Propagate the sago palm by harvesting offsets, or pups, at the base or along the trunk's sides.
Remove them in early spring or late fall.
Gently dig with a spade while keeping the taproot in place on the baby sago palm. Lift them from the base or pop them from the trunk using a sharp knife.
Use a mix of 50% well-draining potting soil, 20% sphagnum moss, 10% perlite, 10% sand, and 10% compost.
Use containers with drain holes and four times the circumference of the plant.
Plant and keep the top 1/3 of the pup out of the soil. Fill the container with soil leaving about an inch from the top to prevent water spillage.
Water well. If the soil settles, add more soil around the pup, leaving about 1/3 of it exposed on top.
Wash off the leaves to remove any soil and debris.
Place in a bright indirect light area and water them consistently.
Note: These plants only grow about 1-2 inches per year. It might be several years before many fronds mature.
