You can totally propagate succulents in the winter

There are two different types of cuttings that can be propagated to grow new plants: stem cuttings and leaf cuttings. To take a stem cutting, use a pair of sterilized scissors to cut off a piece of your succulent just above a leaf on the stem. For a leaf cutting, gently take hold of the leaf you’d like to use. Espoma recommends a larger, mature leaf that looks healthy with no blemishes. Wiggle it back and forth until it breaks off from the stem. Make sure the leaf breaks cleanly all the way down to the stem, without leaving any pieces of the base behind. To propagate successfully, the new “baby plant” needs a fully intact leaf.

If you’d like your cutting to root more quickly, dip the end in rooting hormone. Succulents will root quite easily on their own, making this step not as critical as it is with other species of plants.

Before planting the cutting into soil or perlite, it’s important to allow the cutting time to form a callus.Nothing special needs to be done to facilitate this part of the process. Simply lay the leaf or stem cuttings in a bowl, or right on the windowsill to dry down. The end should form a callus within a few days.
