Repot aloe vera plants in early spring to provide room for new growth. An ideal container has drainage holes and is 1 to 2 inches wider than the current container; aloe vera prefers well-drained soil, and soil dries too slowly for this succulent when it's in an excessively large pot. If your aloe plant produced "pups," or offshoots, from the base, detach them from the parent plant during the repotting process, if desired, to establish them as independent plants in separate containers.
Turn the plant container on its side. Grasp the base of the plant and gently pull and twist it to remove it from the container.
Remove the bulk of the soil from the plant's root system by crumbling it away with your fingers.
Cut pups away from the parent plant with a knife if you wish to replant them separately. Set them aside.
Cover the drainage hole of the new container with several pieces of gravel or a shard of broken pottery. This stops soil from falling through the hole but allows water drainage.
Fill the bottom of the pot with fresh potting soil. Use prepackaged potting soil intended for cacti and succulents, or mix equal parts of sand, leaf mold and garden loam in place of potting soil.
Set the aloe plant in the pot and fill the surrounding gaps with potting soil up until it covers the crown of the root system.
Press the soil lightly with your fingertips to compress it, then wait approximately one week before watering it.
Allow separated pups to sit for two days before planting, as recommended by Illinois University's Extension Center. Open wounds on the pups from knife cuts will form calluses during this time.
Repeat Steps 3 through 6 when planting the aloe pups. A suitable container size is one which is approximately 1 to 2 inches wider than the pup.
