PHOTOINFORMATOR of the Sumy cacti club (Ukraine), 1981
Editiors: Mrinskiy Vladimir, Burenkov Arlen
In this section we are going to publish materials on keeping plants, not only cutlivars. The main parts are composing soil mixtures, methods of softening water, greenhouses, fertilizing, winter conditions and so on. These are the questions frequently asked by beginners. I suggest taking questions and answers from the Russian-language posting www.egroups.com/group/cacti_in_russian.
Taking into consideration the climate of Russia we do not believe that these advice are acceptable for any other countries. That is why the materials will be published only in Russian.
