I have never chilled mine and they do okay. I don't know the type as I have as I started with grocery store bulbs, but I have read that soft neck varieties do better in warm climates.

Probably make no difference. The thing is to use mature aged bulbs. Fresh new bulbs may not be as good as bulbs that have been out of the ground for a few months.

Can I plant garlic bulbs in pots (that will remain outside throughout winter) in zone 5b?

If you can grow it in the ground you can grow it in a pot usually.

I just moved to Naples Florida. I am looking for hard neck and soft neck varieties that would grow here. I am thinking that planting on December 21 and harvesting June 21 maybe a good start. It doesn't get frosty here, but perhaps vernalizing the bulbs in the refrigerator for 40 days may work. Appreciate any thoughts.

Garlic grows GREAT here in Florida, but only the soft neck varieties, & you must give them 8 weeks artificial winter in a refrigerator prior to planting. Preferably one without ripening fruit as they put off gasses that can hurt your garlic whilst chilling.

David, I also live in Zone 10A but in California (hot and dry, average 10 inches of rain per year), and please IGNORE the Aussie who thinks we do not check our Zone 10A recommendations. I have been container gardening here for a couple years and am still learning, with notable mistakes being not knowing correct planting/harvesting times (I now use this website over anything on a seed package), overcrowding, and overwatering. I have successfully grown garlic in Zone 10A, from store bought garlic cloves that were sprouting tiny green shoots, and they produced but the heads and cloves were only about half the size as the original store-bought, which might be caused by the climate, or more likely from be the mistakes I was making trying to grow new things like crowding, overwatering, and not knowing when to plant or harvest. Anyway, give growing garlic a try and my best advice is to avoid overwatering. I had a lot of cloves rot instead of growing and I think it was because of overwatering. After doing more research I'm trying to grow garlic again by planting some in NOV, and some in DEC, and really monitoring the watering. Even though my garlic was half sized, it still tastes great, so I would rather have half sized garlic I can grow myself than not growing garlic.

I planted Australian Purple Garlic. Think it's the wrong variety. Grew ok..I think? But has been fairly static for a while. Confusing reading on garlic. Some say plant march and harvest in September.7 months. Most others say it's a 9 month crop. Any advice please. Tia John.
