When to plant
Plant in spring after last frost. Hardy kiwi (Actinidia arguta): cold-hardy to zone 3, produces grape-size smooth-skinned fruits. Fuzzy kiwi: zones 7–9. Both require male and female plants unless self-fertile. Takes 3–5 years before first fruit. Life span of 30–50 years once established.
Soil & site
Rich, well-drained, deeply prepared soil. pH 6.0–6.5. Amend with generous compost. Excellent drainage is critical — kiwi roots rot in wet soils. Install a very sturdy trellis or pergola before planting — mature kiwi vines are extremely heavy and vigorous.
Feeding
Moderate to heavy feeder. Apply balanced fertilizer in early spring. Add a nitrogen-rich fertilizer in late spring during rapid growth. Switch to a lower-nitrogen, potassium-rich fertilizer in midsummer. Avoid late-season nitrogen, which promotes tender growth susceptible to frost damage.
Common problems
Scale insects, root rot in wet soils. Deer and rabbits browse young vines. Cats are strongly attracted to the vine (similar to catnip effect). Crown rot. Frost damage to early spring blossoms is a primary yield limiter. Most fuzzy kiwi varieties need a male and female plant for pollination.
When to harvest
Kiwis do not ripen fully on the vine — harvest when physiologically mature (firm) and ripen off the vine at room temperature. Pick in fall after the fruit reaches full size and shows its mature color. For fuzzy kiwi: squeeze gently — a mature kiwi feels firm but not rock-hard. For hardy kiwi berry varieties: fruit is ripe when it turns slightly soft and sweet on the vine.
How to harvest
Clip individual fruits from the vine with pruners, leaving a short stub of stem. Handle gently to avoid bruising. Harvest before hard frost, which damages fruit. After picking, store at room temperature for 3–7 days until slightly soft. Speed ripening by placing with an apple.
Storage & use
Unripe (firm) kiwi: store in the refrigerator for up to 2 months. At room temperature: ripen in 3–7 days. Ripe kiwi: refrigerate and use within 1–2 weeks. Freeze: peel and slice before freezing. Dried kiwi chips are a good preservation option.
