Vegetable crop yields and the number of vegetable plants to grow for each person in your household will help you estimate the space needed for a home vegetable garden.
Crop yield estimates and consumption predictions are largely base on experience. Keeping a food log and garden record can help you hone your vegetable garden needs and make for smarter planning.
Vegetable crop yields will vary according to garden conditions and variety planted. Weather and growing conditions can change from year to year, and these changes can affect yield.
