I have a zamioculcas zamiifolia, aka "ZZ Plant" & I think it is bursting out of its current home. When I purchased it a few mths ago, it was in a non-draining glass container with, what appear to be, tiny purple glass beads @ the bottom, then fibre (coconut?), topped by very soft, shaved bark. This was how the grower supplied it. The care instructions said to repot in 12 mths, but already the bark is way above the top of the container, as if the tuber is
growing & pushing the contents out of the "pot". The plant is thriving at the moment.
Does anyone know what sort of potting medium I should use?
I have seen larger plants in normal potting mix, but don't if that is the way to go. The grower is in our area, but has not answered my e-mail asking him for his help
even though I said I wanted another of his plants!!! Ordinarily, re-potting would not faze me, but this plant is, sort of, different. Any advice would be much appreciated
