Watering is the most difficult part of keeping aloe vera healthy. Aloe is a succulent plant accustomed to arid environments, but it's thick leaves still need enough water.
1. Water your aloe vera plants deeply, but not very often.
2. The soil should feel damp after watering, but allow it to dry slightly before re-watering. If the soil is left too wet, the roots of the plant can rot.
3. To prevent over-watering your plant, allow the top third of your potting soil to dry out between waterings.
4. Plan to water your aloe plant about every 2-3 weeks in the spring and summer, and even less frequently in the autumn and winter. One rule of thumb for fall and winter watering is about twice the time between waterings (compared to your summer watering schedule). In other words, if you water every two weeks in the summer, water every four weeks in the winter.
5. When watering, excess water may drain to the bottom of the pot. Let the pot be in this water to allow the soil to absorb it as much as possible. Wait 10-15 minutes, then drain off the remaining water.
