Our scapes have just started to emerge, and although we are always later than you guys, my friend checked the farm journal and we are later than last year, they had scapes in the CSA share in the second week of July and it's not happening yet this time.
Most of my garlic is Music, which I grew from bulbils that formed on some scapes in my vegetable bin the season before last... I spaced them an inch apart in a big tray, and they produced the good sized rounds that I planted last fall... can't believe they are big enough to make scapes, and garlic, after just two years.
It's true they're not all full size, but I'm happy to see any, as I've read it could take as long as 4 years.
The one Leningrad I got from the farm is also putting on the scape, but Chesnok Red are not.. they are nice big plants though.
