Culture: Abroma augusta need full sun to partial shade with a rich well-drained soil mix. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 2 parts sand or perlite. Plants are watered, then allowed to dry slightly before watering again. They are fertilized weekly during the growing season with a balanced fertilizer. They are very fast growing, so repotting should be done when they outgrow their containers. Care should be taken when repotting because of the irritating hairs. Wrapping newspaper around the trunk helps to prevent exposure to the hairs. During the winter months, water should be somewhat restricted, but not to a point where the plant loses its leaves.
