I've plant onion and have about 8 inches of growth.

Garlic should be started in the fall as garlic needs a longer cool cycle.

I have annual onions planted (and will be planting more) and perennial onions are beautiful right now. I also grew some leeks this year, we've been enjoying them quite a bit.
I plant garlic on Halloween and harvest it at the end of May.

I have planted my garlics last October. Now they are about 18" tall, with 6 to 8 leaves. I should be able to harvest them in May. I have planted some ontions(plants and sets) the are up about 6". Today at Buford HWY Farmers maket I saw some nice pearl onions, red and yellow.Perfect size for planting. I will try to find a place to squeez those in.I will plant them real colose to gether and will thin them as green onions, leaving every third one to mature.
Onions are easy to plant ang grow but tricky. Some are short day, some long day and some intermediate. So, if you plant the wrong kind, you may not get good crop. I think here in ATL/GA area we should plant short day onions and plant them very early. I know the sets that I just bougt from Farmers Market may not do well. First, it is a bit late, and second, I don't know what variety they are. But I figure, I can just use them as green Onions.

Kewl...Thanks....I guess I am already late for both the plants. Its still too cold for me to venture out in my slopey yard.

I've had the 'same' garlic growing for years. I dig it up and take one clove and replant it. This year I have some garlic that I'm going to plant near it. These are in my rose bed believe it or not.

Gotta come and see your garden someday buford...I really would like that a lot! I am close to ya.
