Please Note

These seeds should ideally be sown this season. All our packets have ‘Sow by Date’ guidance on them, this is the date the seeds should be sown in order to achieve the highest rate of germination. You will still see the same high-quality plants if sowing in seasons after the ‘Sow by Date’ but may see a reduction in germination rate

  • Royal Horticultural Society Award of Garden Merit
  • Store well

Grow onion Rumba; a top-performing main crop variety that’s ideal for growing in the UK. Rumba produces high yields of large, uniform, round onions with a sweet flavour, making it ideal for eating raw in salads as well as cooking.

Heat-treated over a period of time before arriving to you, your sets are less prone to bolting and going to seed, which in turn affects the quality of the bulbs.

Good thick skin and quality flesh makes this a good variety for long-term storing.

Pre-Rooted Sets

Grow bigger, stronger onions ready to harvest earlier in the season with our pre-rooted onion sets! Our innovative NEW format is ideal for Spring planting and for gardeners with small plots.

Do you know why birds like to pull up your freshly planted onions, it isn't just to see your angry face! No, it is because they are after the earthworms that in turn are attracted to microbes present in the immediate area around the rooting called the Rhizosphere. Microbes feast on the proteins, sugars and dead cells created from the plants roots. However, as these are pre-rooted the birds will find them harder to pull up and should leave them alone. The microbes in turn, provide the plants with essential nutrients and so the cycle continues.

To give you a head start on the growing season, we’ve pre-rooted onion sets into plug trays, with each cell containing 1 set. Unlike normal sets, which take several weeks to start growing after being planted, these pre-rooted plugs are already rooted and growing when you receive them, ready to plant out. They’ll establish quickly, producing bigger, stronger plants earlier than traditionally planted sets, with less risk of birds or animals pulling out the sets.

Our pre-rooted onion sets are great for gardeners with small plots who only have space for a few plants and don’t want to waste a big bag of sets. There’s no more waiting to see whether all your sets will sprout – you can already see them growing! And if you missed your chance to plant sets earlier in Autumn, these pre-rooted sets are already ahead and no time is lost.

Plant out as you would normal sets, gently puck the base of each cell to ease the rooted plug out of the packaging. This can be planted directly into the ground without any root disturbance.
