Jade plants are gems among houseplants, favored for their distinctive appearance and glossy, plump leaves. Jade plants are easy to grow as long as you give them a little water and plenty of bright sunlight. They can grow to be very large, and often live so long that they're handed down from generation to generation. If you have a healthy jade plant, you can propagate more plants with just one leaf.
Remove a healthy leaf from the jade plant with a sharp, sterile knife. Cut it just below the node, which is where the leaf connects to the stem.
Mix a growing medium of half vermiculite and half commercial potting soil. Fill a planting container with the mixture. Any planting container will work, as long as it has good drainage in the bottom. Mist the soil very lightly until it's just barely damp. If jade leaves are exposed to too much moisture, they will rot.
Dip the cut end of the jade leaf in rooting hormone and lay the leaf on the top of the soil. Don't add more water until the leaf takes root, which will take between two weeks and two months. Keep the pot in a warm room, between 70 and 75 degrees F.
Gradually increase the water very slightly after the leaf roots. Once the new jade plant is 2 inches tall, you can water it like an adult jade plant. Let the soil dry out completely between each watering, and then water it deeply.
