Top Picks and Pitfalls for Tomato's Garden Buddies
=============================================================================
Growing tomatoes can be a rewarding experience, but ensuring a bountiful harvest requires careful consideration of the plants surrounding them. Here's a guide to the best and worst companion plants for tomatoes, to help you create a thriving vegetable garden.
The Best Companions for Tomatoes
- Basil: Basil not only enhances the flavour of tomatoes, but it also increases their root size and fruit yield. It acts as a natural repellent for pests such as aphids and hornworms.
- French Marigolds: These vibrant flowers are excellent at repelling nematodes and various pests, promoting healthier tomato growth.
- Garlic and Onions: These strong-smelling plants deter aphids, thrips, whiteflies, and other pests, while garlic also has antifungal properties that protect soil-borne diseases.
- Asparagus: Asparagus beetles, a common pest, are deterred by tomatoes, and vice versa. This mutual pest protection makes these plants ideal companions.
- Beans: Beans fix nitrogen in the soil, improving tomato growth and reducing diseases when interplanted.
- Borage: Borage attracts beneficial parasitic wasps to control aphids and hornworms, improves tomato taste, and enhances disease resistance.
- Carrots: Carrots loosen the soil, making it easier for tomato roots to expand.
- Celery and Parsley: These plants repel pests and attract beneficial insects that protect tomatoes.
- Radish: Radish acts as a trap crop for flea beetles, protecting young tomato seedlings.
Plants to Avoid with Tomatoes
- Potatoes: Potatoes compete with tomatoes for nutrients and can harbour pests.
- Fennel: Fennel produces a chemical that inhibits root and plant growth, causing stunted growth and smaller fruits in tomato plants.
- Corn: Corn and tomatoes share the same pests, attracting nibbling pests and causing extensive damage.
- Cabbage and relatives: Cabbage and tomatoes do not complement each other and can lead to stunted growth when grown side by side.
Mixing it Up
- Leaf Lettuce: Leaf lettuce inhibits the spread of diseases caused by rot and helps control weed growth. Tomatoes deter pests and save space.
- Flowers: Mixing flowering plants with herbs and vegetables can deter or confuse pests. Some flowering plants attract beneficial insects to the garden.
- Eggplants: Eggplants and tomatoes are vulnerable to early and late blight when grown together, causing blight to build up in the soil and spread throughout the garden.
- Marigolds: Marigolds protect tomatoes from pests like root-knot nematodes, tomato hornworms, whiteflies, and thrips.

Incorporating technology into your home-and-garden, you might consider using data-and-cloud-computing platforms to optimize your growing conditions, predict potential pests, and provide tailored advice based on your specific climate and planting preferences. For instance, you could use apps to track soil conditions, or weather forecasting tools to predict temperature changes that would affect your tomato plants. This lifestyle choice, merged with traditional gardening methods, could lead to a thriving home-and-garden environment. Meanwhile, careful consideration must be given to your chosen plant companions - some technologies, like fennel, can inhibit the growth of tomatoes, while plants like basil, French marigolds, and borage can enhance the health and yield of the tomatoes.
