    First, make sure your jacaranda tree is growing in an appropriate environment for the species. Jacarandas need well-drained, preferably sandy soil, and they flower best if their soil is not very rich in organic matter.

    Also, exposure to excessive nitrogen fertilizer or lack of phosphorus in the soil can cause many plants to flower poorly.

    If grown from a cutting, they can take 2-4 years to bloom, but if grown from seed, they can take anywhere from 5-14 years to flower depending on their genetics and the planting location.

    Jacarandas seem to be picky about the environmental conditions they are grown in. They are more likely to produce flowers if they're in full sun, have well-drained, sandy soil, and are not exposed to a lot of wind. The flower buds can also be damaged by cold winter weather.

    Jacaranda Trees can suffer damage when exposed to temperatures below 26 degrees F.

    You can check the tree by bending the branches. Do they snap off or bend?
    Scratch the bark. Is it green underneath?

    The roots may be unharmed and you can give the tree time to see if it can recover.

    Here are some links to help you.

    Yellowing leaves is generally an indicator of a watering issue, especially in a newly planted tree.
    Make sure you have correctly placed the tree and that you are watering correctly.
    Soil should be kept moist. You will need to be checking the soil instead of watering on a schedule.
    The amount you mention is not likely enough.

    The bark splitting could be due to environmental issues; sun scald, exposure to cold temperatures.
    Check for signs of insects or disease; developing Canker can cause the trunk to split. Is the tree oozing and material?
    The symptoms that the tree itself is showing can help determine a cause.
    A soil test will help you determine if the plant is suffering from a nutrient deficiency, though the Jacaranda does well in poor soil. It will not tolerate clay or poor draining soil.
    A poorly growing Jacaranda can benefit from a fertilizer application of a granular 12-4-8 ratio. Apply when the new growth begins to appear in spring and every 3 months until fall.

    Do not over fertilizer.

    Consistently moist soil is important, an established tree can withstand some dry spells.

    Fertilizing late in the season can cause to rapid of growth and a trunk to split.

    Research shows the the best flowering on a Jacaranda occur following a winter with temperatures above the 30's.
