Now we wait. Before we can place our leaves on soil to begin growing new plants we must let the ends dry out and callous over. This step is vital! If you don’t let the ends dry out and place them directly on soil they will absorb too much moisture and they will rot and die. In addition to letting the leaves callous over, we must also let the end of the stem on the rosette dry out as well. This could take anywhere from a few days to a week or so.
Once you feel like the ends are dry enough, you can place them on top of some well-draining cactus or succulent soil. (Some people dip the ends in a rooting hormone, but I’ve never tried this and have had great success without it.) I’ve had the best results when keeping my leaves indoors in a window with lots of indirect sunlight.
After a few weeks you will see little pink roots sprouting from the ends of the leaves and then teeny tiny baby plants will begin to grow. I water the leaves very rarely until I start to see roots or babies appearing.
At this point I will give the roots or baby plants a good soak about once a week or whenever I notice the soil is totally dry. Just like with a fully developed succulent, too much water is not good. If you want to be certain not to over water, I recommend spraying the ends of your leaves with a spray bottle once a day instead of completely soaking the soil.
