Additional Landscape Use Information

ʻIhi becomes very leggy and succumb to a number pests, especially slugs and snails and fungal rot if given too much water. These are great potted plants for the often harsh conditions on full sun and windy porches or lānais. If kept in containers, use cement, terra cotta, or unglazed ceramic pots which are preferred over plastic ones. These types of potting containers tend to breath better and allow potting mix to dry out quicker, essential for the health of these xeric plants. Too, the weight of the pots will help these succulents from toppling over in windy conditions and as they grow larger in the pots. [David Eickhoff, Native Plants Hawaiʻi]
