Yucca is a perennial plant in the agave family. Although yucca is a succulent, it is not part of the cactus family, according to master gardeners at Washington State University County Extension. Generally grown as an ornamental in warm region gardens, yuccas thrive in containers in areas with cooler climates.
Mix together moist peat moss and sand in a 3 to 1 ratio (3 parts of peat to 1 part of sand) and fill the new pot halfway with the mixture.
Remove the yucca from the old pot and gently loosen the outside layer of the root ball with your fingers.
Place the roots onto the soil in the new pot. Add or remove soil until the yucca is sitting at the same depth as it has been growing.
Fill the pot with soil and pack it around the base of the yucca with your hands.
Water the soil again, allow it to drain and place the yucca in a shady area. Allow it to remain for two weeks while it acclimates to the new pot.
