The autumn sown onion sets are in stock now (and cheaper than almost anywhere else) so it’s the perfect time to pick them up and get an early crop on the go. Now that we’re into September, it’s an ideal time to get them in the ground so that you can enjoy a crop in June next year, a month or two before the spring sown ones. It’s an ideal way of keeping successional crops, much like getting in broad beans which you’ll need be starting in October and November, before the ground starts to get too cold.
The white ones in the shop at the moment are Shakespeare, I’m not sure of the red ones at the moment as I forgot to take a note of the name at the weekend, I’ll update this when I find out.
How to plant.
This is probably teaching many to suck eggs, but for everyone else, here is a snippet on how to get them going.
Plant onion sets in rows in any firm, well drained soil in full sun. Prepare the planting area several weeks in advance by incorporating some well rotted garden compost to improve drainage and soil fertility. Avoid planting onions on freshly manured soil. On particularly wet ground, try growing onion sets in raised beds. When growing onions from sets, plant the bulbs so that the tip of bulb is just protruding through the soil surface. Leave a space of 10cm (4″) between each bulb, and 30cm (12″) between each row.
