Can You Plant Seeds In Fall In ND?

The key to successful winter gardening is knowing the average date of the
      first killing frost in your region. You then plant your winter crops early enough to let them reach
      their full maturity before that killing frost.
When should I plant my seeds/When is my last frost date?
Not all seeds should be planted at the same time. All of our seeds come
with recommended planting times and, most of these recommendations are
based on your "last frost date". Some crops, like cabbage, broccoli and
lettuce can tolerate a light frost while other, like peas and spinach
are very cold tolerant and can be planted whenever the ground can be
worked. Squash, cucumber and Basil we die if they are planted too early
and exposed to frost. Tomatoes, peppers and eggplants, even when
started indoors, will die if they are transported outdoors prior to the
last frost planting.

Knowing and planning around the predicted last frost date in your
region is critical to the survival of your home garden. The best source
for you to research this information is the National Climatic Data Center.
