SNOWBALL Onion Sets – Premium White Onion Sets for Autumn & Overwinter Planting

EXTRA LARGE SETS 21/24mm

Grow strong, reliable crops with our Snowball Onion Sets, the perfect choice for gardeners looking for onions to plant in autumn for an early harvest the following summer. These top-quality sets are specially selected for overwintering, producing firm, round white onions with a mild flavour and excellent keeping qualities.

Ideal for UK gardens and allotments, Snowball onion sets establish quickly in cooler weather, making them a popular choice for autumn planting. Once planted in late summer or autumn, they overwinter in the soil and give you a healthy, early crop the next year—weeks earlier than spring-planted onions.

✔️ Perfect for autumn & winter planting – Hardy onion sets that thrive through the colder months
✔️ Reliable overwintering variety – Strong disease resistance and excellent winter hardiness
✔️ Early harvests – Enjoy large, uniform white onions earlier than spring-planted types
✔️ Easy to grow – Low maintenance and suitable for all experience levels
✔️ Great storage onions – Snowball onions keep well once harvested, ensuring a long-lasting kitchen supply

Planting & Growing Tips:

Plant sets in well-drained soil from September to November.

Space 10cm apart in rows, with 25–30cm between rows.

Keep weed-free and water during dry spells.

Harvest from June onwards for crisp, white bulbs perfect for salads, cooking, and storing.

Whether you’re looking for onion sets for autumn planting, reliable overwintering onions, or simply want an easy, rewarding crop for your vegetable patch, Snowball Onion Sets are a proven choice trusted by gardeners year after year.
