FAQs
How many seeds are in a packet?
Each packet contains approximately 350 'Fasto' F1 hybrid seeds.
Can I save seeds from my 'Fasto' F1 onions for next year?
No, 'Fasto' F1 is a hybrid variety. Saving seeds will not produce plants true to the parent type; it's best to purchase new seeds each season.
When is the best time to sow 'Fasto' F1 seeds?
You can sow seeds indoors from late winter to early spring, or directly outdoors from early spring after the risk of hard frost has passed.
How long does it take for 'Fasto' F1 onions to mature?
'Fasto' F1 is an early maturing variety, typically ready for harvest in mid-summer, depending on sowing time and growing conditions.
What conditions do 'Fasto' F1 onions prefer for storage?
For optimal storage of up to six months, keep cured onions in a cool (around 4-10°C), dry, dark, and well-ventilated place.
Can I grow 'Fasto' F1 in containers?
Yes, 'Fasto' F1 onions grow well in containers, provided the container is deep enough and offers good drainage.
Troubleshooting
Seeds not germinating
Ensure seeds are fresh, planted at the correct depth, and soil is kept consistently moist but not waterlogged. Check soil temperature is adequate for germination.
Bulbs are small or misshapen
Ensure adequate spacing between plants, consistent watering, and sufficient soil nutrients. Poor soil fertility or overcrowding can lead to small bulbs.
Onions bolting (producing a flower stalk)
Bolting is often caused by stress, such as cold temperatures followed by warmth, or irregular watering. While 'Fasto' F1 is generally resistant, extreme conditions can trigger it. Remove bolted plants as they tend to have poorer flavour and storage.
Poor storage life
Ensure bulbs are fully cured before storage. Store in a cool, dry, dark, and well-ventilated location. Remove any damaged or diseased bulbs before storing.

Setup, Compatibility & Care
Sowing: Sow seeds indoors or directly outdoors after the last frost. Prepare a well-drained soil enriched with compost. For direct sowing, plant seeds about 1-2 cm deep and 10-15 cm apart. If starting indoors, use seed trays and transplant seedlings when they are large enough to handle, typically 8-10 cm tall, spacing them similarly.
Compatibility: 'Fasto' F1 is compatible with most standard garden soil types. It grows well in vegetable beds, borders, and containers. Ensure good air circulation around the plants.
Care: Keep the soil consistently moist, especially during dry periods. Weed regularly to prevent competition. Once the tops begin to yellow and fall over, this indicates the bulbs are maturing. Allow them to dry in the ground for a few days if conditions permit, before lifting.
Curing and Storage: After harvesting, cure the bulbs by leaving them in a warm, dry, well-ventilated area for 1-2 weeks until the skins are dry and the necks are sealed. Store cured onions in a cool, dry, dark place, ideally in mesh bags or crates to allow for air circulation. Check periodically and remove any onions showing signs of spoilage.
