For bare rootstock, set the root crown just below the ground soil surface. The trees flower during spring from August to September. Main crop areas are Hawaii, Australia, South Africa and Central America. It also helps to maintain a ground cover of grass or similar suitable plants. The irrigation system can also be placed into position. ARC-Institute for Tropical and Subtropical Crops Each tree position should be accurately marked using a level distance. This is to ensure proper soil root contact as soil washes into the plant medium and air is removed from the immediate soil volume around the tree and the plant medium. Otherwise, soak the macadamia seed for 48 hours in a bowl of room-temperature water. This is the only stage where any root pruning needs to be done between germination, and planting the tree.

The Some growers looking for early returns plant trees in rows as close as 5m apart, with 2.5m between trees within rows. well established and start growing vigorously before any applications are made, Set-up costs may be less with this spacing, but time to achieve a financial return is longer. Macadamia trees are very sensitive to root damage, therefore each Reference points such as a road or a wind break can be used to create a base line for the rows, or base lines can also be referenced on the irrigation design, the land contour or a fence. 3 main aspects to be considered before planting an intercrop. Macadamia trees will produce kernel recoveries in excess of 30-35%. Picture 2: The planting jig with two reference pegs at both sides of the tree position peg. When the base line is decided on, peg out the tree rows at an 8m distance every 100m. The stake should be placed at a 45˚ angle. Over a ridge or through a gully, it is more accurate by sight than by using a measuring tape or a marked cable/rope. South Africa remains the world’s largest macadamia nut producer, having produced 44890 tons of nut-in-shell(1.5% kernel moisture) in 2014, while Australia(where they originated) ranked second. There are two ways to go about growing macadamia trees – cutting and grafting. If a very strong root is detected at the very bottom of the medium, with a sharp bed or kink, it can be pruned. Of course the latter option is somewhat faster but might entail a risk factor because you might not be sure if these seedlings were nurtured properly. To start growing macadamia nuts you can either start off with the seeds or you can source seedlings. Basic requirements Macadamia trees originate from the sub-tropical rainforests of Australia and therefore tend to grow best in areas of high humidity and high rainfall. They are regarded as superior to Nelmak 1 and Nelmak 2 for Most soil types are suitable for the production of macadamias, provided they are Diagram 2 shows how measuring along the slope actually pulls the tree positions closer, compared with the distance measured at perfectly level.

The South African market is largely driven by exports and, as demand increases, we have seen hectares under macadamias trees increasing rapidly in South Africa's macadamia growing areas. Other growers plant as wide as 10m between rows, with 5m between trees within rows, giving a stocking of 200 trees/ha. By keeping the tree at a height of 75% to 80% of the row width using pruning, light is allowed on to the entire tree length, as well as on to the soil. commercial processing and marketing.

These small differences over a few hectares pull the tree rows askew and out of square, especially diagonally. Do not fertilise young, transplanted trees too soon. Fertilisers must not be worked into the soil. Those who dig the holes can also install the reference pegs. Once all the trees are planted the tractor can hook up the water bowser and fill each base-dam with water. As soon as the competition for light becomes too great, production will decrease. Where the slope gets steeper than between 5% and 8 %, row direction should follow the contour as closely as possible. Poorly-drained This will eventually allow for a 2m to 2.5m work area, where tractors and implements can move between the rows with ease.

Specialist consultant and owner of Advanced Macadamia Consulting Kobus van Niekerk details the best way to plant macadamia trees in a newly prepared orchard. Height above sea level influences nut quality and production. The planting team is followed by a worker who builds a dam at the base of the tree for watering purposes. either burrow into the green husks of macadamia nuts or feed on the kernels. Under ideal circumstances the crack-out percentage will be higher than 40 %. used. Row direction must be decided upon according to soil types, erodibility, topography or access to light. Tree spacing that balances the health of the orchard and pragmatic economic sense is 8m between the rows and 4m between the trees in the row. This can be done by workers doing the planting. Behind those putting in the pegs, workers will dig a hole for planting. In Picture 1, the tree position pegs can also be seen in straight lines in all directions. Macadamia trees reach 20 metres but if you've got limited space consider the new dwarf varieties that are much smaller. Make a collar of dirt about two feet out to help with moisture retention. Macadamias grow on a a wide range of free-draining soils but perform best on deep, well-drained soils, rich in organic matter. When the trees are established and start growing, fertiliser must be applied They will grow optimally at average annual temperatures between 20 and 25°C (68–77°F) in a deep, well draining loam and sandy loam with a pH between 5.0 and 5.5.

South Africa is a net exporter of macadamia and pecan nuts. Macadamia tree takes five to twelve years to produce nuts and a good tree can produce nuts for 40 years. regularly according to the table. China currently consumes about 30% of South African macadamia production. There are a number of cultivars. Step 2 Choose a 12-inch-deep germinating container for the macadamia tree seed. Planting macadamia nut seeds in this manner allows the taproot to form properly. This maximises sunlight interception on both sides of the tree rows, particularly during winter. A hill or a slope pulls the distances closer. is caused by a stinkbug complex comprising at least 20 different types. winter and spring generations when morning temperatures are low.

Kau and Keaau. of macadamia nuts. importance. Fertiliser must be broadcast evenly from about 0,2 m from the stem to about 0,5 m outside the drip area of the tree. Once all the tree positions have been pegged, making sure the exact positioning is maintained, put in two reference pegs using a wooden plank jig as illustrated in Diagram 3. The cultivars recommended are: Keaau, Kakea, Kau, Purvis, Pahala, Mauka This distance limits the tree growth to between 6m and 6.5m. Farmers are now making more use of GPS-guided tractors with a single tine tooth implement, drawing shallow furrows at regular intervals (8m or 16m) in a grid. The global industry is quite small, with macadamia nuts accounting for just over 1% of the total tree nut volumes produced internationally. To allow for tractors to move between the trees, the hedgerow planting system is Lemmer (2017) identifies tree nuts as an area for import substitution. Four or more identical jigs are necessary: two for the workers putting in the pegs and those digging the holes, and one with each planting team (at least two jigs per team). 5 Ha are arable land planted with mature macadamia trees , has canal water rights , and are under micro irrigation. • The orchard is 20 hectares of trees planted at 8 m x 4 m or 312 trees per hectare. • The orchard is not irrigated.
