How to Grow Sago Palm

Despite the common name, sago palm (Cycas revoluta) technically isn't a true palm tree at all. These fairly low-growing plants with long green fronds are actually cycads, a group of ancient tropical and subtropical plants that usually grow from a trunk that doesn't branch out; it produces nuts but doesn't flower or fruit.

Sago palms are native to warm parts of Japan and southern China, and in cooler climates, they're often grown as houseplants. When grown in the garden, they're best planted in the early spring or late fall. These plants are extremely slow-growing and often put out only one new frond each year, with the feather-like foliage growing in a symmetrical ring. They generally grow larger when planted in the ground versus when they're in containers. After several years, they may reach 2 to 3 feet, but reaching a maximum of 10 feet can take as long as 50 years.

Sago Palm Care

Sago palms are not difficult to grow and maintain, but they do require some specific growing conditions. They appreciate a warm and bright environment, though harsh sunlight can damage the foliage. They also like humidity, which can be created by misting them regularly with clean water from a spray bottle. You also can place the plant container on a tray filled with water and pebbles, as long as the bottom of the pot isn’t touching the water (which can cause root rot). 

These plants are sensitive to overwatering and poorly drained soil. So make sure the soil surface dries out in between waterings. And choose a pot with ample drainage holes for container plantings. Many gardeners prefer to use unglazed terra cotta pots because any excess soil moisture can evaporate through the material.


Sago palms prefer bright, indirect light. Avoid placing them in direct sunlight, especially hot afternoon sun in the summertime, which can wilt and burn the foliage. However, too much shade can result in sparse foliage and an overall unhealthy plant. When grown indoors, choose a bright east-, west-, or south-facing window. Indoor plants can be moved outside in warm weather, as long as the container is placed in dappled sunlight.


Sago palms aren't overly picky about their soil, as long as it has good drainage. A sandy soil that's somewhat rich in organic matter and has a slightly acidic to neutral soil pH is ideal. For container plants, a potting mix made for palms should be suitable.


Sago palms have some drought tolerance, but they prefer a moderate amount of moisture in the soil. Water whenever the soil feels dry to the touch, making sure never to overwater to the point of soggy soil. Slightly reduce watering in the winter when the plant is not actively growing.

Temperature and Humidity

These plants love warm, humid conditions. They can briefly tolerate cold temperatures, but frost can damage the foliage, and temperatures below 20 degrees Fahrenheit will likely kill the plant. When grown indoors, protect your sago palm from drafts and airflow from heating and air-conditioning vents, which can cause extreme temperature fluctuations that can damage the plant.


For optimal plant health, fertilize monthly throughout the growing season (spring to fall) with a liquid fertilizer. Or use a slow-release fertilizer two to three times during the growing season, following package instructions.

Other Sago Palm Species

There are other plants that use the common name of sago palm, though Cycas revoluta is the one that’s most widely cultivated. The other species include: 

  • Cycas rumphii (queen sago): This plant grows more like a tree than a shrub, reaching around 15 feet tall.
  • Cycas circinalis (queen sago palm): This plant also is tree-like, reaching around 10 feet tall, and is native to India.
  • Metroxylon sagu (true sago palm): Unlike Cycas revoluta, this plant is a true palm that’s part of the botanical family that contains other popular palm trees.

Propagating Sago Palm

Palm propagation is typically done by seeds. But this process can be time-consuming and is often ineffective, so many home gardeners choose not to attempt it.

You can more easily propagate sago palms by division. When grown under ideal conditions, sago palms may send up clusters of new plants around their base. These baby plants can be removed from the parent plant by cutting them at the trunk with a sharp knife or scissors, leaving as many roots attached as possible. Then, place them in the shade for a few days to let the cut heal over before potting them in the same type of soil used for the parent plant.

Potting and Repotting Sago Palm

Because they grow so slowly, sago palms need repotting only every three years or so. However, it's a good idea to gently remove the plant from its pot every spring and replace the loose soil with fresh soil to ensure continued healthy growth. This plant grows best in a soil-based potting mix amended with sand and peat moss. 

Common Pests/Diseases

Sago palms don't have serious issues with pests or diseases. But scale and spider mites can become problematic. Look out for foliage damage or discoloration, as well as tiny bugs among the fronds. Aim to use a natural insecticide before turning to harsher chemicals, and make sure your plant has enough humidity and airflow.
