I live in Missouri. We have awful summers! Very hot and humid, especially July and August. I just don't want to wait too long or plant too early and end up with nothing (potato wise).It may depend on your area you may be able to plant them after the last frost if your summers are very cool but here we plant them with the peas about 8 weeks before the last frost. You do have to protect potatoes from frost if they’re above ground when a frost comes though.

I wasn’t happy with my potatoes last year but I’m giving them another try this year, I’m growing in bags. Gurneys won’t even ship to me until 2/5 which is our average last frost date.
Anyway, sorry for the tangent, I’m just enjoying the heck out of having ducks. I was looking at the garlic earlier and I think there was 100% germination so I’ll be ordering a larger amount of seed for this year and dedicating a larger area to it in fall.
