Mac Nut Tree Pruning. I have several mac nut trees on my property.
In Hawaii, the nuts typically drop months of the year from July to March.
They need to be pruned. When should it be done? It seems like it might already be too late. Anyone know a good company to do it? I also have the same thing with lychee. That I guess won't happen until July after the fruit shows up this year. Macadamia nut trees can be grown on deep, well-drained soils with a pH of or on well-drained a'a lava land that is sufficiently weathered to support natural vegetation.
The trees require inches of rainfall a year and can be grown from sea level to an elevation of feet. Prune macadamia nut trees to a central leader and so scaffold branches are spaced 6 inches apart and zig-zagged up the tree (not on top of each other.) One you have created the basic shape little pruning is needed.
However cut back branches that go in wrong directions back to your strong laterals. If you have trees with very dense canopies that have not been opened up, remove 1–3 upright limbs in the center to allow more light into the tree. Use thinning cuts to open up the canopy so that light penetrates all parts of the tree. Trees with very open growth habit, such as Yamhill, require less pruning and have naturally wide branch stumpmulching.barted Reading Time: 6 mins.
