Onions are a dependable, long‑lasting crop that reward patience with generous yields. They’re perfect for gardeners who enjoy growing staples that store well.
From soups to salads, onions are the backbone of countless dishes. By growing your own, you can enjoy crisp, juicy onions to use whenever you want or keep them to store over the winter.
Choose from:
Classic round bulbs for general use.
Slightly elongated onions that slice neatly.
Compact, early‑maturing varieties, perfect for smaller growing areas.
Red‑skinned onions, great for salads and grilling.
Onions prefer a sunny, open site with well‑drained soil. Prepare the ground by raking it level and removing weeds. Plant sets or sow seeds from early spring.
Onions grow best in open beds, in well-draining soil. Space sets or seedlings evenly so bulbs have room to expand.
If you don’t have space in beds, you can have a go at growing onions in containers; opt for compact varieties, choose a deep trough or pot and use free‑draining compost.
Water regularly in dry weather, especially early in the season. Reduce watering as bulbs mature to prevent rot.
A balanced fertiliser in early growth may be a benefit but avoid overfeeding. With onions, too much nitrogen leads to leafy growth rather than good bulbs.
Remove any flower stalks to keep energy in the bulb.
Plant sets with the tips just above the soil.
Keep the area weed‑free. Onions aren’t keen on competition!
Water during dry spells but avoid overwatering.
Stop watering once bulbs begin to swell.
Plant sets or sow seeds from early spring.
Harvest when the tops flop over and begin to dry. Lift bulbs and keep them in a warm, airy place, which will help long storage.
