Tips for Growing Onion Sets

Planting time may differ between onion sets, though they are generally best planted in early autumn or spring in a sunny, well-drained spot. With some watering when the weather is dry, feeding with nitrogen-rich fertiliser such as our onion, garlic, and shallot fertiliser, weeding, and the removal of any flower stems, your onion sets will grow vigorously. When the plant’s foliage turns yellow and topples over, your onion sets will be ready for harvesting.

You can choose from our heat-treated onion sets for even more simple growing. These onions are kept at warm temperatures for several months, which makes them easier and faster to grow, with the added benefits of being much less likely to bolt and higher yields. Our heat-treated onion set collection includes two of our best heat-treated varieties with bold, delicious flavours.
