Cut the leaf from the plant with a sharp, clean knife. Cut of the bottom third of the leaf from those with petioles or cut off a 2- to 4-inch length from the tip of of a leaf from those with bladelike growth.
Dry the cutting in a well-ventilated area, away from direct sunlight, for one to two days. Drying allows the cut to develop a callous that prevents fungal growth after planting.
Fill a 4- to 6-inch diameter flower pot with moistened sand or vermiculite. Use a pot with drainage outlets in the bottom.
Push the cut end of the leaf into the sand until it stands upright on its own. Cover the top of the pot with a clear plastic bag, arranging it so it doesn't touch the leaf.
Place the pot in a warm, brightly lit area that isn't in direct sunlight. Water the sand when it begins to dry out. The cutting is rooted once it begins producing new growth, usually within four to six weeks for most succulent varieties.
