I might be wrong but I vaguely recall that hardneck is usually better for north because they are more cold-hardy.
Falling over tops I think is for onions, though garlic can fall over too -- usually from too much moisture when they're ready to be harvested.
I harvested these (marked by the thin bamboo sticks) two days ago to make room for more sweet potatoes.
In the photo, it doesn't look 2/3 browned because I pull off the browned leaves and papery skin attached to them when cleaning off the encrusted muck (which, as I've said before, is probably earthworm casting mucus).
Yeah to the hardneck. True confessions time: I don't like to grow root crops. I can't see what they're doing, so I lose half the pleasure I take in gardening. I planted these just to see what happens. I don't know what kind they are, but someone said that is what is sold in the supermarkets, and someone else said softneck don't develop scapes, so I'm betting they are softneck.
I was darned surprised when they came up this spring. So, I probably won't experiment with hardneck. I've now grown garlic. Been there; done that. I'm a seasoned garlic grower and can add that to my resume
I'd like to see them through to the end, keep a few, and give the rest to my neighbors.
It would be nice, though, if they made it through to fall, when I need garlic. Unfortunately, I fear my garlic experiment may be drawing to a close. They're not brown yet, not like yours, but I'm betting they're not far off. The very tip of one is a bit crispy. This could be because I didn't water them, too. They pretty much do their own thing and are easy to ignore. Mine have been on autopilot since the first tip erupted from the soil in March. (Which, I will admit, was pretty nifty to see.)
I finally gave them a serious soaking a few days ago. I should know by next week whether that brown tip presaged maturity or neglect
