Best practices for survivability and field observations

Respondents noted that it is a hardy, small shade tree, and that it can become aggressive, spreading easily and that it grows in dry and also rocky areas. One mentioned that it can be slow growing to start and low in habit. Several noted that it can handle hot, dry conditions (for example Ahihi Kina‘u, Maui), and that it appears to recover after fire. One noted it can be messy in urban settings and that the fruit is a slipping hazard. Reviews were mixed on the fruit, noting it can be messy and a slipping hazard and its scent–one saying it smells bad, while another said the extent of the odor is exaggerated. Reviews were mixed on establishing noni at 2000′. One reported “some plants thrive while others barely survive or die quickly” while two respondents said that when it is planted closed to māmaki, this works well. Cultural uses include kapa dyes, for medicinal uses.

Stressors and pests

One respondent said that there are diseases that will attack it, and another said that deer will browse it (as a last resort).

Availability and propagation

Many said that it is fast growing, readily available by seed (sources include Kauluwehi, UH/MC campus), cuttings and root suckers.
