TEMPERAURE: measurable from spring to fall. In winter it’s recommended to keep the temperature about 16C, but it’s possible to keep it in lower temperature, even in 5C. Plants, standing on a window-sill in a not-heated place, should be put inside in cold nights.
LIGHTNING: it needs a bright light.
WATERING: In spring and summer – measurable, better with warm water. From summer end watering is reduced and shortly limited by midfall – watering is rare and short.
ATMOSPHERIC DAMP: it doesn’t need spraying in summer.
REPLANTING:each year in a young age, further in spring by perforce. A new pot should be a bit bigger than a previous one.
BREEDING: the stems of many species are easily rooted in spring and summer. The stems are dried up during some days. Seed breeding is possible.
