Position – Select a location in your yard that gets full sun but has shelter from the wind. The south or west side of a less windy garden is most suitable.
Size – Macadamia nut trees can grow to between 2 and 12 metres tall in the garden, but they can be grown in large containers too.
Soil – These trees favour acidic to slightly acidic soil that drains well. If your garden soil is not deep, well-draining and fertile, use perlite or sand.
Because they like slightly acidic soil, use a bag of acid compost. Firm the soil around the roots to eliminate air spaces and water deeply after planting to help lessen the shock of transplanting. Add as much organic matter or compost as possible to the hole or pot before planting.
Mulch – Mulching is important to preserve moisture, as macadamia nut trees require slightly moist soil. Mulching also prevents competitive weeds—mulch with crushed, dry leaves or acid compost.
Harvesting – Collect your nuts every few weeks in the wet weather. They are ready to be harvested when their outer shell cracks or when they fall to the ground.
