Kalanchoe cutting method one: choosing the season
Leaf cuttings of kalanchoe can be done throughout the year, but summer and autumn are best. Before cutting, prepare the cutting bed; the cutting medium is fine river sand or well-drained sandy loam.

When taking cuttings, first cut a length of stem from the mother plant, use a blade to cut off the leaves along the base of the petiole, rinse the cut surface with fresh tap water, then place it in a ventilated, shady spot. After the sap at the wound has dried, insert the cutting diagonally into the medium to a depth of 2-3 cm. After inserting, press the medium firm, then water, and spray the cuttings and the surrounding area once with a 50% wettable powder.

Kalanchoe cutting method two: requirements for different time periods
On the second day after cutting kalanchoe, spray the cuttings once with a mixture of 0.1% sucrose and urea. Because kalanchoe is a succulent plant with a high water content, it should not be watered too frequently at ordinary times; overly wet medium easily causes root rot, so water usually once every 2-3 days. In rainy weather, take care to prevent rain exposure. Roots will form in about half a month, and after 3-4 weeks the callus tissue at the base of the petiole can grow small adventitious buds. After the buds emerge from the soil, spray once with a mixture of 0-2% monopotassium phosphate and sucrose.

After that, spray a 0.5% foliar nutrient solution for flowers once every 10 days. After a month and a half, the plants can be potted up and transplanted. A well-drained, loose, fertile sandy loam is best for the potting soil. After potting, water once every 2-3 days. In winter, if the temperature is below 5°C, move the plants indoors to overwinter.
