About Pincushion Cactus
Botanically, Mammillaria spp. is a slow-growing succulent in the Cactaceae family. It reaches around 15 cm tall and 20 cm wide at maturity, with evergreen foliage. Pink, white and yellow flowers appear in spring.
Where to grow Pincushion Cactus
Pincushion Cactus suits arid and semi-arid, Mediterranean and warm-temperate climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot. It also is a genuinely water-wise choice.
Soil & planting
Pincushion Cactus does best in sandy and free-draining soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Pincushion Cactus is very drought tolerant once established, so once its roots are down it needs little supplementary water. A feed in spring with a balanced fertiliser keeps growth strong. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Pincushion Cactus after flowering to keep it compact and encourage the next flush of blooms. Overall it is low maintenance.
Using Pincushion Cactus in the garden
Pincushion Cactus earns its place for pots and courtyard containers and a feature or specimen planting. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For a cohesive, low-care bed, pair Pincushion Cactus with other plants that enjoy the same very drought tolerant and arid and semi-arid climate. Repeat it through a border to tie the planting together and give a sense of rhythm.
Good to know
It is thorny — useful as a barrier, but wear gloves when pruning.
