Cereus peruvianus is a very fast grower. This cactus is a perfect candidate indoor plant for a sunny windowsill.
Light: Grow Cereus peruvianus cacti in the fullest possible sunlight. Since the light coming from a window is one-sided, a columnar plant will tend to lean in that direction and so it is most important to turn such plant frequently.
Temperatures: Normally warm temperatures are usually suitable in spring, summer and autumn. For the winter these plants should be moved into a cool position – around 10°C if possible – where they can rest. A Cereus peruvianus that tries to continue growing in poor light of the short-day months will develop an abnormally thin, frail stem.
Watering: During the active growth period water moderately, but allow the top centimetre or so of the mixture to dry out before watering again. During the winter rest period give Cereus peruvianus just enough water to prevent the mixture from drying out.
