White Onion Seeds – Heirloom Onion Variety Vegetables
White Onion Seeds – Heirloom Onion Variety Vegetables
Premium Quality White Onion Seeds
Our White Onion Seeds produce large, mild-flavored onions that are perfect for eating raw. These White Onion Seeds have a light-brown skin and white flesh, making them a great addition to any vegetable garden. As a long-day onion variety, they thrive in northern regions where daylight hours are longer.
This heirloom onion variety is a cold-hardy onion that withstands cooler temperatures. However, while it grows well in cold climates, it does not store well for long periods. This makes it an excellent choice for fresh use rather than long-term storage.
Our non-GMO onion seeds are carefully selected and tested to meet the highest germination standards. They are also open-pollinated onions, ensuring strong and natural plant growth without genetic modifications.
Why Choose Our White Onion Seeds?
Non-GMO and Open-Pollinated
Our onion seeds are 100% non-GMO and open-pollinated. This means they are free from any genetic modifications and can naturally reproduce. With heirloom onion seeds, you get the advantage of saving and replanting seeds for future harvests.
High Germination Rate
We regularly test our high germination seeds to ensure a strong and healthy start to your growing season. This guarantees that you get the best results when planting.
Cold Hardy and Northern Region Adapted
These northern onion seeds are specifically suited for regions with longer daylight hours. As a cold hardy onion, it can withstand low temperatures and still develop well. If you live in a northern climate, this variety will perform best in your garden.
Mild and Sweet Onion Flavor
This mild onion variety is perfect for fresh eating, salads, and sandwiches. Unlike stronger onions, its gentle flavor makes it enjoyable without overpowering your meals. If you prefer a sweet onion variety, this is an excellent choice.
Eco-Friendly Packaging
We pack our organic onion seeds in resealable packets made from recycled materials. The packets are printed with vegetable-based ink, making them an environmentally friendly choice. We do not use plastic ziploc bags, ensuring sustainability in every order.
Growing White Onion Seeds
When to Plant
As a long-day onion, this variety needs at least 14-16 hours of daylight to form bulbs. The best time to plant is in early spring, as soon as the soil can be worked. In northern onion growing zones, start seeds indoors 8-10 weeks before the last frost.
How to Plant
- Start Indoors: For the best results, sow seeds in trays ¼ inch deep. Keep them in a warm area with plenty of light.
- Transplant: Once seedlings are 4-6 inches tall, transplant them into the garden. Space them 4-6 inches apart in rows.
- Direct Seeding: If planting directly in the garden, wait until the soil reaches at least 50°F. Sow seeds ½ inch deep in well-draining soil.
Soil and Sun Requirements
- Sunlight: Needs full sun for at least 14 hours daily.
- Soil: Prefers well-draining, nutrient-rich soil with a pH of 6.0-7.0.
- Watering: Keep soil moist but not waterlogged. Avoid overwatering, which can cause bulb rot.
Fertilization and Care
Use organic fertilizers high in nitrogen to promote leaf growth. Once the bulbs start forming, reduce nitrogen and switch to a phosphorus-rich fertilizer. Keep weeds under control, as they can compete for nutrients.
Harvesting and Storage
When to Harvest
Your vegetable garden onions will be ready for harvest when the tops begin to yellow and fall over. This usually happens 100-120 days after planting.
How to Harvest
- Pull Gently: Loosen the soil around the bulbs and pull them up carefully.
- Cure the Onions: Lay onions in a dry, well-ventilated space for two weeks. This helps toughen the outer skins.
- Use Fresh or Store: Since this variety is not ideal for long-term storage, it is best used fresh or within a few weeks.
Common Growing Challenges
Bolting
Inconsistent temperatures may cause premature flowering, known as bolting. To prevent this, ensure onions are planted early enough to mature before summer heat arrives.
Pests and Diseases
- Onion maggots: Use row covers to protect young plants.
- Fungal diseases: Avoid overhead watering and ensure proper spacing for air circulation.
Tips for Best Results
- Rotate onion crops yearly to prevent disease buildup.
- Mulch around plants to retain moisture and reduce weeds.
- Avoid planting near beans or peas, as they can hinder onion growth.
