This euphorbia is from the fynbos of South Africa and as such likes to go totally dry between waterings, making it a low-maintenance plant. If you see your Euphorbia begin to shrivel or lose firmness, your plant is likely totally dry and should be watered. To get good healthy growth your plant doesn’t want to sit around totally dried out during it’s growing season. Once it is dry water it.

This euphorbia comes from an area with summer rainfall and is actively growing during that time, when it is forgiving of overwatering errors. During winter dormancy it should be kept extra dry and will be intolerant of overwatering, though extra sharp drainage (pumice mixed half and half with cactus mix) will make this plant much more tolerant of winter rains. With this sharp mix you’ll need to water more frequently in summer.

Remember that if kept in a small pot your plant will want more frequent watering.

Growing Notes

As this euphorbia ages it will transition from colorful and smooth new growth to dull, brown and rough older growth. This is called corking, and it is totally natural. Think of this like an oak tree where the new shoots are shiny and green, but then eventually you get a trunk covered in rough dull bark. Often this is accelerated by humidity, especially when cold in winter. Occasionally when Euphorbia obesa has a growth spurt after corking over it will make a perfect green star at the tip.
Occasionally pups, but if the species is pure they are generally solitary.
