Cannonball tree: How to grow?

The Cannonball tree (Couroupita Guianensis) is a tropical tree native to the Amazon rainforest in South America. It is known for its large, round fruits that resemble cannonballs, hence its common name. To grow a cannonball tree, follow these steps:

  1. Choose a location: A cannonball tree requires a warm, humid environment and prefers full sun to partial shade. It is not frost-tolerant, so it should be grown where temperatures do not drop below freezing.
  2. Prepare the soil: Cannonball tree grows best in well-draining soil with a pH of 6.0 to 7.0. If your soil is not suitable, you can prepare a mixture of equal parts compost, peat moss, and perlite or sand.
  3. Plant the tree: Cannonball trees can be propagated by seed or by planting a small tree. If you are planting a small tree, dig a hole twice as wide as the root ball and as deep as the root ball. Place the tree in the hole and fill it with soil, making sure to tamp it down firmly to eliminate air pockets. Water the tree thoroughly after planting.
  4. Water and fertilise: Cannonball trees require regular watering, especially during the first few months after planting. Water the tree deeply once a week or more frequently if the soil becomes dry. Fertilise the tree with a balanced fertiliser once a month during the growing season.

By following these steps, you can successfully grow a Cannonball tree in your garden.

Cannonball tree: Flowering season

The flowers of the Cannonball tree are lovely. The intense and enticing scent of the enormous rose-pink blossoms is strongest in the mornings.

Each one only lasts for one day and has six spreading petals surrounding both fertile and sterile stamens. The fruits that give the Cannonball tree its name are produced by the pollinated blooms. The fruits develop on the vines as well.

Over the course of 18 months, they grow into enormous, spherical balls about the size of cannonballs. On windy days, the fruits, which are woody and reddish brown, bang against one another and make a cannonade-like sound.

When the fruit is ready, it explodes when it hits the ground after falling from the tree. The many seeds inside the fruit can occasionally be seen when the fruit cracks apart.
