You still have time to plant garlic this fall. I am late in getting a small patch of Mennonite in for a trial I am experimenting with this year. I will be planting it next week when i have time. As long as the ground is not frozen you can plant. Just be sure to cover with mulch as soon as the ground does freeze.
The types of garlic i have left for ordering are
Puslinch (small quantity left)
German (small quantity left)
Russian (lots since we didn't plant it all)
