Our recommendation ::
All four of the new macadamia varieties have been trialled at different farms in the Northern Rivers area and Bundaberg. Soil type, slope and other local factors can have a significant impact on the performance of macadamia trees. It is recommended that you plant your new macadamia orchard out in two stages.
We do not have a rootstock recommendation. Each variety was trialled with both current industry rootstock options – H2 and Beaumont. H2 is generally more widely available as a rootstock material than Beaumont.
We suggest you plant a small number of test trees (30-200) of each of the four new varieties to provide an assessment of the best performance at your farm location.
Scale up your orchard planting based on the best performing of the four new high-yielding varieties.
Of course, if you are confident in the performance of your chosen new macadamia varieties in your soil type, then consider planting a whole block from the outset.
