Red onion ‘Karmen’ is renowned for the exceptionally sweet flavour of its crisp white flesh, delicious eaten raw in salads or cooked. Each layer of the onion is edged in light crimson, so it looks as good as it tastes! This popular red onion stores well and is a valuable addition to any kitchen garden.

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.

How To Grow

Prepare your soil: Onions, Shallots, and Garlic prefer an open, sunny site and light, free-draining soil. If you have heavy soil, dig in a generous amount of grit and organic matter into the planting area to aid drainage. Avoid planting them in very heavy or freshly manured soil. Onions are sensitive to acidity, so if you have acidic soil add some Garden Lime to the area well before planting or use our Concentrated Slow-Release Onion, Garlic & Shallot Feed Granules when planting.

Planting: Both Autumn and Spring varieties can be planted straight out into your pre-prepared soil. Loosen soil and dig in some of our Concentrated Slow-Release Feed Granules to add essential nutrients for optimal growth.

Onion & Shallot Sets: Plant Onion and Shallot sets (pointed end upwards) with the tips of the sets showing at the soil surface. 

Onions: These should be spaced 5-10cm (2-4in) apart with 25-30cm (10in to 1ft) between rows. 

Shallots: Should be spaced 15-20cm (6-8in) with 30-45cm (1ft to 18in) between rows. 

Garlic: The Bulbs should be separated into individual cloves and planted pointed end up, so that the tip of each clove is 2cm (1/2in) below the soil surface. Leave 15cm (6in) between individual cloves and 30cm (12in) between the rows. We also recommend covering garlic bulbs in Horticultural Fleece to protect emerging shoots from hungry birds!

 

Guide To Plant Sizes

We have hand planted these sets/cloves into the cells to start the growing process off. These are now all rooting nicely and many will have the green shoots emerging from the top of the set/cloves. Don’t worry if some aren’t showing yet, they will. As soon as you can, take them out of the packaging and give them a good water. If you cant plant them straight away, put them in the garden somewhere out of direct sunlight and strong winds, keep them moist until they are ready to be planted. In every cell there will be 1 set/clove, once you remove the plug from the tray, just ease these apart, be careful not to break too many roots. But they will re-produce a lot more roots once planted.
