Once I realized what was really happening with the alliums, I gave the Camelot shallots (grown from seed) a good once over as well. These were cured and braided back in late August. Surprisingly, they didn’t have any holes in them at all. Having done a bit of research on onion maggots, I found that they prefer yellow onions to red, so this may be why they show no damage and why the Rossa di Milano onions had less damage than the yellow varieties.

· Total # of bulbs – 110
· Largest bulb - 262 grams (9.2 oz)
|Rossa di Milano|
· Total # of bulbs – 119
· Largest bulb - 258 grams (9.1 oz)
· Total # of bulbs – 42
· Average bulb size - 298 grams (10.5 oz)
· Largest bulb - 756 grams (1.67 lbs)!!
There were no runts here – all of the Ailsa Craig’s were “normal”, if you could call ¾ pound+ onions normal!
· Total # of bulbs - 289
That is a LOT of onions. Too many maybe? I do use them practically every day so there is the possibility that they may in fact not be enough…we shall see.
Firstly, I will be transplanting the onion seedlings sooner - I transplanted them late this year as the new bed wasn’t ready yet. I'm hoping this will give me either larger onions or an earlier harvest.
I may also adjust the spacing on the Copra’s (I used 4” this year) to see if I get bigger onions or fewer runts. I did a mini-experiment on the Rossa di Milano’s, using 5” spacing for some & the recommended 4” spacing on others, and didn’t really see too much of a difference between them (although I didn't exactly weight/measure them), so I think I will stick with 4” for next year. The Ailsa Craig’s did fantastic with their 6” spacing - no tweaking is necessary there.
And, of course, the most important change - netting the beds. The beds will be covered as soon as the transplants go into the ground next spring in an effort to avoid those darn onion maggots.
