Companion Planting – 60+ Plants and How to Use Them

The concept of companion planting goes back centuries. In nature, diverse ecosystems of plants live together, supporting and benefiting each other.

You hardly ever see an entire field of one plant in nature.

What is Companion Planting?

Companion planting is the practice of planting certain non-crop plants next to your crop plants for a number of benefits:

  1. Attract beneficial insects
  2. Attract pollinators
  3. Repel pests
  4. Fixing nutrients back into the soil
  5. Providing ground cover or support

While it may seem counter-intuitive to the beginner gardener, we actually want to attract certain insects into our garden.

In addition to pollination, beneficial insects such as lady bugs and praying mantises because they eat the pest insects like aphids.

Some companion plants do an especially good job of attracting pollinators with their brightly colored and fragrant flowers.

We plant these around our vegetables with the notion that pollinators are lazy, and while they’re already there for the cosmos, they’ll stay around and pollinate our squash.

Other companion plants emit a strong odor that pests detest.

Garlic, for example, repels slugs and aphids – which is great if we plant them next to our veggies who have a known weakness for aphids.

Plants such as beans, for example, fix nutrients back into the soil, making them available for neighboring plants.

Other plants may absorb nutrients, but make it readily available when they are composted or tilled back into the soil. For more, check out my post on cover crops.

Plants that can be used as ground covering provide a lot of added benefits. Using them as a mulch provides the soil coverage, helping it retain water and prevent runoff during a storm.

They also provide shelter and protection for some beneficial insects such as beetles and spiders.

In addition to the 5 benefits listed above, most can be used a culinary or medicinal herbs, or are vegetable crops themselves! I love anything that serves two, or three different purposes!
