I just received 8 baby strawberry plants from GRIN. I was expecting these months ago, before the summer heat set in. I am on the border between zone 4&5. We are still having 90 degree days and the frost date is 9/30. We have an average winter low of -15. Can I plant these babies outside this year? I can cover them with a cold frame and then mulch them like crazy. If not, what is the best way to overwinter them? I'm thinking that I should root them in buckets and when the cold weather comes, store them in the basement, which gets in the 40 degree range. If I do this, should I let them dry out or keep them wet? How about a heating pad under them and/or flourescent lights over? I also got blueberry seeds. Do these need a cold cycle to break dormancy? Thanks a lot.
