Generally, sago palm blooms once every three to four years from the month ranging from April to June with either male or female flowers, which are called cones. The plant takes 15 to 20 years to reach maturity and bear flowers.

Pollination of the Sago Palm Flower

When the sago plants are sexually matured, the female sagos begin to flower bearing a basketball-sized structure while the male sago produces a long thick structure or the male cone.

At this point, you have the opportunity to propagate and get new sago plants elsewhere in your yard or share them with your friends.

The natural pollination process in Sago Palms is not complex however, hand pollination requires more effort.

1. Natural Pollination

Wind and Insects, especially sap beetles are two natural agents for the sago palm flower, which help in the pollination process.

Wind pollination is only viable if female and male plants are 2 meters apart so, keep your palm couples near to ensure a successful pollination process.

During the months of pollination, male and female plants release a strong odor containing a chemical compound, Estragole, that attracts the insects to assist in the pollinating act.

Moreover, insect pollination is helpful in rainy seasons, when pollen availability in the air becomes low due to the rain.

2. Hand Pollination

Hand pollination can helpful when male and female plants are far from each other and you can successfully perform this from April to June.

Cut the male cone and rub it over a female flower when the flower opens. 

Follow the steps below to complete the successful hand pollination of sago palm.

  • Wait for the time when your male flower produces pollen and the female flower opens.
  • Wear gloves and a mask at all times during the process.
  • After pollens appear in the male flower, cut the entire flower from the base using a saw.
  • Take the male flower to a nearby female flower and rub the cone or tap it with your hands to sprinkle the pollen over the female flower.

If you have two male flowers, rub them together over the female flower to sprinkle the pollens.
