Aloe vera plants are good houseplants because they require little in the way of care. However, you may need to re-pot your aloe vera plant if it appears to be outgrowing its current container. The most important thing to keep in mind when transplanting aloe vera is that the plant grows out more than it grows down because it has a shallow root system. The new pot should be wider than the previous one to allow the aloe vera to stretch out, but the depth doesn't matter as much.
Make a mixture of half potting soil and half sand and fill the new pot about halfway with the mixture. Aloe vera requires a loose, sandier soil that encourages drainage because too much moisture can rot the plant's roots.
Loosen the aloe vera plant from its old pot by sliding the spade around the inside of the pot where the soil meets the container. Slide your fingers underneath the base of the plant (where it meets the soil) and tug up gently until the plant and its root ball are released from the pot.
Center the plant in the new pot and fill in the rest of the space with the potting soil mix. Set the pot in a clay saucer to catch runoff water.
Water the plant until the soil is damp. Place the plant in a sunny, warm spot.
