The name of this particular cactus derives from Greek and literally means “nipple cactus”, to identify the particular shape of the large and pronounced tubercles placed along the numerous ribs, on the top of which large downy areoles protrude.
It is a spherical and solitary plant, highly appreciated for its perfect symmetry, as well as for the considerable size that adult plants can reach: its grandeur and wild appearance will give your interior an extreme desert charm!
The genus Thelocactus includes 15-20 small spherical or ovoid cacti, usually solitary but sometimes forming clusters.
They have been introduced in Europe in 19th century and then they became very popular among succulent enthusiasts for their beutiful, big flowers and their resistance which make them easy to cultivate.
- Put your Thelocactus under direct sunlight.
- Keep it above 4°C and shelter it during the winter.
- Water every 3-4 days in spring and summer, decreasing the frequency in autumn and stopping completely in winter. Make sure the soil is well dry before proceeding with the waterings.
- In nature it prefers calcareous soils. A standard compost for cacti can also be used for cultivation.
- Fertilize your Thelocactus twice a year, in early spring and early summer.
- For a healthy growth it is advisable to use pots just slightly larger than the diameter of the plant. Since, however, these cacti have rapid growth, repotting will probably be necessary every year.
