Watering:
Allow the top of the soil (or half of it in low light) to dry out before watering. Can cope with some degree of drought.
Fertilizer:
Apply an occasional weak feed, if anything. Yucca does not need a lot of food.
Re-potting:
you should only repot a yucca when it is necessary. Typically, yucca will live in the same pot for about three years before needing repotting.
Temperature:
The Spineless Yucca is hardy and adapts well to pretty much any indoor room temperature. Do not allow the temperature to fall below 7°C at night.
