The Benefits of Companion Plants for Your Garden


Companion planting is the practice of planting two or more plants together for mutual benefit.  Not all companion planting charts are the same. You may find one that conflicts with another as companion planting is not completely explained by science so use any chart as a guide.

Here are some benefits of Companion Planting Vegetables:

  1. Shelter – larger plants protect others from wind or too much sun.
  2. Support – Some vegetables can be used as physical supports for others. As an example, pole beans planted with corn use the corn as a trellis.
  3. Beneficial Insects – attracting beneficial insects such as bees help spread pollen.
  4. Soil Improvement – some vegetable plants improve soil conditions for other plants. For example, members of the legume family (beans etc.) draw nitrogen from the atmosphere and add it to the soil around them.
  5. Decoy Plants – there are plants that emit odors that aid in masking the odors of insect-desirable vegetable plants.

Here is a good chart as a reference to what plants make good and bad companions for others and the source used for the information below.

Some examples are:

Cabbage – rosemary repels cabbage flies.  Beets, dill, onions, potato, marigolds, nastriums are some of the good companions. Keep cabbage away from peppers, tomatoes and strawberries.

Lettuce – Mint repels slugs which feed on lettuce.  Beans, beets, carrots, peas, radishes, marigolds are some of the good companions. Keep parsley away from lettuce.

Spinach – beans and peas provide natural shade for spinach that does not like too much sun.  Lettuce, melons, tomatoes, nasturtium, cabbage, cauliflower and strawberries are other good companions.
