Plant the seedlings outdoors in full sun in an area large enough to accommodate a tree of the Canary Island date palm's stature. Ensure that the soil drains well.

Remove fronds that are hanging below horizontal, by hand using an offset lopper, as the tree grows. Be sure to wear leather gloves, as the fronds have sharp edges.
