Surviving the winter

This is my first year of square foot gardening, actually any gardening. I started the first part of June so was a bit late for summer and didn't get very good yields. But I did learn a lot. I planted carrots, beets and broccoli in August and most of them are still doing well. I thought this cold snap of 7 degrees would do them in but they are still kicking.

I could have gone out and pulled everything but I wanted to see what they would do over the winter in Georgia. I did not realize carrots would keep on living like they have. The beets aren't doing much, (the leaves haven't grown very big) but I'm hoping they will take off in the spring. Do you think they will?

I've read that carrots will seed the second year so when should I actually pull them? I'm going to plant more this spring so should I just pick them right before I plant the new seeds?

Oh, and it looks like I lost my biggest broccoli plant to the freeze. It looks like the stalk split. But the smaller ones are still alive. Will they produce in the spring as well?

Hi there
With Regards to carrots, I actually do not even begin harvesting them until winter, and I am in a much colder climate than yours. After the ground has gotten cold they get sweeter and being left in the garden seems to be the best way to preserve them
I also leave a few carrots to go to seed the next year.... I have yet to get much from this process, but this next year I should get a lot of "volunteer" carrots as the flower that the carrot sent out was HUGE (BTW the bees absolutely LOVE the carrot flowers)
Not sure about the rest of your questions because my climate is very different

I didn't realize the carrots get sweeter as it gets colder. Thanks for sharing that tidbit. I'm really curious about the carrot flower so may just leave some for seed.

 I have lots of colors of carrots I ordered last year and am dying to try them. I ordered them from Amazon and they shipped from Hong Kong. Nothing on Amazon said these seeds came from Hong Kong. I found that odd. I had almost forgotten about the order they took so long to arrive.

I just realized I didn't exactly post this under the proper topic. Oops.
