Seed storage help!

(Question)

Hi there
I am growing a garden in Zone 10 – Barrie, Ontario and just have a question that im looking to seek an answer as soon as possible.
I have some vegetable seeds i just planted last weekend that i forgot to bring inside over the winter time such as beets, spinach, bush beans, cherry tomatoes, zucchini, as well as a variety of herbs, and im wondering if there is a chance they will still germinate or if i should just buy new seeds all together.
Any help and advice would be greatly appreciated
Thanks so much

As long as your seeds were dry, they are probably ok. Freezing dried seeds is a way of storing them. However, in the presence of moisture, a trigger to begin the plant’s growth, without other growing conditions, it can cause the vegetable seed to age more quickly and, over time, the seed will fail to germinate. In addition, water in undried seeds expands when it freezes and can damage the cell wall and render the seeds unusable. You might want to try sprouting some of the seeds in baggies with a damp paper towel so you can check if they germinate.

Good luck!

P.S. I am not quite sure what zone you are referring to in your question, I assume it is not the Canadian Plant Hardiness as Barry is a zone 5a?
