We had a Victory Garden as well. WIth all of the current landscape being torn up to place houses literaly on top of one another, I do not think that Victory Gardens would be common place like they were should they be needed. Sad!
Our city has set aside an area for Community Gardening. I think cities are doing more of this as people wish to grow their own-well some do.
I can garden in pots, but don’t.
I guess the open spaces around newer developments would be turned into community gardens in an emergency. Having a garden was always common in the small towns where I grew up..My husband and I had one at our last home. There was a space out of sight behind the garage we dug up...a tough go in that black clay soil N of Dallas. The plum tomatoes spoiled me forever. My DIL ate them like grapes.
