This is my first year gardening. I've recently become a stay at home mom and decided I'd like to get into gardening, both to have something to do in my off time as well as to try and help save money by growing my own produce rather than having to buy it. The issue I'm trying to figure out currently is how much of a garden do I need to provide produce for a family of 3 (soon to be 4)? I would like to freeze fresh fruits and vegetables to be able to have them when I need them as well as keep some fresh stuff on hand. I think I'm going to concentrate on: Tomatoes (Cherry and Regular Size), Carrots, Lettuce, Spinach, Potatoes, Peas, and Herbs. I'd love to have corn, melon etc..but I don't think I have the space for them. So what would you suggest? How many plants to make a difference in our grocery bill?
