Companion planting

Sometimes two different plants do well together; sometimes they do not get along. In other instances plants actually help each other grow.

Plants get along with one another in many ways. Sometimes two different plants do well together; sometimes they do not get along. In other instances plants actually help each other grow. In the vegetable garden, it is common practice to grow carrots and peas together as they seem to do better. Tomatoes like parsley and onions. Some plants do not like to be too close together and will stop growing if they are planted with each other. Gardeners soon learned that planting certain plants together helped both plants and eliminated many insect problems.


Grouping plants that benefit each other together is known as "companion planting". Plants with strong smells, such as herbs and certain flowers, can keep insects away so they will not harm the rest of the plants in the garden. If a plant has a scent that is attractive it can attract harmful bugs so it will need a companion plant. The rose is a good example of a beautiful plant that needs good strong companions. This is because aphids attack rose buds every year and can actually suck the juices out of the bud before it can open. You can plant masses of Marigolds. Plant around the rose garden to help in the battle against the aphids. They may not keep all the aphids away, but they will help, and do it naturally.


common companion plantings

  • Potatoes keep Flea beetles away from beans.
  • Marigolds chase Colorado potato beetles away from potatoes. The roots of Marigold give off a substance which drives away the eel-worm so they are good to plant near Potatoes.
  • Radishes planted among the cucumbers discourage cucumber beetles.
  • Rosemary, sage and thyme planted among the cabbage plants repel the cabbage worm.
  • Some stimulate each others growth by physical and energetic means. For instance, Tomatoes & Marigolds like each other.
