How to Germinate and Grow Kiwi Seeds


The vines that produce kiwifruit, known scientifically as Actinidia spp., grow quickly and yield fruit that is high in vitamin C. The kiwifruit vines have to be trained to climb on a trellis or a wall, and unless you have a kind that can fruit on its own, you need to have a pollinator close by.

According to the University of Wisconsin Master Gardeners, the most common varieties of kiwifruit grown in the United States are Actinidia arguta (USDA hardiness zones 3 to 8) and Actinidia kolomikta (zones 4 to 8). Kiwifruit are native to Asia and their hardiness varies depending on the zone in which they are grown. Because it can thrive in a wide range of climates, the arguta species of kiwifruit is often referred to as “hardy kiwi.”

Growing kiwis from seed may be a gratifying endeavour, despite the fact that their traditional method of propagation involves cuttings. You won’t be able to discern the gender of the plant from the seeds, thus it’s important to grow more than one of them. The Oregon State University Extension recommends having at least one male kiwi plant for every six to ten females in order to ensure successful pollination. According to Walter Reeves, the blooms of female and male plants provide the principal means of distinguishing between the two types of plants. Because male flowers contain pollen, the centres of their blossoms are yellow, whereas the centres of female flowers are more white.

  1. 1. Extract the seeds from the fruit

    Using a knife, split open the kiwifruit, then remove the seeds from the inside using a spoon. Put them in a sieve, and while applying some little pressure to the strainer, separate the pulp from the seeds. To clean the seeds, just run clean water over them very briefly, and then let them air dry on a paper towel for two days.

  2. 2. Refrigerate the seeds for four months

    Place wet perlite in the lower part of a plastic bag that may be sealed. After giving the seeds a little prod into the perlite, close the bag tightly and store it in the refrigerator at a temperature of around 40 degrees Fahrenheit for approximately four months. To maintain the perlite’s moisture level, use a spray bottle filled with water to give it a little misting whenever it’s required.

  3. 3. Plant the seeds

    Put wet, sterile potting mix in a seed-raising tray until it’s about 3/4 of an inch away from the top. The surface may be made even by tamping the dirt. Take the kiwi seeds out of the refrigerator and scatter them over the top of the soil where they will be planted. After spreading the seeds out in the tray, add an eighth of an inch of potting mix on top of them and give it a quick tamping to compact it.

  4. 4. Keep the seeds moist

    Spray water onto the top layer of the soil. During the time when the seeds are germinating in the soil, you should strive to maintain a wet but not soaked soil. In order to preserve the appropriate amount of humidity, cover the tray with either plastic wrap or a pane of glass. Put the tray in a warm place, and after about four to five weeks, you should see the seeds start to sprout.

  5. 5. Thin and transplant the seedlings

    After the kiwifruit seeds have germinated, remove the plastic and place the tray in a window that gets plenty of sunlight. Reduce the number of seedlings until only the healthiest are left. After the final date that frost is expected in your region, transfer them outdoors as soon as they are grown enough to be handled.

  6. 6. Prepare the planting location

    In the part of the garden that gets the most light, till the soil. You may use your hands or a garden hoe to get rid of any weeds. Compost may be worked into the soil at a depth of 2 inches to increase drainage and the availability of nutrients. To achieve optimal growth conditions, the soil’s pH should be adjusted to a range between 5.5 and 7.0.

  7. 7. Transplant the seedlings

    Plant the young kiwifruit seedlings in the ground outdoors next to a trellis, fence, wall, or patio so that they will have something to climb on. Make sure there is at least 10 feet of space between each plant.

  8. 8. Maintain moist soil

    A minimum of one inch of water should be applied to the kiwi plants each week, and as much as two inches of water should be applied when the temperature is really high. During the growth season, it is important to prevent the soil from being entirely dry. Mulch the soil around the plants with a layer of seed-free straw that is at least 4 inches thick to help the soil retain moisture and to prevent weeds from growing. It is important to provide a gap of at least 1 inch between the mulch and the top of the plants.

  9. 9. Fertilize the plants

    The kiwifruit should be fertilised with a 10-10-10 mixture beginning one year after the seedlings have been moved outdoors and continuing every year after that.
