Jacaranda trees love sun, and thrive when they receive 6 to 8 hours of direct light a day.
Water deeply but infrequently, once a week, or more during very hot or drought-like weather conditions.
Jacarandas like poor soil, so should only be lightly fertilized, if at all, with a balanced, 10-10-10 tree fertilizer.
Planting and Care
Jacaranda trees prefer a planting site with sandy, well-draining,soil that receives full sun. Also consider that the tree will drop a large amount of flowers, creating yard litter that may need to be raked. When you’ve found the perfect site, dig a hole as deep as the tree’s root ball and about three times as wide. Place the tree upright in the hole, making sure the top of the root ball is level with the ground, and backfill with soil. Gently tamp down the soil and water the planting site thoroughly.
Watering and nutrients
For a few weeks after planting, Jacaranda trees should be watered every couple of days. Be careful not to oversaturate the soil, as this can lead to fungal diseases, root rot, and slow growth. Once the trees have established themselves, they should only require supplemental water during long periods of drought. Jacaranda trees thrive in poor soil, and rarely need supplemental fertilizing. At most, give your tree a light application of a fertilizer formulated for landscape and flowering trees.
Jacaranda trees do not require much pruning to grow successfully. There are a few instances where you may wish to break out the pruning shears and trim up your tree. Always remove dead, dying, or diseased branches as soon as you find them, as these can slow down growth or spread a disease to the rest of the tree. You may also wish to prune lower branches if the tree is blocking a pathway, or to promote a denser, wider canopy. Pruning is best performed in winter during the tree’s dormant period.
Pests and diseases
Watch out for glassy-winged sharpshooters, a leafhopper insect, as they carry a bacterial disease called Xylella fastidiosa that will kill your Jacaranda trees. If you spot this pest or see evidence of their presence in the form of a white fluid on your tree, apply neem oil or insecticidal soap to your tree’s foliage. Like many plants, Jacaranda trees are prone to aphid infestations. Lady beetles are the best defense against aphids, but you can also apply neem oil as an effective remedy. When planted in soil that lacks adequate drainage, Jacaranda trees will likely develop root rot.
Are Jacaranda trees fast growing?
Jacaranda trees are prolific growers, usually putting on three to four feet of annual growth. Individuals planted in ideal conditions have been known to grow over six feet per year. Mature specimens can grow to towering heights of over 50 feet with a canopy spread of up to 30 feet. Jacaranda trees planted in a favorable environment may live for over 150 years, but the average lifespan for the species is around 50 years.
Can Jacaranda trees be grown in containers?
While growing Jacaranda indoors is possible, it comes with a few challenges. The tree requires large amounts of direct sunlight, which can be impossible to provide in some homes without the addition of grow lights. If you can meet the tree’s light requirements, make sure to plant in as large of a container as you can accommodate. Jacaranda is also a popular choice of tree for bonsai growers.
When do Jacaranda trees bloom?
Depending on the area they are grown in, Jacaranda trees will bloom in late spring or early summer. Once bloom season arrives, the purple flowers may last on the tree for up to two months. This long period of beauty is what has made the species so popular. Expect to see blooms on your Jacaranda trees three or four years after planting — the first round of flowers may take longer to appear if the tree is planted in unfavorable conditions.
What is the purple panic?
In many parts of the world, the blooming season of Jacaranda trees lines up with the end of year exams for students. Many colleges, especially in Australia, have many Jacaranda trees planted around their campus. For students on these campuses, the trees’ purple blossoms have become associated with the stress that comes with finals and exams. Hence, this period of time is known as the purple panic.
