Imagine biting into a sun-warmed tomato, bursting with flavor, and knowing you helped make it the best it could be. That's the magic of companion planting! Growing tomatoes isn't just about the tomatoes themselves; it's about the entire garden ecosystem you create around them. And strategically choosing what to grow alongside tomatoes for better yields can make a significant difference in taste, overall plant health, and even how much space you need.
Why bother with companion planting for your tomatoes? It's more than just an old wives' tale. Certain plants naturally enhance tomato growth and flavor, some deter pests, others improve soil conditions, and some even act as living trellises! You can drastically improve your tomato harvest by understanding these relationships. Plus, if you are limited on space, using companion planting in raised beds, containers or in the ground, is an efficient way to get more out of your garden!

Companion Planting for Tomato Success
Companion planting isn't just about aesthetics, although a well-planned garden is certainly beautiful. It's about creating a mutually beneficial environment where plants support each other. When it comes to what to grow alongside tomatoes for better yields, consider the following: pest control, nutrient cycling, space optimization, and even flavor enhancement! Tomatoes are heavy feeders, so finding plants that can improve nutrient availability in the soil is extremely helpful.
The Best Companions for Your Tomatoes
Let's dive into some specific plants that make excellent companions for tomatoes: Basil: As mentioned earlier, basil is a superstar. It's thought to improve tomato flavor and repel pests like tomato hornworms and whiteflies. Marigolds: These cheerful flowers are known for their ability to deter nematodes and other soil pests. Choose French marigolds (Tagetes patula) for the best effect. Carrots: Carrots loosen the soil, which helps water drain more easily, and tomatoes repel carrot root flies. Garlic and Onions: These alliums have strong scents that deter many pests, including aphids and spider mites. Nasturtiums: These edible flowers act as a trap crop, attracting aphids away from your tomatoes. They also attract beneficial insects like ladybugs. Borage: Borage attracts pollinators, like bees, which are crucial for tomato production. It also deters tomato hornworms. Beans: Legumes, such as bush beans or pole beans, fix nitrogen in the soil, providing a valuable nutrient for your tomatoes. Trellis pole beans nearby to save space. Lettuce and Spinach: These leafy greens can be planted at the base of tomato plants, utilizing the shade provided by the tomatoes during the hottest part of the day.
Plants to Avoid Planting Near Tomatoes
Just as some plants are beneficial, others can hinder tomato growth. Avoid planting these near your tomatoes: Brassicas (Cabbage, Broccoli, Cauliflower): These plants compete for nutrients and can attract pests that also attack tomatoes. Fennel: Fennel is allelopathic, meaning it releases chemicals that inhibit the growth of other plants, including tomatoes. Potatoes: Potatoes and tomatoes are susceptible to similar diseases, such as blight, and can compete for nutrients. Corn: Corn attracts the tomato fruitworm/corn earworm, which damages tomatoes. Walnut Trees:Walnut trees release a substance called juglone that is toxic to many plants, including tomatoes.
Tomato Growing Basics: Site, Soil, and Sunlight
Before you start planting companions, let's cover the fundamental requirements for healthy tomato growth. Tomatoes are sun-loving, heat-tolerant plants that need well-drained soil.
Sunlight: Tomatoes need at least 6-8 hours of direct sunlight per day. Choose a location in your garden that receives plenty of sun. If you're growing indoors, you will need grow lights. Look for full-spectrum LED grow lights and position them a few inches above the seedlings. A timer to provide 14-16 hours of light is beneficial. Soil: Tomatoes prefer well-drained, slightly acidic soil with a p H between 6.0 and
6.8. Amend your soil with compost or other organic matter to improve drainage and fertility. For containers, use a high-quality potting mix. Containers vs. Ground:Tomatoes grow well in containers, raised beds, or directly in the ground. If growing in containers, choose a pot that is at least 5 gallons in size. For raised beds or in-ground planting, space plants 2-3 feet apart.
Watering, Feeding, and Pruning Your Tomatoes
Proper watering, feeding, and pruning are crucial for maximizing your tomato yield.
Watering: Water deeply and regularly, especially during hot weather. Avoid overhead watering, which can promote fungal diseases. Mulching around the base of the plants helps retain moisture and suppress weeds. Aim for consistent soil moisture to prevent blossom end rot. Feeding: Tomatoes are heavy feeders and benefit from regular fertilization. Use a balanced fertilizer (e.g., 10-10-10) or a tomato-specific fertilizer. You can also use organic fertilizers like compost tea or fish emulsion. Pruning:Prune suckers (the small shoots that grow in the "v" between the main stem and branches) to improve airflow and encourage fruit production. This is especially important for indeterminate tomato varieties, which continue to grow throughout the season. Determinate varieties don't need as much pruning, as they are more compact.
Addressing Common Tomato Growing Problems
Even with the best planning, you may encounter some common tomato growing problems. Here are a few and some quick fixes: Yellowing Leaves: Can be caused by nutrient deficiencies (especially nitrogen), overwatering, or disease. Check your soil's p H and nutrient levels, adjust your watering schedule, and treat any diseases promptly with an organic fungicide. Slow Growth: Insufficient sunlight, poor soil, or cold temperatures can stunt tomato growth. Ensure your plants are getting enough sun, amend your soil with compost, and protect them from frost. Pests: Tomato hornworms, aphids, and spider mites can damage your tomato plants. Handpick hornworms, use insecticidal soap for aphids and spider mites, and attract beneficial insects to your garden. Pollination Issues: In hot weather, tomato blossoms may not set fruit due to poor pollination. Gently shake the plants in the morning to encourage pollination.
Harvesting Your Tomatoes and Enjoying the Bounty
Harvest tomatoes when they are fully colored and slightly soft to the touch. The flavor will vary depending on the variety, but the ripest tomatoes will have a richer, sweeter taste.
Now that you’re armed with knowledge about what to grow alongside tomatoes for better yields, your next step is to plan your garden layout. Consider which companions will provide the most benefits and start planting! Don’t be afraid to experiment and see what works best in your specific climate and growing conditions.
FAQ: Companion Planting for Tomatoes
What are the main benefits of companion planting with tomatoes?

Both raised beds and in-ground planting can work well for tomatoes. Raised beds offer better drainage and soil control, while in-ground planting can be more economical and natural.
How often should I water my tomatoes?
Water deeply whenever the top inch of soil feels dry. Frequency depends on weather, soil type, and plant size, but aim for consistent moisture to prevent blossom end rot.
What is the best fertilizer for tomatoes?
Use a balanced fertilizer or a tomato-specific fertilizer that is high in phosphorus and potassium. Organic options like compost tea or fish emulsion are also effective.
What can I do if my tomato plants are not producing fruit?
Ensure your plants are getting enough sunlight, water, and nutrients. Check for pollination issues and hand-pollinate if necessary. Also, protect plants from extreme temperatures, as they can inhibit fruit set.
