Onion Sets - F1 Centurion

RHS Award of Garden Merit winner.

There is no doubt in our minds why the Onion Sets - F1 Centurion is a winner of the RHS Award of Garden Merit. It is simply superb. Producing heavy crops that mature early, this first rate onion is very strong growing. The Onion Sets - F1 Centurion will fare well in the indifferent British summers and produce beautiful onions all the same. The even skin colour and uniform globe shaped bulbs create stunning onions, perfect as a show bench subject. Not to mention they taste absolutely great! They’ll certainly enhance any meal you add them to.

Growing Information

Growing Information

Onions like a sunny, sheltered site in well-drained soil. Plant onions sets 10cm apart in rows 30cm apart from October to mid-April (dependant on variety). Gently push the sets into soft, well-worked soil so that the tip is just showing, and firm the soil around them. 

Water if the weather is dry and give an occasional feed with a general liquid fertiliser. A light feed of high potassium fertiliser in June will help ripen the bulbs ready for storage. Stop watering and feeding once your onions have begun to gain some colour on the top, and remove any mulch or soil to expose the bulb to the sun.

Onions can be harvested when the foliage turns yellow and starts to topple over. Leave for two to three weeks and then carefully lift with a garden fork. If you wish to store onions they must be firm, disease-free and then dried for two to three weeks, either laid out in the sun or in a shed if the weather is wet.
