Last year I managed to grow an onion that was over 3lb. This was grown outside in the raised bed. This I was very pleased with, but I wished that I tried to grow one in the greenhouse to see if it would grow even bigger. Protected from winds I thought I could grow a four pounder!

I was very kindly given onion seeds for my birthday last year and sowed them in the middle of November 2016. These came on very well and did not suffer any damage from frosts in the greenhouse. I was given a second batch of seed at Christmas, and planted the second batch on New Years day 2017. I was hoping that the earlier sowing would benefit from a longer growing season.

The experiment has not worked out as I thought. The two onions that I have in the greenhouse have gone-over so I have had to lift them. The New Year sowing weighed in at 1lb 5oz, while the November 2016 sowing was a little heavier at 1lb 11oz. Not the result I had expected.

The outdoor onions are still growing and are visibly larger than the greenhouse onions. I will lift and weigh them when they are ready, and I’m sure I have at least one three pounder.
