Heat Treated Onion Sets - It's frustrating when your beautifully forming onions decide it's time to develop seed and send up a flower stalk. Heat treating is a process that we carry out on your behalf to prevent this happening. So whilst they are a little more expensive, you can be more confident of harvesting onions you can be proud of!
Hardiness:-6 to -10 degrees
Beds & Borders:True
Prefers Full Sun:True
Heat treatment starts in November depending on the size of the bulb. During the heat treatment, the onion sets are gradually heated up over 12 days from the 3-5°C storage temperature to 30-32°C and, depending on size, are kept at this temperature for 30-60 days (during which time they are heated up to 32-35°C for 10 days) and then gradually cooled to 10-14°C for planting in April/May. So whilst they are a little more expensive, you can be more confident of harvesting onions you can be proud of!
Ideal for beds and borders, raised beds. Prefers full sun.
