Propagate kalanchoe this way: roots in about a week, a potted plant in a month

Kalanchoe (Kalanchoe blossfeldiana) easily grows aerial roots in humid air. If you want to use stem cuttings for propagation, it is best to choose stems that already have aerial roots, or pick thicker, sturdier stems. Choosing such stems gives you, first, ample stored nutrients, and second, they root more easily or already have fine roots themselves, so the cuttings take hold more readily.

When propagating from leaves, keeping some of the leaf stalk (petiole) attached helps them root faster. Choose thicker, fleshier leaves, as they hold more nutrients. Insert the petiole into slightly moist soil, but do not push it in too deep, or it will affect the leaf's ability to send out shoots. Just keep it in a warm, ventilated spot for care.

On the mother plant after the stem is cut, you can see new shoots emerging from both sides of the stem, so gardeners should remember: if you cut stems yourself, cut about 1 cm above the axillary bud, as this helps the mother plant branch. Buy a rooting container, or make your own rooting device using foam that just covers the container. Cut small holes in the foam just big enough to hold the kalanchoe stem. Finally, fill the container with just enough water to touch the roots, place the foam in the container, and insert the kalanchoe stem into the foam.

The water placed there will basically evaporate and be absorbed within a day, so we must top up the water promptly to let the stem absorb enough moisture. If we do not do this in time, the whole stem will wilt from lack of water, or even die. After doing this, in a week many fine roots will grow. Excessive direct sun: although kalanchoe likes light, if it gets too much sun, the leaves will soften and the leaf edges will turn dry and yellow.

Propagating in sand: on one hand, water drainage is relatively good; on the other hand, water evaporates relatively quickly, so the moisture level for rooting is guaranteed! Cut a more mature kalanchoe stem, about 6 cm long, insert it into the sand, cover it with a plastic bag, and keep the temperature at around 20°C; it will root in about 15 days. In a month it can be turned into a potted plant! Note that the plastic bag needs to be opened every day for ventilation, or punch a few more small holes around the plastic bag, so the kalanchoe does not suffocate to death!

It likes sunlight and tolerates partial shade; it fears severe heat in summer and cold in winter. Kalanchoe likes a sunny, well-lit environment, and can also grow indoors in partial shade. The most suitable temperature for kalanchoe growth is 15-25°C; in summer it needs shade and cooling, and in winter it needs to be kept warm.
