Actinidia aruguta Kiwi arctique espespesp
Perennial hardy plant
Soil : Kiwifruit can be grown in any garden soil provided the pH is between 5.5 and 7.0. The plants thrive in moist soils but do not tolerate poorly drained soils. They benefit from incorporation of organic matter before planting.
Frost tolerant :
Sow and Plant : At least one male plant for every nine female plants to ensure pollination and fruit set.Avoid planting in frost pockets. Sites with northern exposure are good because they delay early growth in spring, which can be damaged by late frosts.Construct a trellis system or otherwise support vines.Prune plants at least two or three times during the growing season and once during winter.
Kiwifruit can be propagated from cuttings or seeds. Take hardwood cuttings anytime after the plant has received 500 hours of chilling, or make softwood cuttings in July. Kiwifruits can also be propagated by layering. To grow plants from seed, remove the seeds from a mature fruit and let them dry for two days. Refrigerate them in moist perlite at 40° F for four months. Then plant the seeds no deeper than 1/8 inch in a sterile potting mix and cover the container to keep the humidity high. The soil should be moist but not wet. As soon as the plants germinate, uncover the container. After the seedlings are up, put a thin layer of clean sand on top of the medium. When plants have four true leaves, transplant them to individual pots. At this time, use a low rate of liquid fertilizer. Transplant the seedlings to where they will grow when they are several inches tall.
Spacing : 10 ft apart
Harvesting : in early summer, the vines bear small white flowers with chocolate-colored centers on the previous season’s spur growth. Plants usually fruit by their fourth year, and bear full crops after the eighth year. Once established, plants can live for fifty or more years. Kiwifruit will not reach maturity and flower until about their fifth year. Fruit matures in October,
Time to harvest: days
Notes : Pruning is necessary both during the dormant season and during the growing season. Two or three times during summer, cut non-flowering laterals back to the outside wire on the trellis. Trim flowering shoots back to 4 to 6 leaves beyond the last flower. In the dormant -season, remove canes that fruited last season, as well as dead, diseased or tangled cane. Keep the best one-year-old lateral canes that haven’t fruited, spaced about a foot apart along the arms. Trim them back to about eight buds. Plants benefit from a thick layer of organic mulch, which helps control weeds, adds organic matter to the soil, and aids in moisture retention. Protect the trunks of young vines from cracking in cold temperatures by wrapping them with cloth or painting them with white latex paint.
