Place a small piece of window screen at the bottom of the planting pot. The screen will prevent soil from draining out and the cactus roots from growing out of the pot.
Place a small amount of sand at the bottom of the pot. Course sand is excellent for drainage and ensures that no root rot occurs.
Fold the newspaper into a 3-inch wide strip and wrap it around the yucca plant to prevent the spines from poking. Jiggle the yucca slightly at the grafting site to verify that it is firmly healed and completely bonded.
Gently loosen the cactus from its pot by pinching the sides if the pot is plastic or gently rolling it along its sides if the pot is clay.
Remove the cactus from its pot and place it in the center of the new pot. Fill the remaining space with sand.
Moisten the soil and place the cactus in a sunny space.
