I don't have much
experience with corn. I'm in zone 3b/4a but I wonder if Canadian and US zones are similar?
Last avg. frost on May 19, first avg. frost September 26. Vegetable gardens are usually planted on the 15th of June.
Wet and cold Springs, dry short Summers, cool and wet Falls.
I chose Ashworth's Rat Selected from
Hope Seeds. It's said to be 65-75 days.
I removed the top soil, loosened with my broadfork and added maybe 3 inches of marine
compost. I was running out so that was thinner than planned.
I sowed on June 22, saw sprouts on the 27th (five days) and harvested on September 10 so 80 days if I'm not mistaken.
Cobs were small but very good!
