Pre-treatment: Work in a shady area. Use clean 3" pots arranged in a tray with well-drained potting mix. Cut plants into desired lengths, at least 3 nodes per strand. No rooting hormone is needed. Fill the rest of the pot with potting mix. Water daily and keep cuttings in a moist humid environment by misting several times during the day.

Establishment: The plant is indigenous to Hawai'i and grows well in coastal habitats, rocky shores, sea cliffs, and salt marshes. It is highly salt-tolerant and can dominate saline habitats where few other species can survive.
