As mentioned,
Jade plant needs the most water during the times of year that it is actively growing. By contrast, in winter, when the plant is entirely dormant, you should reduce these already low watering needs. In fact, during winter, you should not water this plant at all. Once spring arrives, wait until your
Jade plants begin to develop new leaves. Once that occurs, you can return to your regular watering schedule. During the hottest parts of summer, your plant may enter another dormant growth phase, which means its water needs will be lower than normal. As summer ends and fall arrives, you can begin reducing your watering in anticipation of winter. By the time winter arrives, you should cease watering altogether.
