Harvest Tips
Loʻulu is grown as an ornamental tree rather than harvested for fruit. Traditionally, mature fronds were cut sustainably for weaving (harvest only mature fronds, leaving the growing heart intact). Leaves are best harvested after they have fully matured and hardened. Seeds can be collected from ripe fruits in late summer/early fall and cleaned for propagation.
