Cacti need full sun exposure, with very few exceptions, and a long warm season exceeding 6 months to grow. The intense activity of the cacti takes place during the spring and summer period, during which, in addition to growth, they also give their unique flowering. As for winter, a period of dormancy, cacti seek temperatures of 5-15°C, although some of them can withstand sub-zero temperatures for a while. Cacti need coarse, sandy, draining soil to grow. An ordinary general-purpose potting soil is not suitable for cacti, as it retains a lot of moisture. That is why we use specialized potting soil for cacti enriched with nutrients. Cacti definitely need fertilization, especially during the spring and summer when they do most of their growth. Specialized fertilizers for cacti, water-soluble with enough trace elements, are needed to improve growth and give their wonderful flowering. We add water-soluble fertilizer to the cacti twice a month for the spring and summer periods.
Most people water cacti less than they should, affected by their resistance to lack of water. However, cacti definitely need watering once a week in the spring months and twice a week in the summer months. On the contrary, cacti need limited watering in autumn, while in winter it would be good not to get wet and not watered, especially in cold and frosty conditions. For the cacti we have indoors at home, we water twice a week in the summer months and once a week the rest of the time, including the winter.
