It is best to be cautious with planting seedlings. I distinctly remember waiting until the first of June to plant things outside only to have them killed off by frost on June 3rd! That was a crazy year in Ontario because snow fell, 3 feet of it, on the 24th of October. Shortest growing season I can remember.
Yes Canada can really have crazy weather. The last two years we have been getting a hard frost in mid August. It really does make it hard to garden. If I had more funds I would make two or three greenhouses and just do all my garden in there. I have plans so that the different plants can be in different buildings so they can have their needs provided for. Ah one day.
Keep that dream! Someday it will be a reality!
Thanks so much. I will.
Have a great day.
