I have a 2 year-old jacaranda mimosafolia bonsai and a regular sapling that I grew from the same batch of seeds. The bonsai is about 10" tall and the tree is abt 8' tall (it's very impressive to guests that these two trees are the same age). The sapling has flowered from the central trunk (blue flowers), and I'd like to know if the bonsai can be made to flower also. Is there something about the formation of the bonsai that inhibits flower production in this species? Should I try to apply a higher phosphorus fertilizer, or should I just forget it and enjoy the foliage?
