Someone said recently, maybe here, that spring (last frost) seems to come later and the first frost in fall comes later. The records (Fargo) show the first frost in fall is quite a bit later than 20 or 30 years ago. We had 32 degrees on May 20 of this year, colder in some areas. 6 days later we broke a record at 96. For gardening I think you would want to work around the typical frost dates for both spring and fall. I have been planting tomatoes (WI 55, 75 day) later and have had good results. Will put in my transplants this weekend, my latest tomato transplant date. Last year I had to rely on volunteer tomatoes as my transplants were a bust. They were likely just coming up in the middle of June. We had an early frost last fall, September 7, I believe. It did not kill the tomatoes (they produced) but there was frost on the leaves, it did kill the cucumbers a bit farther away from the trees. It was cold as the dew point was very high and the grass was covered in ice. This is where you need to think about Brix and the higher nutrient levels in plants as being kind of an antifreeze.
We may have a shorter growing season in the northern US but we also have some very long daylengths in summer. Garden with this in mind. You can do a lot in a short time with nearly 16 hours of daylight.
