We always had a big veggie garden to go with our flowerbeds. Mom was still growing veggies up until she broke her hip at 87 and couldn't live by herself anymore.
We live in FL, so no root cellars here, lol. However, we canned some every year. We also gave away a lot of fresh food, the neighbor kids would come over with sacks for us to fill with veggies during the summer and for oranges in the winter.
We tried a larger garden in the yard this year, but the ground wasn't good and was killing the plants so we just went with a container garden of a variety of heirloom tomatoes and assorted hot peppers . Now we know the issue, we just have to rent a rototiller and add lots of mulch and black cow. If that still doesn't work, we will do a raised garden with potting soil and that will absolutely do the job if necessary, but really hope it's not needed.
We've also planted a fig tree, but no fruit yet and are looking for a good pecan tree to plant. Guess some of mom's country upbringing got into my bones as well.
