New Fen Globe Onion Sets (Heat Prepared)

  • Catalogue Code 1040-6000
  • Pack Contents: Approx. 75 Onion Sets

Usually ready for despatch a few weeks before other heat prepared sets (often from early/mid March).

New Fen Globe can be planted in early March, allowing the roots to get well established while there is still plenty of moisture in the soil, so helping to beat summer drought.

Because it benefits from a longer growing period, New Fen Globe also yields a heavier crop than most. Reliably produces heavy crops of big, but still mild-flavoured onions.

Individual onions can weigh up to 1lb and, with careful culture, will make excellent showbench specimens. Grown as a normal crop, each pack of approx 75 sets should produce 50lbs or more of top quality onions.

Ready to harvest in late summer/early autumn, giving time to dry the bulbs naturally before storing them. Kept in a cool, dry, airy place, stored bulbs will stay in good condition right through to the following May.

New Fen Globe Onion Sets (Heat Prepared) 1040-6000

Prevent and Supress onion white rot

White rot is a disease that affects bulb vegetables like onion and shallots. Once you’re onion crop’s got it, it’s impossible to cure as such and you’ll need to stop growing onions in the same spot for at least eight years. You’ll recognise it at harvest time by fluffy white mould with black speckles that grows around the base of the bulbs.

Have no fear there’s a great way you can prevent it getting to your onions in the first place!

Before planting your onions plant a crop of green manure called Caliente mustard. It’s a great organic means of creating a soil environment that’s uninviting to the disease.

Caliente mustard is a known as a bio-fumigant and once it’s chopped up and dug into the soil, it releases a natural gas that repels the pathogens that cause the rot along with many other soil diseases.

Just sow a pack from any time between March and October for a quick crop before your autumn-planting-crops or sow in November to overwinter for planting crops in spring. Just before it flowers, cut it down and dig well into the soil.

Caliente Mustard single packs can be purchased here.

Caliente Mustard double packs can be purchased here. 


Brilliant onions, great flavour store well.
