HAWAIIAN LAVA PLANTINGS OR POTTED LIVING SCULPTURE (OR KEIKI BONSAI)? Our lava plantings are ideal gift items for those wanting a very slow growing desk top decoration. They have a restricted established root system. Compared to a flower arrangement that may last just a week or two, these are nice gift items that will survive for a long period in an average home or office. But for optimum health and growth vigor to allow continuing development and training, give it optimum growing conditions with higher light and a larger root system by potting it. Fuku-Bonsai offers "conversion kits." As the roots grow into more media, it produces strong growth which can be pinched back to create additional growth points. The selection and development of the growth points is the key to training. Retain the ones where growth is desired and remove growth where not desired. If you want to train bonsai, Keiki Bonsai or Living Sculpture are recommended.
