Aloes are part of a group of plants known as succulents, which store water in their swollen leaves. Aloe plants are grown for ornamental purposes, but the aloe vera variety (Aloe barbadensis) is also grown for its leaf juice which is used for medicinal purposes, such as for moisturizing the skin. As your aloe plant becomes larger and self propagates, it will likely outgrow its space and need a larger pot to grow well. Replant your aloe plant anytime and repeat as necessary, usually every six to 24 months.
Remove the aloe from its current pot. Tap the sides or press them in if they're pliable to help in this step and turn the plant over. Gently hold onto the plant near the base if necessary. You can also use a knife to go along the edges between the soil and the pot to help loosen it.
Lay the aloe on a piece of newspaper and gently begin to look through the soil and the roots. Separate with your hands any aloe offshoots and their roots from the main plant. This step is optional, but offshoots use up valuable energy and can cause the aloe to develop flat leaves. Offsets can be repotted as well, if desired.
Fill another larger pot three-fourths to two-thirds of the way to the top with new, well-draining potting soil. Potting soil labeled for cacti will suffice. Use a pot with drainage holes, or layer about 1 to 2 inches of gravel on the bottom before adding the soil.
Plant your aloe plant to the same depth as it was planted before. Dig a hole with your hands that is large enough to accommodate the roots.
Water it slowly until it seeps through the drainage holes. Dump out any extra water and set your aloe plant in full sun. Do not water again until the soil dries out.
