Having a garden usually means an abundance of vegetables (zucchini anyone?). And while it’s true that nothing in natural systems really goes to waste i.e. the veggies that you don’t harvest go to flower, attract beneficial insects, and ultimately get recycled back into the soil, a little bit of attention paid to how much you grow, might minimize any wasted time, effort, and water.
The question of how much you should plant, however, is a difficult one to answer. Like so many things in gardening, the answer is, “It depends.” It depends on what your family likes to eat, whether you just want summer vegetables or want enough for the entire year, how much space you have, how good your soil is and how much of a yield you can expect. In other words, there is no easy answer. However, here are some recommendations of where to get started.
In contrast, vegetables like carrots, parsnips, onions, winter squash, and potatoes are fairly inexpensive to buy from local growers. Here in Montana, for example, we can actually get local organic storage crops for our farmers, well into the winter. In addition, these crops typically take up a lot of space. If you have a limited growing area, I would plant less of these and more of the higher value veggies that I mentioned.
Now having said that “it depends,” the list below is a good starting point. These are recommendations for a family of four to five people for a year’s worth of vegetables. You would of course adjust this based on what I talked about previously. It also assumes that you’ll be spending part of the harvest season preserving your veggies either through freezing, canning, or dehydrating. So use this as a guide, take good notes this season, and start customizing it to your family’s needs.
