My E. Purpusorum has begun to shrivel its bottom leaves and just by touching the plant it came-off. The roots seem to have died, but I still have a chance to root the stem. This species seems difficult to grow in my area, as I lost anoter E. Purpusorum last summer.
My challenges - Local climate and locally-used potting soil. First, I have a link to show you the climate in my city. Values are average. Local nurseries potting soil is not sufficiently draining, but global warming has been on my side for a while. I potted-up few Echeverias into a better draining mix. Most have grown a bit and then flowered. I had to take advantage of the relatively warmer winter, because my pots sit in the open and are not protected from excess rain. My mix with much added Perlite seems to solve the problem.
The sick plant - It is now February, and temperatures are only now reminding me of true winter. I expect temperatuers to rise in March. My E. Purpusorum can be trimmed to take-off the dead roots and any parts of a rotten stem, if there is. my question: It is too cold and wet to make new roots?, Should I let the cuts callus and wait till mid-to-end of march to re-root it?
