cannonball tree

Couroupita guianensis

Overview

The Cannonball Tree is an amazing species known for its huge, bright, fragrant flower clusters. Its woody capsule fruits are similar in size to a cannonball which is where it gets its name. This tree is very hardy and can adapt to various climates and soil types but prefers areas that tend to be moist and humid. Its flowers give off a sweet aroma and often attract hummingbirds and other pollinators to the garden. It's a fast-growing and ornamental tree that is perfect for those looking for a tropical look for their landscape. Plus, its non-toxic fruits are said to have medicinal properties.

Care Guide

💧

Watering

Water the cannonball tree regularly and profusely, as it does not do well with dry soil. During its growing season (Spring to early Summer), it should be watered twice a week. This is especially important if the tree has been recently planted. During the dormant season in late Fall and Winter, reduce watering to once a month. When in doubt, use your finger to check the soil's moisture level. If it feels dry to the touch, it's time to water.

☀️

Light

The cannonball tree needs at least 6 to 8 hours of direct sunlight per day. This is because it is native to regions close to the equator, and it requires the immense energy of direct sunlight to grow the large fruits it is known for. The best time of day for the cannonball tree to receive sunlight is between 9AM and 4PM or 10AM and 5PM when the sunlight is most direct.

Cannotball Trees should be pruned quite lightly, removing only dead or weak branches and cutting back branches that are too close together. The amount of pruning should gradually increase as the tree matures.
