FAQs
When is the best time to sow Onion 'Red Baron' F1 seeds?
For the largest bulbs and best colour, sow seeds under glass from late winter to early spring. Direct sowing outdoors is also possible from early spring, or by using heat-treated sets.
What type of soil do these onions prefer?
They prefer well-drained soil with a neutral to alkaline pH. Avoid planting in ground that has been recently heavily manured.
How long do 'Red Baron' F1 onions store for?
This variety is known for excellent keeping quality and can store well for several months after harvest if dried properly and stored in suitable conditions.
Can I grow these onions in containers?
While possible, onions generally perform best when grown in open ground where they have ample space for bulb development. If using containers, ensure they are deep enough and provide good drainage.
What is the difference between sowing seeds and using sets?
Sowing seeds offers more variety choice and is generally more economical, but requires more time and care. Sets are small, partially grown bulbs that are easier and quicker to plant, offering a more reliable crop for beginners but with less variety choice.
How tall do the plants grow?
The plants typically reach a height of around 450 mm (approximately 18 inches).
Troubleshooting
Seeds not germinating
Ensure seeds are fresh, sown at the correct depth, and kept consistently moist and warm during the germination period.
Bulbs are small or not developing well
Check soil fertility, ensure adequate sunlight, and consistent watering. Thinning seedlings appropriately is crucial for bulb size.
Onions rotting in storage
Ensure bulbs are fully dried before storing. Store in a cool, dry, well-ventilated location and remove any onions showing signs of rot.
Yellowing leaves before bulb formation
This can be a sign of nutrient deficiency or water stress. Ensure adequate feeding and consistent moisture levels.

Setup, Compatibility & Care
Sowing: For best results, sow seeds thinly in trays of compost under glass in late winter or early spring. Transplant seedlings into the open ground when they are large enough to handle, usually after the risk of frost has passed. Alternatively, heat-treated sets can be planted directly into the ground from early spring.
Soil: 'Red Baron' F1 onions prefer well-drained soil with a pH that is neutral to alkaline. Avoid recently manured ground.
Location: Choose a sunny spot in the garden.
Care: Keep the area weed-free, especially when the bulbs are small. Water during dry spells to ensure good bulb development. Support the plants if they become top-heavy.
Harvesting: Harvest when the foliage begins to yellow and fall over. Dry the bulbs thoroughly in a warm, dry place before storing.
