The kiwi plant is a fruit bearing, deciduous vine that is native to Asia. According to Oregon State University, the most commonly grown kiwi fruit is the variety acitindia deliciosa, which is also referred to as the Chinese gooseberry vine. The acitindia deliciosa variety is hardy in the USDA Zones 4 to 9, and can tolerate temperatures down to 10 degrees F. All varieties of kiwi fruit and require ample room to grow, and support for the vines such as a trellis. Kiwi are very vigorous growing vines, often growing between 6 and 12 feet a year. Plant kiwi vines where they will receive full sun and provide them plenty of water.
Preparing the Seeds
Separate the pulp of the kiwi fruit from its seeds. You can do this by pulverizing the fruit, then forcing the pulp through a strainer. Once you separate the seeds from the pulp, wash the seeds off thoroughly.
Place the kiwi seeds onto a few sheets of paper towel to dry for two days.
Dampen down 1 to 2 cups of perlite. Place the perlite into a zipper top polythene bag. Add the kiwi seeds to the polythene bag and squeeze out excess air as you seal the bag closed. Shake the contents of the bag gently to distribute the kiwi seeds into the perlite.
Set the bag in your refrigerator, or where the temperature will remain at a fairly constant 40 degrees F. Leave the bag in the cold storage location for four months. Open the bag every three to four days to spritz the perlite with water.
Remove the bag from your freezer after the four months has passed. Sow the kiwi seeds into a nursery flat.
Sowing Kiwi Seeds
Fill up nursery flats to within 1/2-of-an-inch of the rim with a good-quality sterilized seed starting compost. Make sure the seed starting compost is thoroughly moistened down and packed. Scatter the perlite and kiwi seed mixture across the surface of the soil in the nursery flat so that it's evenly distributed to a depth of 1/8-of-an-inch.
Firm down the perlie and seed mixture gently using the bottom of a 4-inch pot, a block of wood or the back of a spoon. Cover the nursery flat either with a sheet of glass, or clear plastic wrap. If using clear plastic wrap, make sure the wrap does not come in contact with the growing medium.
Place the nursery flat with the temperature will remain between 70 and 75 degrees F. Also try and provide about eight to 10 hours of light every day, but try and avoid direct sunlight. Keep the growing medium in the nursery flat well moistened. Spray the surface of the soil with water as needed. Germination of kiwi seeds is anywhere from three to four weeks. As soon as seedlings emerge, remove the glass or plastic wrap.
Transplant the kiwi seedlings when they grow to about 3 inches tall. You can plant them directly into your garden, or into growing containers and grow them indoors as a house plant.
