Yep.
Many started Victory gardens to supplement their/relatives/friends food staples.
I was just coming home from kindergarden when I saw daddy in the side yard with a man, and a horse with a moldboard plow. We ended up with potatoes on the right side of the house, corn in front and and a mixed garden toward the left. After the war we dropped the potatoes and corn in front, but kept the big garden and grew about 50 varieties of various vegetables. Had the Victory Garden for 10 years, grew about 1/4th of our total food. Canned food for winter. Learned to work while neighbor children played. Learned entrepreneurship when pop let me sell surplus and keep the money. Never had a cavity until I went to college dorm food. Got 6 the first year there. This was 2 miles from New York City.
