Instructions for leaf propagation:

1. Prepare a propagation tray: Fill a shallow tray or pot with well-draining succulent soil or a mixture of perlite and potting soil.

2. Place leaves on soil: Lay the callused leaves flat on top of the soil, ensuring good contact between the leaf and the soil surface.

3. Mist lightly: Use a spray bottle to lightly mist the soil around the leaves. Be careful not to overwater, as succulent leaves are prone to rotting if they stay too wet.

4. Wait for roots to form: Place the propagation tray in a bright, indirect light location and wait for roots to form. This process can take anywhere from a few weeks to a couple of months.

5. Water sparingly: Once roots have formed, begin watering the new succulent plants sparingly, allowing the soil to dry out between waterings.

6. Transplant when mature: Once the new plants have developed a few sets of leaves and are established, carefully transplant them into individual pots filled with succulent soil.

7. Provide proper care: Place the newly potted succulents in a location with bright, indirect sunlight and continue to water sparingly, allowing the soil to dry out between waterings.
