Crassula falcata Buddha's Temple

The pot of two large and winding crassulas, and a small one which was just a piece that had broken off last year, is growing well and I feel that there may be some flowers this spring.  There are some bare patches on the lower reaches but lots of nice healthy side shoots.  Once it has flowered, I think it will be time to regenerate by taking lots of cuttings from these side shoots and ditching the two older plants.  I think these plants are about three years old, since they are from cuttings from the plants which I 'refurbished' last time when I posted about them flowering in 2014.  I noticed that some well organised gardeners write the date of propagation on the label...I must get organised!
