Cactus

(Cactaceae)

Cactus

The cactus is native to desert regions in North and South America. This bugger stores water in its stems, allowing it to go a long time without care. This makes it ideal for those looking for an easy and decorative green housemate.

Size: between 10 cm and 2 metres, depending on the cactus species.

Care

Light: cacti like a lot of sun. Therefore, put your cactus in a bright spot in the house, such as a sunny windowsill....

Water: This succulent needs very little water. Water about once a month in summer and only once every two to three months in winter.

Potting soil

Fertilizers

PK booster

  • This nutrient is low in nitrogen but rich in phosphorus (P) and potassium (K). Exactly what a cactus needs. It promotes a strong cell structure and encourages healthy root development.

Cuttings & propagation

Cut or trim a firm spur from the cactus with a smooth cutting edge. Allow the tip to dry for a few days until a kind of 'callus layer' forms. Then put the spur in airy potting soil and place it in a warm place with indirect sunlight to avoid burning. Wait about a week before giving it a little water to allow the roots to develop first.
