1. Keel can be cut from small branches. Let the cuttings dry for a period of time (1-2 days) before inserting them. It is best to insert them into plain sand. The moisture in the sand should not be too high. High humidity will cause roots to grow. If it is slow or even rotting, you can spray it with a sprayer and it will start to take root in about a month.

2. Place the keel in a ventilated and cool place for about a week to dry the wound. Place the incision downward on the surface of the potting soil. Do not bury it in the soil. The potting soil should be dry and do not water. Don't worry about the keel drying out, it will decompose water from the fleshy stem to encourage rooting. Do not water before taking root, otherwise it [will] rot easily.

3. After about ten days, white roots will grow from the incision. When the roots grow to three or four centimeters long, they can be replanted and watered. Daily management is extensive, and it needs to be watered as little as possible to tolerate exposure and barrenness. Use less fertilizer. The keel is suitable for lazy people to raise, because if the owner is too diligent, it will die quickly.

During the winter dormancy period, you can water it once every 1-2 months and it won't dry out. Keel flowers are not cold-tolerant, and the overwintering temperature should be controlled at about 10 degrees. In order to prevent the keel flower from rotting in winter, it needs to be placed in a sunny place to let it get more sunlight, and repotted at certain intervals. Keel flower has no strict soil requirements and can grow well in ordinary culture soil.

3. Although keel flowers are sun-resistant, keel flowers are not mainly used for viewing flowers, so appropriate shade should be provided in summer to facilitate growth. Keel flowers placed indoors should be placed as close to a window as possible to allow them to see more sunlight. In order to make them grow well, apply light fertilizer every 15-20 days during the growth period. The fertilizer should be granular compound fertilizer or homemade Alum, fertilizer and water can be used. However, the fertilizer should not be too thick to avoid fertilizer damage and root rot.
