Observe
Chocolate trees, I’m not so much growing them as slowly killing them, but they’re still alive and I have high hopes.
On the left is an Inga feuillei (Ice Cream Bean). It’s very happy, growing lots of little shoots and a few big ones. I bet it would make adventitious roots, eh? Quick and easy propagation if so…
I enclosed a metal shelving unit with greenhouse plastic, put a heater on the bottom with fish tank full of water and a towel hanging down into it to make a simple swamp cooler to modulate the heater and increase the humidity. It worked really well until the towel dissolved!
