Scientific Name

Common Name

Origin

Description
These spiky cacti are sure to grab attention thanks to their unusual appearance; their deep red and green spines stand out next to paler green stems, making them look truly formidable! Handle with care, and pop this cactus in a nice bright spot and it will reward you with its standout form and by really catching the eye!

Light
Euphorbia like bright light, and can cope with direct sun; choose a window that gets a few hours of direct sun in the morning or evening for best results.

Water
This cactus cannot cope well with having constantly-moist soil, so make sure it dries out totally between waters. If your plant is in a position with less direct light, be extra careful not to overwater it!

Humidity
This cactus is adapted to arid (dry) conditions so does not need a humid location at all. If it's getting dusty feel free to hose down to clean, just make sure it can dry out quickly.

Soil
Use a well-draining soil designed for cacti and succulents, usually a mix with added grit and sand. Repot every three to four years in spring as the plant grows.

Food
Feed every other water in spring and summer; reduce to one in three in autumn and winter.

Temperature
Average temperatures of 15-32°C are fine; make sure it doesn't get colder than 12°C in winter.

Pet-safe
No, this plant is toxic to pets and small humans, as well as having sharp spikes!

Sprouts Top Tips
If you notice brown discolouration on your Euphorbia's stems, check closer before you act; if it is soggy you may need to take cuttings to save it, but if it is 'corking' and the brown is more like hard scabs, this is natural and not a concern.
