I wanted to show you how I potted the Mediocalcar decoratum divisions. This species forms a mat and needs a short pot. It likes to be moist but does not like sitting in water.
I am using a 2 1/2-inch pot. These are also 2 1/2 inches deep. The first step is to reduce the depth and create an air space. For this I use foam peanuts (the "bad", non-biodegradable type). I use three or four, enough to cut the depth to about one and a quarter inches.
On top of the peanuts I put a layer of sphagnum cutting the remaining depth to about three quarters of an inch. I do this for as many pots as I have divisions.
Taking the cutting, I added about 3/4 inches of sphagnum up around the roots and placed this as a unit on top of the pad in the pot. To keep it all in place I cut a large paperclip to make pins and put one over one of the rhizomes. Now they can settle in to the pot and grow new roots. I can handle the pot without knocking the new division loose.
