Growing Exhibition Onions: Tips and Techniques for Producing 1200g Bulbs

Planting Onion Sets or Seeds

When it comes to planting exhibition onions, you have two options: using onion sets or sowing onion seeds. Both methods have their pros and cons, so it’s up to you to decide which one suits your needs and preferences best.

Planting Onion Sets

Onion sets are small, dormant onion bulbs that are grown the previous year and are ready to be planted. They offer a few advantages over onion seeds:

• Quicker to establish: Onion sets already have a head start and will establish themselves faster in the soil compared to seeds.
• Uniform size: Sets are usually of a similar size, which can result in more consistent growth and bulb development.
• Less prone to disease: Onion sets are less susceptible to certain diseases compared to seeds, providing an added level of protection.

Here are the steps to plant onion sets:

1. Prepare the soil: Onions prefer well-drained soil with plenty of organic matter. Remove any weeds and loosen the soil to a depth of at least 6 inches.
2. Plant the sets: Place the sets in the prepared soil, with the pointed end facing up. Space them about 4-6 inches apart in rows that are approximately 12 inches apart.
3. Cover and water: Gently cover the sets with soil, ensuring that the tips are still visible. Water the soil thoroughly to help the sets settle in.
4. Maintain: Keep the soil consistently moist, but not waterlogged. Remove any weeds that may compete with the onions for nutrients.

Sowing Onion Seeds

Sowing onion seeds is another method of growing exhibition onions. Here are some considerations when choosing to sow onion seeds:

• Greater variety: Seeds offer a wider range of onion varieties to choose from, allowing you to experiment with different flavors, sizes, and colors.
• Cost-effective: Seeds are generally more affordable than sets, especially if you plan on growing a large number of onions.
• Longer growing period: Onion seeds take longer to grow and establish compared to sets, so patience is required.

To sow onion seeds:

1. Start indoors (optional): If you live in a region with a short growing season, start the seeds indoors several weeks before the last frost date.
2. Prepare the soil: Choose a fertile, well-drained area and prepare the soil by removing weeds and adding organic matter.
3. Sow the seeds: Plant the seeds about 1/4 inch deep and space them 1 inch apart. Cover the seeds with soil and gently firm the soil surface.
4. Water and maintain: Keep the soil evenly moist during the germination period. Thin the seedlings to allow proper spacing as they grow.

Whether you choose onion sets or seeds, ensure that you provide your exhibition onions with the right growing conditions, including adequate sunlight, watering, and fertilization. With proper care and attention, you’ll be on your way to producing 1200g bulbs that will impress at any exhibition.

Providing Adequate Watering and Drainage

Watering is a crucial aspect of growing exhibition onions, as it directly affects the size and quality of the bulbs. Here are some tips to ensure adequate watering and drainage for your onions:

1. Consistent Moisture Levels

Onions need consistently moist soil throughout their growth cycle. Irrigate regularly to maintain a consistent level of moisture in the soil. Avoid overwatering or allowing the soil to dry out completely, as both can have negative effects on bulb development.

2. Deep and Infrequent Watering

When watering, aim to provide a deep soak to encourage root growth. Shallow watering can result in shallow root systems, which may lead to smaller bulbs. Frequent, light watering can also increase the risk of disease and pest problems. Instead, water deeply and less frequently to promote healthy root development.

3. Mulching

Applying a layer of organic mulch around the onion plants can help retain moisture in the soil and reduce evaporation. Mulching also helps to suppress weed growth, which can compete with the onions for water and nutrients.

4. Proper Drainage

Adequate drainage is crucial for the health of onion plants. Onions can be susceptible to root rot if left in waterlogged soil. To ensure proper drainage, plant onions in raised beds or mounds and amend the soil with organic matter to improve its structure. Avoid planting in areas with poor drainage.

5. Monitoring Soil Moisture

Regularly monitor the moisture levels in the soil by checking the depth at which it feels moist. This can be done by inserting a finger or a moisture meter into the soil. Adjust your watering schedule based on the moisture levels to prevent under or over-watering.

By providing adequate watering and drainage, you can help your exhibition onions reach their full potential and produce 1200g bulbs that are sure to impress.

Feeding and Fertilizing Onion Plants

Feeding and fertilizing onion plants is crucial to ensure healthy growth and the development of large bulbs. Here are some tips and techniques to help you properly feed and fertilize your onion plants.

Soil Preparation

Before planting onion sets or transplants, it is important to prepare the soil by incorporating organic matter, such as compost or well-rotted manure. This will provide essential nutrients and improve the soil’s structure and drainage.

Choosing the Right Fertilizer

Onion plants require a balanced fertilizer that contains nitrogen (N), phosphorus (P), and potassium (K). Look for fertilizers with an NPK ratio of around 10-10-10, or one that is specifically formulated for vegetables.

Alternatively, you can use organic fertilizers, such as fish emulsion or seaweed extract, which provide a slow-release of nutrients and promote soil health.

When to Fertilize

Onion plants should be fertilized at specific stages of their growth to maximize bulb development.

1. Pre-Planting: Apply a balanced fertilizer or compost before planting to provide a nutrient-rich environment for young onion plants.
2. Early Growth: After the onion plants have established themselves, apply a nitrogen-rich fertilizer to promote leaf growth. Be careful not to over-fertilize, as this can result in excessive foliage and small bulbs.
3. Bulb Development: As the onion plants start forming bulbs, switch to a low-nitrogen, high-phosphorus fertilizer to encourage bulb size and development.

Applying Fertilizer

When applying fertilizer, it is important to evenly distribute it around the onion plants without touching the foliage. This can be done by hand or by using a controlled-release fertilizer, such as granules or slow-release spikes.

Ensure that the fertilizer is watered in thoroughly after application to prevent burning the roots and to help the nutrients penetrate the soil.

Additional Tips

• Monitor the moisture levels of the soil and ensure that the onion plants receive adequate water, as this will help the plants absorb and utilize the nutrients from the fertilizer.
• Avoid using excessive amounts of fertilizer, as this can lead to leaching of nutrients and environmental pollution.
• If using organic fertilizers, follow the manufacturer’s instructions for application rates and frequency.
• Regularly check the pH level of the soil to ensure it is within the optimal range for onion plants (pH 6.0-7.5).

By following these feeding and fertilizing techniques, you can provide your onion plants with the necessary nutrients for robust growth and large, healthy bulbs.

Controlling Weeds and Pests

When growing exhibition onions, it is important to control weeds and pests to ensure the best quality and yield of your crop. Here are some tips and techniques to help you in this endeavor:

Weed Control

• Hand-pulling: Regularly inspect your onion beds and remove any weeds by hand. This is a tedious task but is effective in preventing weeds from competing with your onions for nutrients and water.
• Mulching: Apply a layer of organic mulch, such as straw, around your onion plants. This will help suppress weeds by blocking sunlight from reaching the soil and prevent weed seeds from germinating.
• Weed fabric: Consider using weed fabric or landscape fabric in your onion beds. This fabric allows water and nutrients to reach the onion roots while preventing weed growth.

Pest Control

• Aphids: Monitor your onion plants for aphid infestation. Aphids are small insects that suck the sap from plants, causing stunted growth and distorted leaves. Use insecticidal soap or a strong stream of water to control aphids.
• Onion maggots: These pests are the larvae of flies that lay their eggs near the base of onion plants. To prevent onion maggots, cover your onion beds with a floating row cover or apply a layer of diatomaceous earth around the base of your plants.
• Thrips: Thrips are tiny, slender insects that feed on onion leaves, causing silvering or bronzing of the foliage. Use insecticidal soap or neem oil to control thrips.
• Wireworms: Wireworms are the larval stage of click beetles and can cause severe damage to onion bulbs. Rotate your onion beds annually to reduce the risk of wireworm infestation. You can also use bait traps with pieces of raw potato or carrot to lure and control wireworms.

Organic Pest Control

If you prefer organic methods for pest control, consider the following:

• Neem oil: Neem oil is derived from the neem tree and is an effective organic insecticide. Dilute neem oil according to the instructions on the product label and spray it on your onion plants to control pests.
• Diatomaceous earth: Diatomaceous earth is a natural product that is composed of the fossilized remains of diatoms. Sprinkle diatomaceous earth around your onion plants to control insects. The sharp particles of diatomaceous earth damage the exoskeleton of insects, leading to dehydration and death.
• Natural predators: Encourage natural predators, such as ladybugs, lacewings, and predatory mites, in your garden. These beneficial insects feed on pests, helping to keep their populations in check.

By implementing these weed and pest control measures, you can protect your exhibition onion crop from weeds and harmful pests, ensuring a successful harvest of large and healthy bulbs.

Proper Onion Bulb Size and Thinning

One of the key factors in growing exhibition onions is achieving the proper bulb size. Here are some tips and techniques to help you achieve the desired size and quality:

1. Selecting the Right Onion Variety

Choosing the right onion variety is crucial in obtaining large exhibition-sized bulbs. Look for varieties that are known for their ability to produce large bulbs, such as ‘Ailsa Craig’ or ‘Kelsae’. These varieties have been bred specifically for exhibition purposes and have the potential to grow bulbs weighing 1200g or more.

2. Starting with High-Quality Onion Sets or Seeds

Starting with high-quality onion sets or seeds is essential for getting the best results. Look for sets or seeds that are large and firm, indicating good viability and potential for bulb development. Avoid sets or seeds that are soft, shriveled, or moldy.

3. Adequate Spacing and Thinning

Proper spacing and thinning are crucial factors in achieving the desired bulb size. Onions should be spaced at least 4-6 inches apart to allow enough room for bulb development. Additionally, thinning is necessary to ensure that each onion plant gets enough resources to produce a large bulb. Thin the seedlings or sets to one plant every 4-6 inches.

4. Providing Optimal Growing Conditions

To encourage bulb growth, provide optimal growing conditions for your onions. Onions prefer full sun, well-draining soil, and regular watering. Ensure that the soil is fertile and rich in organic matter by incorporating compost or well-rotted manure before planting. Use mulch to help conserve moisture and suppress weed growth.

5. Proper Fertilization

Fertilization is key to promoting bulb development. Onions are heavy feeders and require regular feeding. Use a balanced fertilizer with a higher ratio of phosphorus, which promotes root and bulb development. Apply the fertilizer according to the manufacturer’s instructions, being careful not to over-fertilize, as this can lead to excessive foliage growth at the expense of bulb development.

Following these tips and techniques for proper onion bulb size and thinning will increase your chances of growing exhibition-sized onions weighing 1200g or more. Remember to monitor your plants regularly and make adjustments to their care as needed to ensure optimal growth and bulb development.
