Leave that second set. That happend to me last year when I made the fatal mistake of planting them with my broad beans (to discourge black fly)
Left some of the "spring onion" sized mini cloves, and they came up first this year before the winter sown ones, and I have started cropping them a couple of weeks ago, really brilliant bulbs.
THis year I did the same thing as last and sowed next to my broad beans garlic. Then I read its one of the big no-no's. Didn't know why.....until now.
The extra nitrogen in the soil from the beans makes the garlic bolt. I planted loads of garlic this year as I have the lottie, some next to beans some not. All the ones next to beans have tried to flower, and this means that there will be smaller bulbs, but hopefully an extra set . I may leave these for next year and see if I get loads!.

I've just read that if they "bolt" is also to do with if they are a soft neck,semi hard neck or hard neck type. The harder the neck the more chance they will put on a flower. But wait, in America these are a sort after and are known as Scrapes, and used in stir fries and salads.
They sell for quiet some money....
Wished I hadn't composed mine now
