Long-day onions are best for northern areas. They need 14-16 hours of daylight. Plant them in early spring for a summer harvest.

Preparing Your Garden Bed
Planting fall onions starts with a well-prepared garden bed. A good garden bed ensures your onions grow healthy and strong. Follow these steps for the best results.
Soil Preparation
First, test your soil’s pH level. Onions need slightly acidic soil with a pH of 6.0 to 6.8. You can buy a soil test kit at a garden store. If your soil is too acidic, add lime. If it’s too alkaline, add sulfur.
Next, remove all weeds and debris from your garden bed. Weeds compete with onions for nutrients. Clear them out to give your onions the best start.
Then, add organic matter like compost or aged manure. This improves soil structure and adds nutrients. Spread a 2-inch layer over the soil and mix it in well.
Finally, ensure proper drainage. Onions do not like waterlogged soil. If needed, create raised beds to improve drainage.
Ideal Garden Location
Choose a spot that gets full sun. Onions need at least 6 hours of sunlight each day. More sun helps them grow bigger and healthier.
Consider the wind. Strong winds can damage onion tops. Plant in a sheltered area or use windbreaks if your garden is windy.
Think about crop rotation. Avoid planting onions where you grew garlic or other alliums last year. Rotate crops to prevent soil diseases.
Check for good drainage. The garden bed should not be in a low area where water collects. Onions need well-draining soil to thrive.
By preparing your garden bed properly, you set the stage for a bountiful onion harvest.
Planting Techniques
Planting fall onions is simple with the right techniques. These techniques ensure healthy growth. Let’s dive into the details.
Seed Vs. Set Planting
There are two main methods to plant onions: seeds and sets.
- Seeds: Seeds take longer to grow. They need more care and attention. Start them indoors for best results.
- Sets: Sets are small onion bulbs. They are easier for beginners. They grow faster and need less care.
Choose the method that suits your gardening style. Both have their benefits and challenges.
Optimal Planting Depth
Planting depth is crucial for onion growth. Follow these simple steps:
- Dig a trench 1 inch deep for seeds.
- Place seeds in the trench, 1 inch apart.
- Cover lightly with soil.
- For sets, dig holes 1 inch deep.
- Place each set in a hole, pointy end up.
- Space sets 4 inches apart.
Proper depth ensures strong roots and healthy onions. Water well after planting.

Watering And Fertilizing
Ensuring your fall onions receive proper watering and fertilizing is essential for a bountiful harvest. Onions need consistent moisture and the right nutrients to grow strong and healthy. Follow this guide to keep your onions thriving throughout the fall season.
Watering Schedule
Water your onions regularly to keep the soil moist. Onions prefer a steady supply of water. A good rule is to water them deeply once a week.
- Check the soil moisture with your finger.
- If the soil is dry 1 inch down, it’s time to water.
- Water early in the morning or late in the afternoon.
Avoid watering in the evening to prevent fungal diseases. If it rains, you might not need to water that week.
Best Fertilizers For Onions
Onions need fertilizers rich in nitrogen. Nitrogen helps onions grow big and strong. Use a balanced fertilizer at planting time.
| Fertilizer Type | Application Time |
|---|---|
| Compost | Mix into soil before planting |
| Fish Emulsion | Apply every 2 weeks during growing season |
| Bone Meal | Sprinkle in planting hole |
Side-dress with a nitrogen-rich fertilizer every 4 weeks. This keeps your onions growing steadily.
Follow these steps, and your fall onions will thrive. Happy gardening!
Pest And Disease Control
To grow healthy fall onions, you need to control pests and diseases. This guide will help you understand common onion pests and how to prevent onion diseases. Follow these simple steps to ensure your onions thrive.
Common Onion Pests
Onions can attract several pests. Below are some common pests and how to manage them:
- Onion Maggots: These small, white larvae can eat your onion roots. Use row covers to prevent them from laying eggs.
- Thrips: These tiny insects suck sap from onion leaves, causing them to wilt. Spray neem oil to keep them away.
- Aphids: These pests suck the juice from onion plants. Introduce ladybugs to your garden, as they eat aphids.
Preventing Onion Diseases
Diseases can also harm your onion crop. Follow these tips to prevent common onion diseases:
- Rotate Crops: Do not plant onions in the same spot every year. Crop rotation helps prevent soil-borne diseases.
- Watering: Water the onions at the base, not the leaves. Wet leaves can lead to fungal infections.
- Proper Spacing: Plant onions with enough space between them. Good airflow reduces the risk of disease.
- Remove Infected Plants: If a plant shows signs of disease, remove it. This prevents the disease from spreading.
Use these pest and disease control tips to grow strong, healthy onions this fall. Happy gardening!
Harvesting Your Onions
Harvesting onions at the right time ensures they are tasty and long-lasting. This section will guide you through identifying mature onions and the proper techniques for harvesting them.
Signs Of Maturity
Before harvesting, check for signs that your onions are ready:
- Leaves turn yellow and fall over.
- Bulbs reach the desired size.
- Necks become soft and pliable.
Inspect your onions closely. Mature onions have dry, papery skins. If they still have green leaves, wait a bit longer.
Proper Harvesting Techniques
Follow these steps for a successful harvest:
- Choose a dry, sunny day.
- Use a garden fork to loosen the soil.
- Gently pull onions from the base of the leaves.
- Shake off excess soil.
Lay the onions in a single layer in the sun to dry. This process is called curing. Curing helps onions develop a protective skin.
After curing, trim the leaves and roots. Store the onions in a cool, dry place. A mesh bag or wooden crate works well for storage.
By following these steps, you can enjoy fresh, homegrown onions all year round!
Storing And Preserving Onions
Storing and preserving onions is crucial for a successful harvest. Proper techniques ensure your onions stay fresh and flavorful for months. This guide will walk you through the steps of curing onions and the best storage practices.
Curing Onions
Curing onions helps extend their shelf life. It involves drying them to reduce moisture. Follow these steps:
- Harvest onions and remove excess soil.
- Place onions in a dry, ventilated area.
- Allow onions to cure for two weeks.
- Check for soft spots or mold.
Best Storage Practices
After curing, store onions properly to maintain freshness. Here are some tips:
- Keep onions in a cool, dry place.
- Use mesh bags or baskets for ventilation.
- Store away from potatoes to avoid spoilage.
- Check onions regularly for signs of decay.
Following these methods will help you enjoy your onions for longer periods.

Expert Tips For Success
When planting fall onions, success depends on several critical factors. Follow these expert tips to ensure your onions grow healthy and strong. By focusing on companion planting and seasonal care tips, you will maximize your harvest.
Companion Planting
Companion planting involves growing onions with other plants that help them thrive. This practice can boost growth and repel pests. Here are some excellent companions for fall onions:
- Carrots: Carrots help break up the soil, allowing onions to grow better.
- Lettuce: Lettuce provides ground cover, reducing weeds around onions.
- Strawberries: Strawberries and onions protect each other from pests.
Avoid planting onions near beans or peas. These plants can stunt onion growth.
Seasonal Care Tips
Proper seasonal care ensures your fall onions develop fully. Follow these steps to keep your onions healthy throughout the season:
- Watering: Water onions regularly, but do not overwater. Aim for moist, not soggy soil.
- Mulching: Use mulch to retain soil moisture and control weeds.
- Fertilizing: Apply a balanced fertilizer every few weeks. This boosts growth.
- Weeding: Remove weeds promptly. Weeds compete with onions for nutrients.
Consider these tips to ensure a bountiful onion harvest. Happy planting!
