A jade plant, known scientifically as Crassula argentea, is a succulent plant, which means that it takes up and holds a lot of water. Jade is commonly planted as a houseplant, and in ideal conditions it can grow to a height of up to 10 feet tall. Jades can be fussy plants, and one of their main problem points is watering. Too much water can cause root rot and too little water can cause the plant to dry up. Knowing how and when to water your jade plant will keep it healthy for years.
Feel your jade plant's soil. If it is moist, allow it to dry out.
Water the jade plant thoroughly until water begins to run out into the bottom tray. Once you see the water begin to come out, stop watering. Water your plant by pouring the water onto the soil on the side of the container, not from directly overhead.
Wait 30 minutes then empty any standing water that has run out from the pot.
Allow the jade plant soil to completely dry before watering it again.
Water the jade plant only once a month during cooler winter months, as the plant is in a dormant phase.
