Unique Seedling Rootstocks


Rootstock has profound effects on traits such as yield and tree size in various horticultural industries.

Our macadamia trees are produced as varieties grafted onto N2, H2, 695 (Beaumont) seedling rootstocks.

N2 is precocious and has excellent adaptability to regional conditions.  H2 and 695 are currently the most common rootstock cultivars globally, based on tree growth rate as well as kernel recovery, canopy width, canopy efficiency, (yield per unit canopy area), Phytophthora resistance attributes.

The H2 Hinde variety (Macadamia integrifolia) is the dominant macadamia rootstock kept by Australian nurseries.  It is estimated that 90% of all grafted Australian commercial trees stem from H2.
