You don't need a greenhouse operation to experience the fun of growing Sagos from seed, all you need is a male and female in your yard. A cone has plenty of pollen and can be used on several females at a time, or on one several days in a row. Female begins to form a flower. Male cone is reaching maturity . Female flower opens.
Male cone is shaken over female to release pollen.
This should be done daily until the flower begins to close several days later. Female closes and begins to form seed during the summer months. Maturing seed will slowly turn from yellow to bright orange. Male cones will stay viable for a few days if kept in a cool place. Store in a plastic bag when you are not using them to pollinate females.
