Growing your own kiwi fruit can be a rewarding and enjoyable gardening adventure. These delicious, vitamin-packed fruits are not only tasty but also add a lush, tropical vibe to your garden with their vigorous vines. If you’ve ever wondered, how do you grow a kiwi? – this guide will walk you through the process step-by-step, from planting to harvesting, in a simple and friendly way.
Choosing the Right Kiwi Plant
Before you start, it’s important to know that most kiwi plants are dioecious, meaning male and female flowers grow on separate plants. To get fruit, you’ll need at least one male plant for every five female plants. If space is limited or you want an easier option, look for a self-fertile variety like ‘Jenny’ that doesn’t require a male pollinator.
Where to Plant Your Kiwi
Kiwis love a sunny, sheltered spot with well-draining soil. Ideally, choose a location that gets full sun and is protected from strong winds. A south- or west-facing wall is perfect because it provides warmth and shelter, helping the vines thrive.
The soil should be slightly acidic and fertile. If your soil is alkaline, you can amend it with organic matter or use soil improvers designed for acid-loving plants. Good drainage is crucial because kiwi roots don’t like to sit in water.
Preparing the Soil and Site
Before planting, enrich the soil with plenty of organic matter, such as well-rotted manure or compost. This will provide nutrients and improve moisture retention without waterlogging the roots. Raised mounds or beds can help with drainage if your garden soil is heavy.
Make sure you have a sturdy support structure ready, like a pergola, fence, or trellis, because kiwi vines are vigorous climbers and need space to spread out. Each vine can grow up to 20 feet, so plan for plenty of room-spacing plants about 10 to 18 feet apart is ideal.
How to Grow Kiwi from Seed or Plant
Growing from Seed
If you want to grow kiwi from seed, start with a ripe, preferably organic kiwi fruit. Scoop out the seeds and clean them thoroughly. You can blend the pulp with water briefly to separate the seeds, then rinse them in a sieve.
Sprinkle the seeds on moist sand or a damp paper towel inside a plastic bag and keep them warm. Germination usually takes about two weeks. Once sprouted, transfer seedlings to pots with well-draining potting mix and keep them in a sunny spot.
Seedlings take time-expect 3 to 5 years before fruit appears. Also, remember you’ll need male and female plants for fruit production unless you have a self-fertile variety.
Planting Kiwi Vines
The best time to plant kiwi vines is in spring when the soil has warmed. Dig a generous hole, mix in compost or manure, and plant at the same depth as they were growing in their pots. Water well after planting.
If planting male and female vines, space them a few meters apart to allow room for growth and pollination. For container growing, use a large pot (at least 30 liters) with peat-free, ericaceous compost and good drainage.
Caring for Your Kiwi Plant
Watering
Kiwi plants need regular watering, especially during flowering and fruiting. The soil should be moist but never soggy. Mulching helps retain moisture and suppress weeds but keep mulch away from the base of the plant to prevent rot.
Feeding
Feed your kiwi vines with a balanced fertilizer in spring and a high-potash fertilizer weekly during summer to encourage flowering and fruiting. Organic compost or well-rotted manure applied annually also benefits growth.
Pruning
Pruning is essential for healthy growth and fruit production. In winter, cut back up to one-third of the oldest branches to a bud near the main stem to stimulate new growth. In summer, pinch back new shoots to keep the vine manageable and direct energy into fruiting.
Training the Vines
Train your kiwi vines along your support structure by tying stems gently as they grow. This helps keep the plant tidy and maximizes sun exposure for fruit development.
Harvesting Kiwi Fruit
Kiwi fruits typically mature between August and September but are best harvested when they are firm yet slightly yielding to gentle pressure. Seeds inside the fruit should be black, indicating ripeness.
If you pick them a bit early, kiwis will continue to ripen off the vine if stored at room temperature. Once ripe, they can be refrigerated to prolong freshness.
Troubleshooting Tips
– Root rot: Avoid waterlogged soil by ensuring excellent drainage.
– Lack of fruit: Check you have both male and female plants or a self-fertile variety.
– Pests: Use insect sprays if needed but opt for natural options to protect your garden ecosystem.
Growing kiwi takes patience, but the lush vines and delicious fruit are well worth the effort. With the right care, your kiwi vine can become a beautiful and fruitful addition to your garden.
