I shop for annuals once a year, usually at the end of May or beginning of June – like most other people who live in New England. If we shop too early, the plants have to wait somewhere until all chance of frost has passed. OR, they can go into the cold ground and take their chances. All plants cost too much to risk dying in a freeze, and I can’t be bothered to go out and cover my plants. I just wait and try to get them into the ground at the correct time. And slowly but surely I am learning how to garden in the north.
