I am amazed that there are problems with Pleiospilos Nelli.
I have been breeding these plants for years they are incredibly robust. However!
They are succulents mainly from the Karoo Desert in South Africa. They are pretty cold hardy even to freezing a few times.
You should never overwater succulents from this region as they dont really have a 'water stop valve'. They will eventually split and burst. Always use a porous pot and gritty compost. The roots must be kept watered in the summer in order to flower (unlike the other species). That doesent mean plant them in a pond! Watch the moisture ring from the bottom of the pot and water lightly when dry. Remember why these plants are succulent. If humans are flooded they get upset too and have to claim on thier insurance!... read more

I've had this plant shipped to me by TWO different nurseries and both plants died within a month. I know it's not the nursery because I used a different nursery the second time, so I believe that the combination of shipping and not being fully prepared to roll out the red carpet for it (as was made clear by the other person that posted) caused me to fail to keep it alive. Although a pretty plant, I will not get this one again, unless I try from seed.

This is a plant that one needs to follow its needs with discipline. Unlike many mesembs it doesn't do well if watered in summer.

Very light early morning misting begins in mid-Dec. If the plant responds positively to the misting then increase the volume of mist.

Continued positive response would call for very light watering. Planting medium must be very porous, light of organic rapid draining. Best to never deluge plant. I use pure water or rain water so that there is no mineral buildup on the leaves or in the soil. A little orchid bloom fertilizer in early Jan each watering.

A most rewarding flowering occurs in early February.
