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 January
General
Complete plant register or files.
Light/Ventilation
Offer as much light as possible. Winter rest of cacti is also at less bright or
even obscure locations possible
(e.g., stairways, corridors, basements).
Remedy with additional light if possible.
Provide light shade for plants wich stand
immediately behind glass (e.g. behind the window)
in strong sunlight. Give cacti on
mild days fresh air (hardening,
no premature growth). Avoid cold air or drafts.
Temperature
Winter rest of cacti is usually between 8 to 12°C (46 to 53°F), control with a minimum-maximum thermometer is advantageously. Some cacti groups need higher temperatures: 10 to 15°C (50 to 59°F), e.g. Hylocereus, Myrtillocactus, Pachycereus, 18 to 20°C (64 to 68°F), e.g. Rhipsalis, Schlumbergera, Selenicereus. Other groups are to be kept cold at 5°C (41°F), e.g. Echinocereus, Rebutia, Lobivia, Aylostera, Chamaecereus.
Protect the plants in addition in severe frost (cardboard templates on windows, heating coils, or fan in unheated spaces, cover plants with bubble wrap in the greenhouse.)
Water/Nutrients
None or only a little watering, sunken pots: moist only the surrounding material.
Schlumbergera and Rhipsalis need regular watering.
Provide Christmas cactus a few weeks rest after bloom, then repot.
Reproduction
Sowings with additional light and heat are possible, this requires thorough disinfection of soil and seed receptacles.
Pest control
Fight against snails and woodlice if wintering in the basement and greenhouse. |
