Breonadia salicina grow relatively fast from seeds. In preparation to sow seeds, use a large-sized seed tray, sterilize and fill the seed tray with coarse bark underneath for sufficient drainage, then fill the tray with river sand, level the surface and sow fresh seeds on the surface and slightly cover with river sand and keep moist. The rate of germination is usually between 60–80%. When the seeds have germinated and the seedlings have reached the 3 leaf-stage, transplant the seedlings into 9 cm nursery pots filled with a mixture of river sand and compost (ratio of 5 parts sand and 1 part compost) and place in a shady, humid, moist area. Transplant the seedling when the roots have developed sufficiently, into a larger container or bag, preferably 10 litre nursery bags, filled with the same soil mixture (5:1) and possibly add slow-release fertilizer, to enrich your soil. Harden off in a partial shade to full sun area.

Matumi grows in most well-drained soil types, provided that there is sufficient water. It can grow with its roots in water, but will not thrive in boggy, water-logged soil. The leaves tend to respond immediately by wilting with lack of water. It is frost sensitive, but can withstand cold conditions.

When planting this tree, dig a hole twice the size of the root ball, prepare a mixture of dug-out soil, with preferably an organic fertilizer and compost and start planting. Remove the container without disturbing the roots and add some of the mixed soil into the hole and the remainder around the root ball and compact. Ensure that the root ball is at the same level as the original ground surface. After planting, water regularly until the tree is established in the ground.
