Deciding which plants will help growing tomatoes better in the garden offers a lot of options.
Companion planting is part art, part science and folklore. Gardeners with companion plantings report increased harvests; better overall growth, flavor and reduced garden pests. Plus, with today’s smaller gardens, it’s an excellent way to maximize garden space.
Some plants, particularly herbs, act as pest repellents. They confuse insects with strong odors that mask the scent of the intended victim plant.
1. Easy to grow companion plants for tomatoes
Consider easy to grow companion plants such as: Asparagus, Basil, Borage, Carrots, Chives, Dill, Lettuce, Marigolds, Nasturtium, Onions, Parsley, Radishes, Spinach or Thyme.
