Planting and Caring:
The jacaranda is moderately drought-tolerant but requires watering during dry periods. If the tree is not watered deeply enough, it may not produce enough chlorophyll, causing chlorosis.
For the best blooming, plant the jacaranda in full sun. Small trees can live in light shade if necessary.
The tree will do best in well-draining, moderately sandy soil with a slightly acid pH. It is tolerant of clay, loam, and sand but should not be planted in wet soil. Make sure the soil drains properly, or mushroom root rot may develop.
As a general rule, water your jacaranda tree when the top 3 inches of soil has dried. These trees need consistent moisture throughout the year and often require additional watering during periods of high heat and/or dryness.
You can feed a jacaranda annually with a compatible tree fertilizer, but be careful not to give it too much nitrogen, which can cause the tree not to flower. If you are fertilizing grass under the tree, chances are the tree is getting a lot of nitrogen already.
