Tephrocactus articulatus is part of the Cactaceae family and its native range is NW. & N. Central Argentina. It is a succulent subshrub growing primarily in the desert or dry shrubland biome. These plants are slow growing segmented cacti that eventually reach up to 30cm, the segments are loosely attached to one another so be careful. Tephrocactus are in the subfamily Opuntioideae so be mindful of the glochids which emanate from the areoles.
Genus name is from the Greek tephra, meaning ‘ash’, this is in reference to the colour of this plants epidermis. Specific epithet comes from the Latin articulatus meaning ‘furnished with joints’, this is in reference to the segments of this cactus.
Light: Allow the plant to see the sun for as many hours of the day as possible; with a minimum of 5 to 8 hours. A south facing window is ideal but may still need to be amended with a grow light.
Water: Allow the potting mix to dry out completely in between waterings then water thoroughly. Keep almost completely dry in winter (watering typically every 2 months).
Potting mix: Cacti or succulent potting mix is ideal. You can amend our regular potting mix with sand, pumice or horticultural grit up to 50% to improve drainage. Re-pot every 2-3 years.
Fertilising: These plants are not heavy feeders, you could dilute fertiliser to half strength and feed monthly if you wish to give it a boost.
Temperature: 18-32˚C.
Humidity: Average home humidity or low humidity is fine.
Tephrocactus are non-toxic but spines and glochids are super irritating.
