Onion 'F1 Guardsman' is a recently introduced variety which combines a lack of pungency with minimal bulbing, so the stems stay straight and also have a sweeter flavour. This very distinct and innovative variety has been recently been recognised as the most widely grown salad onion.
Guardsman feature an unusually strong root system, they have strong, upright, dark blue-green leaves. The 55cm (22in) plants are vigorous and high yielding and mature just ten weeks from sowing.
Perfect for the kitchen or the show bench, they will be producing salad-ready scallions in July, less than two months from a spring sowing
Guardsman is resistant against Botrytis, it is not only very suitable for the summer cropping period, but also ideal for autumn crops when disease can be a particular problem.
Onion 'F1 Guardsman' has been awarded the RHS Award of Garden Merit. (AGM).
An ideal position would be an open, sunny site with good drainage which has been dug and manured in the previous autumn. Do not plant or sow on freshly manured bed.
Avoid planting in an area where the previous crop was of the onion family. Many exhibitors grow their show onions in a permanent bed in order to build up fertility, but in the kitchen plot it is a much better idea to change the site annually.
Onions prefers a neutral to slightly alkaline soil so lime if the soil is acid. Apply a general fertiliser if needed and rake the surface when the soil is reasonably dry. Tread over the area and then rake again to produce a fine, even tilth.
Sowing: Sow in autumn or sow successionally from late winter to late summer.
In cold areas and for exhibition bulbs sow under glass in January,
Sow thinly 12mm (½in) deep in either narrow or broad drills allowing 15 to 23cm (6 to 9in) between drills. No thinning is necessary.
The seed germinates over a wide range of temperatures and is faster at higher temperatures. Sow every 3 weeks for continuous crops.
Keep well watered for best quality crops, especially during spells of dry weather. It will stand well for long periods if kept well watered. Hoe carefully or weed by hand – dense weed growth will seriously affect yield.
Harvesting: 60 days
Harvest as required from May to October, later sowings may remain through to December if the weather remains mild. Best when used immediately though they will keep in the fridge for a few days.
Spring onions can be used for so much more than just adding to your Peking Duck pancakes. When raw or very lightly cooked they impart a wonderfully vibrant yet mild flavour where normal onions would be overpowering. Make some champ by folding chopped spring onions into creamy mashed potatoes - add some grated cheddar if you like - and marvel at how such a simple dish can taste so fantastic. Or combine with ginger to form the soul of a number of classic Chinese and Japanese dishes.
Trim off the root and about a centimetre from the green tops. The bulb area can be eaten raw or cooked but the tops are best when chopped and added to a dish just before serving.
Store in the fridge for up to four days.
For years onions have been used as one of the oldest medicines for their anti-bacterial, antiseptic and anti-asthmatic properties. They have also shown to lower blood pressure and cholesterol levels.

Avoid following onions, shallots, garlic or chives.
Beet, carrot, celery, parsley and tomato.
Alfalfa, beans, peas - Onions inhibit the growth of legumes.
Eaten and cultivated since prehistoric times, onions were mentioned in first dynasty of ancient Egypt, circa 3200 BC, and have appeared in tomb paintings, inscriptions and documents from that time on. Some paintings depict onions heaped onto banquet tables, both the robust bulb onions as well as scallions.
The spring onion is believed to have originated in the Far East. Chives and spring onion are recorded in Chinese history from 2000 BC.
They were grown in Ancient Egypt, and eventually arrived in Rome and became known as the word onion from the Latin word Unio , which means 'large pearl'. In Middle English, it became unyon, as time passed the word developed into onion.
