When first planning to grow your garden, there are a few things you need to consider: How many members you have in your family, how much your family likes the vegetables you eat and how well you can store the excess vegetable crops you may have, are all factors that can influence the size of a family vegetable garden.
The most important thing to consider when deciding how big your family garden should be, is how many people in your family you need to feed. Adults and teens, will of course, eat more vegetables from the garden then children, infants and toddlers. But, if you know the number of people you need to feed in your family, you will have a starting point for how much of any vegetable you need to plant in your family garden.
Additionally, when planning for your garden consider if you will be planning to serve only fresh vegetables, or if you will be preserving some to last through fall and winter.
