How do you root a jade cutting?

Answer 1

You just stick it in moist soil.
"Some plants such as a jade plant can be started from a single leaf of the plant. To do this, find a healthy leaf and break it off. Place the leaf with the pointy side down in a pot of potting soil. Push the leaf into the dirt slightly. Water the leaf and put the pot in a sunny window.Place the pot in a plastic bag to keep in moisture. In about two weeks you will notice that the leaf has taken root and has begun to grow. Remove the plastic bag".

Answer 2

Either method is easy and usually quite successful if certain procedures are followed. When making your cuttings, be sure to use a sterile, very sharp knife! The surface of the cut should then be lightly dusted with a rooting hormone. ( The cutting should then be left in a warm, dry place until a callous developes over the cut. The cutting may then be planted into sterile potting soil, or set temporarily into a rooting medium such as vermiculite or perlite. Watering should be kept to the bare minimum (barely damp), and then gradually increased as the roots begin to develop. Ideally, the soil temperature should be kept at 75 degrees F. which will speed the rooting process considerably. Jade leaves can also be used to create a clone, but this method will take much longer before you have a specimen size plant. Leaves will take only a few days to callous, after which you simply insert the base of the leaf slightly into lightly moistened potting soil or rooting medium. It may take a month or longer for the cutting to root and the plantlet to start growing from the base of the leaf. Gradually increase the watering as the plant grows until it has reached a size suitable for repotting. With either method, feeding should be withheld until the new plant has become established, and even at that point should be a dilute half strength mixture of the fertilizer.
