Hi Jess, welcome to our forum... Aloe Vera is a little more difficult to propagate from cuttings than most
succulents due to the quantity of moisture (gel) in the leaves, but it is possible and not
that tough. Beginners should start by rooting a complete leaf rather than a cut portion. Carefully pull (downward) a healthy lower leaf and remove it from the stem. Allow the leaf to set in a warm, dry location for 3 days until a callous has formed over the area where it connected to the stem. Then set the base of the leaf about an inch into some moistened, sterile
growing medium (I prefer vermiculite but you can use potting soil or sand) Keep the medium slightly moist, and keep it in a warm place (75 degrees). Roots will generally begin to develop in about a month. In 2-3 months a tiny new
plant will begin to emerge from the base of the cutting.
An easier method is to wait until the
plant matures and begins to create offsets, which can easily be removed from the mother. Normally these will already have a few of their own roots and be ready to place in their own pot immediately. If there are no roots, pot them up, but withhold watering for the first week.
Good luck!
