I live and garden in Quebec, Canada which, like you, is zone 3, but our first frost-free day of the year is not until June. I would love to follow some of your planting guides, but it would be helpful for me to know when your last frost typically occurs so I can adjust my plantings accordingly. Thanks so much for sharing your energy and love for gardening with us! /Becky Torretti

Actually the date when our last-frost-nights are over are June the 6th I think. But most often it's not that late. 2019 we hade a late frost in the end of May. Most often I plant both vegetables and flowers in the garden already in May, well prepared to protect them with a fabric if cold nights should appear. /Sara
