Jade plant, or Crassula arborescens, is a popular houseplant easily grown and cared for by beginners. One problem that new gardeners often run into with the jade plant is overwatering. Nothing will do in a jade plant faster than too much water or letting it sit in water. However, with conservative watering and good natural lighting, it can last for years and provide indoor color during the winter. Like the Christmas cactus, jade plants normally bloom around the holidays provided they are allowed to grow under natural lighting conditions. Since they take their cue from the shortening days, a jade plant grown in rooms with lots of artificial light at night will usually fail to set buds. If the plant does not receive enough bright natural light, it will start stretching out and become leggy.
Jade plants have distinct growing and dormant cycles and require different treatment during them. Water regularly in spring and summer, allowing the jade plant to almost dry out between watering. Water liberally, but empty any extra water from the saucer after you're done. In the winter, when the plant enters dormancy, stop watering it. The leaves will lose some of their thickness, a sign that this succulent is using some of its stored water. If the plant starts to lose its leaves or develops spots on the leaves, it probably needs water.
Daytime temperatures of 65 to 75 degrees Fahrenheit and night-time temperatures of 50 to 55 degrees Fahrenheit provide an optimal growing environment for your jade plant. They can tolerate higher temperatures if they're getting plenty of full sunlight. Fertilize your jade plant twice a year with water soluble liquid fertilizer. Always fertilize after watering as fertilizing a dry jade plant will damage the roots.
