Native to the Arabian Peninsula, this succulent comes from dry, open ground where rain drains quickly and roots sit in airy, mineral-rich soil rather than dense, moisture-holding earth. That natural setting explains why Aloe vera prefers a sandy, loamy, or slightly rocky substrate.
The best soil for Aloe vera is loose and sharply well-drained, with enough structure to anchor roots but not enough fine material to stay wet for long. Its roots are relatively shallow and adapted to brief moisture followed by drying, so good aeration is just as important as drainage.
