When to Water Sago Palms
How much water do sago palms need? During the growing season, they need moderate watering. If the weather is dry, the plants should be watered deeply every one to two weeks. Sago palm watering should be done thoroughly. About 12 inches (31 cm.) away from the trunk, build up a 2 to 4 inch (5-10 cm.) high berm (a mound of dirt) in a circle surrounding the plant. This will trap water above the root ball, allowing it to drain straight down. Fill the space inside the berm with water and allow it to drain down. Repeat the process until the top 10 inches (31 cm.) of soil are moist. Don’t water in between these deep waterings–allow the soil to dry out before doing it again. Water requirements for sago palm trees that have just been transplanted are a little different. In order to get a sago palm established, keep its root ball consistently moist for the first four to six months of growth, then slow down and allow the soil to dry out between waterings.
Watering a Potted Sago Palm
Not everyone can grow a sago outside in the landscape so sago palm watering for those that are container grown is often performed. Potted plants dry out more quickly than plants in the garden. Watering a potted sago palm is no different.
If your potted plant is outdoors, water it more frequently, but still allow the soil to dry out in between. If you bring your container indoors for the winter, you should slow down watering considerably. Once every two to three weeks ought to be enough.
