Pour 5 pounds of sand into a large bucket, then add in 5 pounds of peat moss and 5 pounds of perlite. Stir the mixture well with your hands to ensure that all the materials are combined completely.
Fill a 28-inch terra-cotta pot three-fourths full with the perlite mixture, and dig a 4-inch hole into the center, using a spade.
Take the jade plant out of its container, holding the base of the jade plant in your left hand, with the soil plug facing up.
Place the soil plug into the hole you created in the perlite mixture, then fill the rest of the pot with the remaining perlite mixture.
Water the soil thoroughly and place the repotted jade plant in a sunny location.
