This award-winning onion matures early even in less-than-great summers, producing a heavy crop of round bulbs with golden skins, crisp flesh and top-quality flavour. A holder of the prestigious RHS Award of Garden Merit, Onion ‘Centurion’ is easy to grow and stores well for a long period.

How you will receive your plants:

Selected by our team of experts and sent from our nursery, you will receive your onion sets in a breathable net bag. This keeps them together in a pack that is nice and airy – perfect to keep them healthy while in transit.

Can’t plant straight away?

Keep your onion sets in a cool, dark, and dry place and preferably hanging on a hook so that air can get to the bulbs at all angles. Ideally, you should aim to plant them within a week of receiving them, but if this is not possible, store them in a cool, dark place until you are ready to plant them.

Planting tips and hints:

A couple of weeks before planting, dig over the soil with a shovel to clear weeds. Rake in a general purpose fertiliser.

To plant your sets, push the sets into the soil with the pointed end upwards. Leave 5-10cm between sets. Cover the area with horticultural fleece to protect the young plants from birds.

Water regularly in dry periods, and weed regularly. Stop watering once the leaves start to yellow.

Harvest bulbs once the leaves have turned yellow and flopped over. Use a fork to carefully lift the bulbs.
