How Close Can I Plant Tomatoes and Basil?

Tomatoes and basil are two classic plants that complement each other well in recipes and in the garden. They also have a symbiotic relationship in the garden, with basil acting as a natural pest repellent for tomato plants. However, many gardeners wonder how close they can plant these two crops together. Here are some tips on planting tomatoes and basil together.

Consider the Size of Your Plants

Before planting tomatoes and basil side by side, consider the size of your plants when they reach full maturity. Tomatoes typically require more space due to their sprawling size and need for support structures. Basil, on the other hand, is a smaller plant that can easily be squeezed in between tomato plants. As a general rule, space tomato plants at least 18-24 inches apart and basil plants 6-12 inches apart to ensure they have enough room to grow and thrive.

Think About Water and Nutrient Needs

Tomatoes and basil have different water and nutrient needs, so it's important to consider this when planting them together. Tomatoes require consistent moisture and frequent fertilization, while basil prefers well-draining soil and minimal fertilization. To make sure both crops thrive, water your tomato plants deeply once a week and fertilize them with a balanced fertilizer every few weeks. For basil plants, water them regularly but avoid overwatering, and fertilize only once or twice during the growing season.

Plant at the Right Time

Timing is also important when planting tomatoes and basil together. Tomatoes are warm-season plants that thrive in hot weather, while basil prefers cooler temperatures. To ensure both crops develop properly, plant your tomato plants once the soil has warmed to at least 60 degrees Fahrenheit and the danger of frost has passed. Basil can be planted anytime once the soil has reached 50 degrees Fahrenheit or higher, but it's best to wait until after the last frost to plant to avoid potential damage.

Don't Overcrowd Your Garden

While it's tempting to maximize your garden space by planting as many crops as possible, overcrowding can lead to poor growth and yield for both tomatoes and basil. Allow enough space between plants for good air circulation and sunlight exposure, and avoid planting other crops too close to your tomato and basil plants. This will help prevent disease and pest problems and ensure that each plant has the resources it needs to thrive.

Final Thoughts

Tomatoes and basil are great plants to grow together, and with a little planning and care, you can enjoy a bountiful harvest of both crops. Keep these tips in mind when planting tomatoes and basil together to ensure they have the space, water, and nutrients they need to thrive.
