yes square foot fan here in Florida I am afraid I will not be much help to you as you are in the frozen tundra of south canukistan. I planted lettuce and spinach last weekend along with radishes and some other stuff that likes cooler weather all my last lettuce having bolted in June. Our climate here is much different than yours sq ft style works well so one does not have to enrich large expanses of sugar sand. Put the herbs where you can get them easily to cook with even a window box is good.
Well, I could be harvesting lettuce now if I had gotten it in at the end of Aug. or beginning of Sept. But, that would be the last hurrah around here. It’s getting colder and rainier by the day. We’ve had 2 light frosts already and a lot of rain. I saw “flurries” two weeks ago on a Sat., but no real snow in sight yet. It’s only a matter of time, however.
