The guide says Sept - Oct planting - if that isn't your Spring then it won't grow.

How often do we water garlic?

Put your finger in the soil if it is dry below 1 inch, add water.

What about growing elephant garlic in zine 9b? Is it the same as regular garlic?

It's best to plant hardneck garlic in zone 6B from the middle to late October or even early November. The key is you want it to be cold, consistently below 45°, at least every night time. The first freezing encounter triggers garlic to start producing roots and that would determine how healthy and large the plants grow. Keep in mind freezing above ground may not equal freezing below ground. If you plant it in too warm a time, like early October, it may stunt the growth. It may even rot the garlic if it's wet too long. You may be able to accelerate the process by keeping in the refrigerator for a few weeks I'm not even know people who have kept it in the freezer for a few days or longer hopefully triggering root growth. I haven't tried that so I don't know.

I have success in planting from October 1 up until Early Dec….harvesting late May through July. Nice large bulbs in Zone 7b, getting close to 8a.

Hi, thank you for your comment. What type of garlic do you grow? Can you send me some advise on how you grow it including fertilizers that you use etc? I am growing in zone 8a. Thank you so much, Miriam.

Hey Miriam I'm in zone 8A and I grow Purple Glazer, Italian Mountain Red and Inchelium Red in my raised garden beds. I plant anytime from 10/15 until Halloween. I havent used fertilizer in the past so I cant comment on that. However if you live in SC, Clemson Coop Esxtension has a great site for information on growing all sorts of veggies. I usually start harvesting late May till Mid June (my neighbor said to harvest when half of the leaves have turned yellow/brown. Hope this helps and good luck with growing garlic for next year

We would like to plant garlic for next summer. We live in the Seattle area.....so we are going to be headed into a lot of rainy weather for the next few months. When should we plant my cloves to get big multi clove bulbs and when would we harvest them? We plan on using large containers....should they be moved into a place with a little weather protection during the heaviest rain? We planted in February last year and got tiny tiny bulbs..... The same question for leeks if you know about those too..... Thanks very much! Annemarie
