Growing akulikuli takes patience. At one time I had huge beds of akulikuli and people walking by would ask for cuttings. Many of them asked me your question. Simply surround your plants with compost and they'll eventually spread out and take root. I recently opened a new bed and only half of the cuttings survived. I know they'll one day be a thick bed of purple blooms. Yours will too!

Mahalo nui for the advice! I will definitely try the compost.
