I have repotted my tropical hibs in regular soiless container mix. Not much else to say about care other than being aware that any sudden change in their environment (including repotting as well as amount of light, water, temperature), is sure to cause them to yellow their leaves and drop them. But do not dispair, they will inevitably grow new leaves that will sprout along the bare stems and that are more adaptable to those changed conditions. I fertilize mine with whatever I have around, although I will try to do an Ironite (or equivalent) addition in there during the growing season.

They can grow in full sun (but would need more water) or part sun and still bloom pretty well. They bloom on new growth, which has to mature for flowering to take place. They can also be pruned to shape.

Indoors, just watch for spider mites and make sure they get enough air flow and some humidity around them.

I bought a number of these and have them in a small stream that connects two ponds that I put in. They are root bound. SHould I leave them be when I bring them in for the winter or repot them at that time?

Can I take cuttings now?
