Jade plants ("Crassula argentea") are tropical succulents that are native to South Africa. Because of their sensitivity to cold, jade plants are commonly grown indoors as houseplants in most climatic regions. The jade plant is low-maintenance and has fleshy, thick stems with thick green leaves that are 1 to 2 inches long and have reddish edges. Jade plants can grow up to 10 feet tall outdoors but usually remain much smaller when grown indoors. In winter, the jade plant blooms with numerous, small, star-shaped white flowers borne at the branch tips.
Place your jade plant in bright, direct sunlight. If you're moving the plant from a lower-light location to full sun, set it in the direct light for a few hours each day to gradually acclimate it to the new location. This will prevent sunburn of the leaves.
Keep air temperatures around your jade plant above 45 degrees Fahrenheit at night and below 100 degrees during the day. Jade plants prefer low air humidity.
Water your jade plant thoroughly once each week until the water drains freely from the bottom of the pot. Water when the top inch of soil feels dry to the touch; discard excess water from the drainage dish after watering.
Feed your jade plant a balanced liquid houseplant fertilizer containing trace elements or "micronutrients" from April until October. Feed the jade plant once or twice a month at half the recommended dosage strength.
Drench the potting soil once every one or two months to leach out any fertilizer residues that have built up in the soil. Water the jade plant until the water drains from the bottom of the pot for two or three minutes.
Induce flowering of your jade plant by reducing watering frequency to once per month and withholding fertilizer from November through March. During this time, keep your jade plant in a spot that has total darkness with no exposure to artificial lights at night.
