This grafted tree produces medium to large nuts with an excellent kernel recovery, buttery flavour, and cracking ease. It has been selected for high yield and strong disease resistance, especially to husk spot and trunk cankers. Growth is upright and moderately vigorous, making it suitable for pruning or small spaces.

A203 prefers well-drained soil enriched with compost and minerals. Mulch well and avoid waterlogging. It grows best in mild to warm climates, with light frost tolerance once established. In sandy soils, add clay, compost, and trace minerals like boron and calcium for stronger flowering and nut set.

This is one of the top three macadamias grown in Australia for productivity and nut quality. If you’re after a reliable nut tree that doubles as a beautiful evergreen, A203 is a safe bet.
