Onion Bridger F1 Seeds
Onion Bridger F1 is an outstanding overwintering hybrid developed for gardeners seeking dependable early harvests, exceptional bulb quality and impressive exhibition potential. Comparable in performance to the highly regarded Tasco F1, Bridger produces beautifully shaped onions with rich golden-brown skins that resist splitting and remain clean and attractive throughout the growing season. Its excellent winter hardiness and reliable performance make it an ideal choice for UK gardeners, allotment holders and exhibition growers alike.
The vigorous plants establish quickly during autumn, developing a strong root system before winter arrives. As temperatures rise in spring, Bridger resumes active growth, producing medium to large semi-globe bulbs that mature earlier than many traditional onion varieties. The firm, well-protected skins provide excellent presentation on the show bench while also helping the bulbs cure successfully after harvest. The crisp white flesh has a mild, sweet flavour, making Bridger equally suitable for salads, sandwiches, roasting, soups and everyday cooking. Whether grown for competitive exhibition or simply for a reliable early onion crop, this versatile hybrid consistently delivers excellent results.
Each packet from Fosters Seeds contains approximately 120 seeds, usually more, providing excellent value for home gardeners and exhibitors alike. The variety performs exceptionally well under cover for producing clean, unblemished exhibition onions, but also grows successfully outdoors in fertile, well-drained soil.

Sowing & Propagation
For the best overwintered crop, sow seeds in modules or small pots during August or September. Grow young plants until they are well established before planting under cover in October.
Alternatively, sow in January under glass at around 18°C. Transplant seedlings outdoors when they reach the three to four leaf stage, spacing plants approximately 15 cm (6 inches) apart each way in fertile, well-prepared soil.
Growing On
Choose a sunny, sheltered site with deep, fertile, moisture-retentive soil that has been enriched with well-rotted compost or manure. Keep plants well watered during dry periods and maintain a weed-free growing area to reduce competition.
Feed with a balanced fertiliser during early growth, switching to a higher potash feed as bulbs begin to swell. Bridger’s excellent bolting tolerance and strong skin quality make it particularly dependable for overwinter cultivation. Growers aiming for exhibition-quality bulbs often prefer to cultivate the crop under cover, where cleaner, blemish-free onions can be produced.
Harvesting
Harvest from June to July when the foliage naturally begins to yellow and bend over. Lift bulbs carefully on a dry day and allow them to cure thoroughly in a cool, well-ventilated location.
For optimum storage and skin finish, cure the onions in complete darkness with good air circulation until the necks have fully dried. Proper curing enhances both keeping quality and exhibition appearance.
