Hi DDH, Looks like your last frost date is May 17th. http://www.almanac.com/garden/frostcanada.php From this site: Pole Bean growing info "Germination temperature: 70 F [21 C] to 80 F [26 C] - Germination is slow and poor when soil temperatures are below 60 F [15 C]." Newt
I can't remember where I read it... someone suggested starting the beans in between moist paper towels for a day or two before planting out. -Ana http://www.gardennut.com
