It is a fast-growing and easy to cultivate cactacea. Here are our tips:

  • EXPOSURE: It Prefers a sheltered location away from direct sunlight, not too bright.
  • TEMPERATURE: It is recommended to keep the plant always above 8-10 ° C. However, if the ground is well dry it can tolerate short frosts.
  • WATERING: Water regularly every 4-5 days in spring and summer, but be careful that the soil is dry before proceeding with a new wetting. Suspend completely watering in the winter.
  • SOIL: Use a standard soil for cactacea enriched with a little peat.
  • CONCIMATION: Concimate once a month during the vegetative period with a rich product in nitrogen and microelements.
  • REPOT: The rapid growth of the plant may require either the annual repotting and, given the particular plant growth, the preparation of tall but thin stem supports.
  • REPRODUCTION: The plant reproduces either by seed and cuttings. Usually, however, the branch cutting is used for the simplicity and quickness of this method. Plants born from cuttings tend to flourish much earlier.
