Zone 3 growers typically have frost and cold weather already starting before October. So going into October there isn't much that can be planted going into winter. That being said, there is still time to plant garlic. Planting garlic in October will give it an early start come spring. Below is a list of items that can be planted in zone 3 in October.
Red Toch is a certified, beautiful garlic with stripes of red and pink! The Red Toch is also know as “Tochliavri” in the small Republic of Georgia village from which it hails. This garlic variety is another vigorous member of the Artichoke family and produces 12 to 18 cloves in a typical bulb. The widely celebrated flavor of the Red Toch has been described by famed garlic symposium organizer Darrell Merrell as “not too mild, not too hot”, and having “a mellow spicy tang with a fragrant aroma.”
