Companion Planting Your Vegetable Gardens

The benefits of companion planting your vegetable gardens is endless. If planned right you can boost your harvest and overall crop health significantly. Companion planting is great for your plants, soil and can even be good for wildlife if done correctly.

You can keep away pests, welcome in pollinators, improve overall crop tastes and even encourage a more bountiful growth just by “pairing” up certain vegetables. By that, I mean your vegetable gardens so particular plants are nearby to one another.

Make sure to do your research, however, because some pairs can actually do more harm than good. Be sure to plant those pesky pairs a distance from one another.

Here is a list to help you in getting started with companion planting your vegetable gardens…
