Welcome
Content
This page is dedicated to the plants of the cactus family, Cactaceae.
With lots of pictures, locale information, authors, synonyms, and generic care tips. My goal is to build a unsable online cactus encyclopedia. Please apologize that this cactus encyclopedia cannot be complete because of the huge number of genera. I use the taxonomy of Curt Backeberg based on the book "Kakteen von A bis Z" by Walther Haage (1981).
Thanks to
My thanks goes to the famous cactus nursery Kakteen-Haage in Erfurt, which allowed me to use plant descriptions from the book "Kakteen von A bis Z" by Walther Haage and images from their plants inventory on this homepage. Furthermore, I would like to thank the Botanical Garden of the University of Heidelberg, which that allowed the use of pictures from the collection of cacti by Werner Rauh. Thanks to all the cactus friends who helped me with their words and pictures. My special thanks to Immanuel Voigt and Edward Bartlett for correcting the English translation. |

Care in May
General
Cacti exchange or buy, control newly acquired plants to pests scrupulously, take advice from literature for plant diseases and protection.
Light/Ventilation
Less sensitive cacti, e.g. Echinopsis, Cereus peruvianus, Trichocereus pachanoi or Opuntia bergeriana, Opuntia robusta, can now get a sheltered location outdoors or on the balcony. Keep it in direct sun also the plants behind glass only shade at midday.
Frequent ventilation is necessary.
Temperature
Many species of cacti need now a very hot location, e.g. Astrophytum, Echinocereus species. Do not allow that the temperature rises above 35°C (95°F).
Countermeasures: air, spraying or shading (best combined).
Water/Nutrients
Watering further increased, spray also on hot days. Clay pots are best imbeded in gravel or peat.
Best time for repot, best use subdued substrate, fertilize non repotted plants.
Reproduction
Good time for sowing and growing of cuttings.
Pest control
Check constantly the plant inventory (with a magnifying glass!). Isolate infested cacti from the collection and handle them separately, combined use of pesticides is advantageous. |
