Jade plant, Latin name Crassula argentea, is a perennial succulent native to South Africa and prized as a tough, easy-to-grow houseplant in the United States. The plant thrives in warm household conditions and can only tolerate an outdoor growing environment in USDA hardiness zones 10 through 11. The slow-growing plant will eventually reach heights of up to 5 feet indoors and, when provided with proper care, jade plant lives for decades. It produces small, white flowers in spring, although it may take several years to begin blooming, and thick, evergreen foliage all year.
Keep jade plant in a south-facing window to provide bright, filtered light throughout the day. Use a thermometer to maintain a daily temperature of 65 to 75 degrees Fahrenheit and a nightly temperature of 50 to 55 degrees Fahrenheit.
Water once per week during spring and summer months to provide ample moisture while the plant is actively growing. Decrease the frequency of watering to once every 10 days during fall and winter, when the plant is dormant.
Feed jade plant once every three months using an all-purpose liquid houseplant fertilizer. Follow the manufacturer's directions for proper application and dosage. Do not fertilize during winter months, as the nutrients are unnecessary during dormancy.
Remove fading jade plant flowers as soon as possible to prolong blooming and prevent the formation of seed heads. Pinch off the flowers where they emerge from the stem to prevent damaging the plant.
Repot once every five years to allow room for the root system to expand. Increase the size of the pot by about 5 inches at each repotting. Use a growing medium made of one part organic soil, one part sphagnum moss and three parts coarse sand.
