|My biggest onions, July 2017|
Several garden onions are a pretty decent size now; some are approaching store-bought size. Some are not. I sowed the seeds in January in a tray on my kitchen windowsill. I planted them out in February (I think? Or was it March?) in clusters of two to five onions. As space is limited, growing in clusters rather than rows means I get more onion per square meter (or about half a meter in this case). The bulbs are bigger on average this year than previously; last year I planted out onion sets separately, not in clusters.
They have also been getting the diluted contents of our wee bucket (yes, you read that right) two or three times a week. I don't know if it's made them bigger/stronger but I've read that all the onion family like a lot of nitrogen. When I can be bothered to walk all the way to the end of the Misc bed, I'll give the leeks a dose too.
But the onions are still growing and I'm not prepared to harvest them until they reach their maximum size. We may be going without onions for a few weeks. I guess I could always pull up a few shallots; having planted them from grocery store bulbs I'm not quite so invested in their success--I really pampered those onions to get them to where they are today!
