During the active growth period, water the plant once per week, but ensure it has excellent drainage and dries out between waterings. If temperatures get too hot, it may need more frequent watering.
Fertilize your indoor yucca plant during the growing season with liquid fertilizer. Once-a-month feeding is usually sufficient.
Yuccas do well if they are slightly pot-bound, as long as they don’t become heavy enough to tip over their containers. You won’t need to bother with repotting for at least two or three years.
10 – 21 °C is the perfect temperature.
