What is macadamia nut farming?

Macadamia nut farming is the practice of growing macadamia trees to harvest their nuts. Macadamia nuts have an outer covering that starts with a bright green color, and as it ripens, it transitions to a dark forest green color. Once the covering is fully ripe, it splits open to reveal a cream-colored nut with a buttery flavor. Additionally, macadamia nuts are known to have the toughest shell of all nuts, which requires a lot of force to crack open. They can also come in different colors such as green and brown.

Macadamia nut farming has become increasingly popular in recent years due to the high demand for the nut. The farming process typically involves planting the trees, providing appropriate irrigation and fertiliser, pruning, protecting them from pests, and then harvesting the nuts.

The macadamia nut tree is native to Australia but is now grown in a variety of locations worldwide to meet the global demand. In South Africa, macadamia nuts are primarily produced in Levubu and Tzaneen in the Limpopo Province, Hazyview in the Mpumalanga province as well as the coastal KwaZulu Natal. The industry in South Africa has grown significantly in value over time.

Macadamia trees require a hot non-humid subtropical climate. The South African macadamia industry is export-based, with the majority of the nuts being exported to Asia and Europe. The processing of macadamia nuts in South Africa involves hand-picking, dehusking, drying in in-shed systems, cracking, sorting, grading, and packaging.

Macadamia farming has become a popular business in South Africa due to its high profitability. The nuts have high demand both locally and internationally, with the latter being the primary market.

Overall, macadamia nut farming is a viable and lucrative business that is growing in popularity.
