root rot on Greenovia
Quick answer
If your Greenovia has root rot, the most likely cause is: Basal-stem rot in Greenovia and other Crassulaceae rosette succulents closely mirrors Black rot and is associated with foot damage, excessive watering, or growing the plants too cold, conditions that let the stem base blacken at or just below the soil line because the rosette-forming Crassulaceae tissues cannot outpace the decay once it starts.
Start here:
- 1. Take clean cuttings from above the rot line, dust the cut surfaces with sulphur powder, and allow them to callus before setting the pieces to re-root in a fresh, well-drained gritty mix.
- 2. Re-pot the parent stock into a drier, lower-nitrogen compost with extra crocking and charcoal chippings, and hold back from watering until new roots have formed.
