Tree Management

Propagated by seed planted directly but sometimes wild seedlings are collected and transplanted. Young trees require shade and wind-breaks may be needed in exposed sites to prevent breakage of leaves. Plant at 6-7 m or about 250 trees/ha. Tree reaches full size in 6-15 years. Fibers can be collected after 5-6 years then every 2 years. Can tap when flowering begins but usually only done from male inflorescence stalks. One inflorescence produces ~5 liters sap/day and can be tapped for 1-2 months with 2-4 inflorescences tapped at a time. Sap production maximized with tall inflorescence. Sago requires cutting the trunk and therefore is the last product obtained. Generally only trees ≥30 years are cut. Best planted on steeper slopes, easily eroding lands, or in single or double rows near farm boundaries due to its heavy shade and extensive root system. Good soil stabilizer.
