waving around in the breeze? These are all Bc. Little Lulu plants so like lots of light and sparing water. They will have regular misting but will be up in the breeze on a big ol' (about 1ft. diameter) live oak branch.
