Whether you want to expand your gardening knowledge or simply enjoy the satisfaction of nurturing a plant, starting kiwi from seed is a fascinating and fulfilling endeavor. In this article on how to grow kiwi from seed, we will discuss the steps involved in germinating and caring for kiwi plants, as well as some tips for successful cultivation.

Why Start From Seed?

There are a few reasons why starting kiwi from seed can be a rewarding experience. Firstly, it allows you to have complete control over the growth and development of your plant, as you will be involved in every step of the process. Additionally, starting from seed can often be more cost-effective than purchasing an already established plant.

Needed Materials

• Kiwi Seeds (Can Be Purchased Online or Saved From Fresh Kiwi Fruit)
• Potting Soil or Seed-starting Mix
• Small Pots or Containers With Drainage Holes
• Water Source
• Sunlight or Grow Lights

5 Simple Steps on How to Grow Kiwi From Seed

Step 1: Prepare the Seeds

• If using seeds from a fresh kiwi fruit, rinse them under running water and gently remove any remaining flesh.
• If purchasing kiwi seeds online, make sure to follow the instructions on the packaging for proper preparation.
• Soak the seeds in water for 24 hours before planting. This will help soften the seed coat and increase germination rates.

Step 2: Choose a Pot or Container

• Kiwi plants have deep roots, so choose a pot or container that is at least 8 inches deep and has drainage holes.
• You can also use biodegradable pots, such as peat pots, that can be planted directly into the ground when the plant is ready.
• Make sure the pot or container is large enough to accommodate the mature size of a kiwi plant, which can reach up to 30 feet in length.

Step 3: Prepare Potting Mix

• Kiwi plants prefer well-draining soil with a pH level between 5.5 and 7.0.
• You can purchase pre-made potting mix specifically for fruit trees or make your own by mixing equal parts peat moss, compost, and perlite or vermiculite.
• Avoid using regular garden soil as it may compact too much and hinder root growth.
• Fill the bottom of your pot with a layer of broken clay pots or stones to ensure proper drainage.

Step 4: Planting

• Gently remove the kiwi seedling from its nursery pot, being careful not to damage the roots.
• Place the plant in the prepared potting mix, making sure the top of the root ball is level with the soil surface.
• Backfill with more potting mix and lightly press down to eliminate any air pockets.
• Water thoroughly until water begins to drain out of the bottom of the pot.

Step 5: Caring for Your Kiwi Plant

• Place your potted kiwi plant in a sunny location with at least 6 hours of sunlight per day.
• Water regularly, keeping the soil moist but not waterlogged. Use your finger to check the moisture level in the soil before watering.
• Fertilize once a month during the growing season with a balanced fertilizer.
• Prune your kiwi plant in late winter or early spring to maintain its shape and promote new growth. Remove any dead or damaged branches.
• Keep an eye out for pests and diseases. Common pests for kiwi plants include aphids, spider mites, and scale insects. If you notice any signs of infestation, treat the plant with an appropriate insecticide.
• In colder climates, protect your potted kiwi plant by bringing it indoors during the winter months.
• As your kiwi plant grows, it may need to be repotted into a larger pot every 2-3 years.
• Harvest your kiwis when they are firm but slightly soft to the touch. They will continue to ripen after being picked.

Additional Tips for Growing Kiwi Plants

• Ensure your kiwi plants are well-watered, especially during dry periods, but avoid overwatering as it can lead to root rot. 
• Mulching around the base of the plants can help retain moisture and reduce weed competition. 
• Prune your kiwi plants regularly to promote healthy growth and improve fruit production. Focus on removing dead or overcrowded branches. 
• Support your kiwi vines with a sturdy trellis or arbor to allow them to grow upward and receive adequate sunlight. 
• Monitor for diseases such as fungal infections and treat them promptly to prevent damage to your plants. 
• Fertilize during the growing season with a balanced fertilizer to encourage strong growth and abundant fruiting. 

By following these additional tips, you can create the optimal conditions for your kiwi plants to thrive and produce a bountiful harvest.

Common Problems and Solutions

Growing kiwi plants can sometimes pose challenges, but most issues can be managed with proper care and attention. Here are some common problems and their solutions:

Yellowing Leaves

This could be a sign of nutrient deficiency, most commonly iron chlorosis. Ensure your soil has a slightly acidic pH and consider adding an iron supplement or chelate to the soil.

Poor Fruit Production

Lack of fruit can result from inadequate pollination. Make sure to plant both male and female vines to facilitate proper pollination, and attract pollinators like bees by planting flowering plants nearby.

Pests

Aphids, spider mites, and scale insects can damage kiwi plants by feeding on the leaves and stems. Use insecticidal soap or neem oil to manage infestations effectively.

Overwatering

Kiwi vines are sensitive to waterlogged soil, which can lead to root rot. Plant them in well-draining soil and ensure you do not overwater.

Cold Damage

While some kiwi varieties are more cold-hardy, unexpected frost can damage young shoots. Use frost covers or mulch around the base of the plant to protect it during colder periods.

By identifying these issues early and addressing them promptly, you can help your kiwi plants stay healthy and productive year-round.

Do You Need to Use Professionals?

Whether or not you need professional assistance for growing and maintaining kiwi plants largely depends on your level of experience and the scale of cultivation. For home gardeners with a few vines, most tasks like planting, pruning, and pest management can typically be handled with a little research and preparation.

However, if you are managing a large-scale kiwi orchard or facing persistent issues, such as severe pest infestations or soil health concerns, consulting a professional can be invaluable. Specialists in horticulture or agricultural services can provide tailored advice, advanced treatments, and resources to help your kiwi plants thrive efficiently and sustainably.

How Much Will It Cost?

The cost of growing kiwi plants can vary widely depending on factors such as the scale of your operation, the quality of materials you use, and the specific needs of your plants. At a small scale, expenses might include the purchase of seeds or saplings, soil amendments, trellising materials, and basic tools, which can range from a few hundred to a couple of thousand dollars.

For larger-scale orchards, costs increase significantly, involving advanced irrigation systems, professional consultations, pest management solutions, and potential labor expenses. It’s important to budget for ongoing costs as well, including routine maintenance, fertilizers, and any unforeseen issues. By creating a detailed financial plan, you can better manage expenses and ensure your kiwi-growing endeavor stays both productive and cost-effective.
