Cactus e Dintorni

Habitat: Northern Argentina, Bolivia.
Description: a dwarf genus with short ribless stems, spiny tubercles, beetroot-like roots. Flowers are borne from April to September. In the wild they grow in fissures among rocks and other humid sites. They self-pollinate.
Soil: basic mix or 60% sandy soil, 20% agriperlite, 20% pumice stone.
Location: choose a bright, warm site with indirect light.
Temperature: grafted plants are able to withstand a minimum of 6°C (43°F).
Water: average; increase the frequency during the growing season. Spray with water in the warm summer evenings.
Cultivation tips: seeds are very difficult to germinate; they’re slow-growing plants. It’s a frequent practice to graft them on Myrtillocacus geometrizans or Hylocereus undatus, although the latter has a tendency to become swollen thus spoiling its appearance which is compensated for by a good seed production. They’re prone to mealy bug and spider mite. Seedlings usually need protection against the larvae of the sciara fly (tiny white worms) that hatch out in humus-rich soil if not previously sterilized.
Main species of Blossfeldia: Blossfeldia liliputana, sin. Parodia l.; Blossfeldia fescheri; Blossfeldia minima.
