How Long Does It Take to Germinate Hardy Kiwi From Seed?

Germination Time

• The fruit contains small-sized seeds that may be removed from fresh fruit and used for germination. To separate seeds from fresh pulp, peel the fruit and blend at a slow speed. Place pulp in a pan and add water. The pulp will float to the top and the seeds will sink to the bottom. Under optimal conditions, seeds that have first been stratified for four to six weeks germinate in about three weeks when kept at 65 to 76 degrees Fahrenheit.

Preplanting Treatment

• For effective germination, it is important for kiwi seeds to go through a preplanting treatment referred to as stratification. Stratification mimics the cold weather that native fruits of Northern and temperate habitats naturally require to break dormancy prior to germination. To stratify, half fill a small container with moist peat moss, sprinkle seeds on top and cover with a light layer of peat moss. Place the container in a plastic bag and leave in the refrigerator for four to six weeks.

Growing Medium

• Remove the container from the refrigerator after the stratification period, uncover and place the entire container in a warm spot. Make sure the peat moss remains moist but not wet. It will take about three weeks for germination. After seeds have germinated, move the container to a bright window and let the seedlings get 2 inches tall. Fill 4-inch pots with moist potting soil, lift out individual seedlings carefully and transplant. Plant deep enough for the soil to come an inch up the stem. Water well. Let the plants get sturdier before planting to a permanent outdoor location.

Cultural Requirements

• Plant hardy kiwi in a well-drained, lightly acidic soil with a pH of 5.0 to 6.5. Avoid planting in salty or neutral soil. Select an area receiving full sun and protection from high winds for best growth. Keep the plants well watered throughout the entire growing season, especially during summer. The plants have a high requirement for nitrogen and, once established, are tolerant of temperatures as low as minus 25 degrees Fahrenheit.
