I didn't know there were any guidelines to front yard gardening, but I guess it makes sense. I have put a few vegetable pots in the front yard. A house down the street from me has a rock garden in the front and it slopes downward facing south. I noticed that they've grown pumpkins and squash etc, in amongst their flowers.^^^
Last year, I started my basement grow near the end of march. This year, I started earlier. Whether it's a good idea remains to be see. Half of my grow belongs to a next door neighbour in his 80s. We're Mutt and Jeff. He, a former market gardener from Bassano, and me, new to the game, a researcher.
I'm glad you enjoyed the front yard vegetable garden in Drumondville that I posted. The City of Calgary promotes this, subject to certain guidlines.
Success to all of us in this 2018 growing season.
I usually start the seeds around mid-March, but was so busy this year, I never got to it until the end of March.
