Carrots are a popular root vegetable, and they can also be an excellent companion plant in your garden. They can thrive in the same garden bed with cool-season crops, such as radishes, lettuce, and spinach, which can provide shade and help regulate the soil temperature.

  • To ensure a consistent supply of fresh carrots throughout the growing season, it is recommended to sow carrot seeds every two to three weeks.
  • Carrots are known to attract beneficial insects such as ladybugs, lacewings, and parasitic wasps, which can help control pests such as aphids, spider mites, and caterpillars.
  • Planting carrots near other crops, such as tomatoes, peppers, and onions, can help to deter harmful insects and improve plant health. Carrots and peppers companion planting is a great way to get started.
  • Carrots also produce a chemical called alpha-pinene, which has been shown to repel certain pests such as root maggots and flea beetles. Planting carrots in combination with other alpha-pinene-producing plants such as basil, dill, or parsley can help to repel these pests further.
