Remove seeds from a mature kiwi fruit and allow them to dry out. This may take a couple days.
Place seeds in a moistened paper towel, store in a plastic bag and keep in the refrigerator at 40 degrees F. for three or more weeks. This is called stratification, and can be continued for four months for better germination results.
Fill seedling tray with sterilized potting soil and place seeds 1/8 inch deep. Provide moderate water to keep the soil moist. Germination can occur in three weeks if soil temperature is 65 to 76 degrees F. Maintain a high humidity level for best results.
Transplant seedlings to 3- or 4-inch pots once they grow three to four true leaves. At this point a temperature range of 60 to 75 degrees F. is ideal.
Plant seedlings in the ground when they reach 3 to 5 inches in height or once frost danger is past. Space plants 3 feet apart. For container growing, move to larger containers at any point. An ideal planting location is one with slightly acidic soil, between a pH of 5.5 and 7.0, that is moist and organically rich.
