Growing jacaranda trees is mostly a matter of having the right environment, as they’re strictly southern trees that thrive in Florida and parts of Texas and California. Gardeners living further north often have success growing jacaranda as a large houseplant and they have been known to make spectacular bonsai specimens.
Jacaranda Tree Information
Jacarandas are true southern trees, thriving in USDA plant hardiness zones 9b through 11. Jacaranda tree hardiness is tested when the temperature drops below 15 degrees F. (-9 C.), and they do best above the freezing point. They prefer a sandy soil with great drainage, and show off their lavender blooms best when planted in full sun. They grow relatively fast and will get up to 60 feet tall (18 m.) and just as wide. The spreading branches may fill your entire front yard.
How to Plant and Care for a Jacaranda Tree
Choose the spot for your tree wisely. One piece of jacaranda tree information that many nurseries and catalogs don’t share is that when the flowers drop, they cover the ground in a thick layer and must be raked up before they decompose into slime. An afternoon with a rake will do the trick, but this is the reason so many jacarandas are planted as street trees, allowing most of the spent blooms to fall on the street instead of in the yard. Plant the tree in an open spot with sandy soil and full sun. Keep the soil moist deep down by soaking it with a hose for half an hour, but letting it dry out in between waterings. Care for a jacaranda tree almost always includes pruning. In order to give it the best shape to show off those blooms, smaller branches should be trimmed early in the spring. Clip off suckers that grow vertically and keep one main trunk with some major branches leading off from the middle. Keep excess branches cut, to prevent the weight of the tree from splitting the trunk.
