Depending on the cultivar rootstock is multiplied via cutting propagation and or seed germination. Source material for Bounty71 and Bruno rootstock cultivars is produced in house or acquired from Plant and Food Research to provide maximum genetic credibility. During propagation we control air and soil temperature, humidity, soil moisture, and nutrient intake to help achieve maximum success and healthy plant root systems.
Once the propagated rootstock has a healthy root system and is nearing capacity of the propagation trays we carefully pot into larger planter bags to promote root expansion. During this phase we feed the plants daily during watering and control the climate to suit plant growth. In this environment the young plants quickly produce new growth which is trained up bamboo stakes.
Once a strong shoot has extended high above the bamboo stake on each plant we cut back and graft on the desired variety using a variety of grafting techniques. Our graft wood is collected from the South Island to maintain maximum credibility of being PSA free. Each orchard is sampled for PSA pre collection. The new grafts knit quickly in controlled climates and begin growing up the bamboo stakes where they are pruned to promote graft thickness.
