Put a Christmas cactus leaf in a cup of water and it roots in a week; you can propagate several pots from cuttings

Christmas cactus enters dormancy in summer and basically barely grows! But after autumn arrives, the temperature difference gets bigger and the cool wind blows, and if you're not careful and don't know how to care for it, you'll kill it! So the safest method is to propagate it in advance. Do a good job of "copy and paste"!
It's not that hard to propagate Christmas cactus; just prepare a small cup of water and you're all set!
1. First, snap off a few healthy, bright green leaves, ideally ones with 2-3 segments, either by breaking them off directly or cutting them with sterilized scissors.
2. Let them dry slightly in a shady spot, then spray a little carbendazim on the cut ends to disinfect them.
3. Prepare a small cup with a narrow mouth and insert the leaf into it (narrow-mouthed bottles really aren't easy to find, so a mineral water bottle works as a substitute) (some gardeners also use a clever method: find a small cup, put stones at the bottom, and fix the leaf in place)
Let the bottom of the leaf touch the water surface, then place the bottle in a cool, well-ventilated spot. Change the water every 2-3 days.
4. Healthy leaves generally grow small white roots after 3-5 days in water, though there are exceptions. As long as the leaf doesn't rot or wilt, it can root.
After it roots, don't rush to plant it; keep it in water for another half month, and once the roots are stable, transfer it to soil.
5. Once the roots grow to about 2 cm, transfer it to a pot to plant, and after a week of acclimating to the pot, let it receive normal sunlight for care!
