The stems of a few of my succulents started looking dry and then they started to look shrivelled and brown. I was quite concerned. How would the succulent live if it could not get water from its roots? I did notice that there were some aerial roots above the shrivelled stem which would be the succulents way of trying to survive the lack of water it was receiving from its original roots in the soil.
Why did the stems shrivel?
This is ‘not‘ root rot or in this case ‘ stem rot’. Root rot on a succulent is black! and there is no sign of dried out stems when a succulent has root rot. This is due to the succulent having too much heat and not enough water for it to cope. Normally it would be the amount of heat – ie high temperatures. Succulents like sun with lots of air flow but some do not cope with high temperatures. ie 38-40C/100-104F. It may cope with a few days of high temperatures with the right amount of water but ongoing high temperatures with no water and the succulent’s survival tactics will kick in.
Will my succulent survive?
As in the case below, the stems have all shrivelled and the separated stems have put out new aerial roots in attempt to survive the heat. A sure sign it is willing to survive!
What can I do to save my succulent?
Firstly, do not panic! The reason we all love succulents is because they are amazing survivors. Cut the stems above the shrivelled part and replant into a new pot or a different spot in the garden. Move the pot/plant to a position with a bit more shade. Even if the stems do not have any tiny white aerial roots the plant will still grow some new roots in the soil and live on. Wait about 1 week before you water the new cuttings.
Some succulents do require a little more water than others. However, moving the succulent to a shadier position will most likely cure the problem. If you move the plant to a shadier position AND increase the water then you may then over water which will then cause root rot. So try the shadier position without adjusting the water first. If the stems shrivel again (in due course) then you should water more regularly. Some succulents do require more regular watering than others.
So why have the stems of your succulents shrivelled? Basically; to let you know that they are not happy and to do something about it!
