Interplanting Tomatoes: How to Increase Yield and Maximize Garden Space

interplanting tomatoes

Tomatoes are one of the most popular crops for beginner and experienced gardeners alike. They are easy to grow, delicious, and versatile in the kitchen. However, space can be a limiting factor when it comes to growing tomatoes. Interplanting is a technique that allows gardeners to maximize the use of their garden space while increasing yield. In this article, we will explore the benefits of interplanting tomatoes and provide tips on how to implement this technique in your own garden.

What is Interplanting?

Interplanting refers to the practice of planting two or more crops in close proximity to each other in the same bed. This technique has several advantages, including:

Disease Prevention

When different crops are planted together, they can create a diverse ecosystem that makes it difficult for pests and diseases to take hold. This is because pests and diseases tend to target specific plants, so by mixing up the types of crops in your garden, you can reduce the risk of an infestation.

Increased Yield

By interplanting crops, you can increase the amount of food you can grow in a given space. This is because different crops have different nutrient needs, so they can complement each other when grown together. For example, legumes fix nitrogen in the soil, which can benefit neighboring plants like tomatoes.

Maximized Garden Space

Interplanting allows you to make the most of your garden space. By planting crops in close proximity to each other, you can reduce the amount of bare soil in your garden, which can help reduce weed growth and soil erosion.

How to Interplant Tomatoes

Now that we've discussed the benefits of interplanting, let's take a closer look at how to implement this technique in your own garden. Here are some tips for interplanting tomatoes:

Choose Complementary Crops

When interplanting tomatoes, it's important to choose crops that will complement them. Some good options include:

  • Basil: Basil is a natural companion to tomatoes because it repels pests like aphids and whiteflies. It also adds flavor to tomato dishes.
  • Marigolds: Marigolds are another natural pest repellent that can help protect your tomatoes from nematodes and other harmful insects.
  • Beans: Beans fix nitrogen in the soil, which can benefit neighboring plants like tomatoes.

Plant at the Right Time

When interplanting tomatoes, it's important to plant at the right time. You want to make sure that your tomatoes have enough space to grow before their neighbors encroaching on their territory.

Provide Adequate Spacing

Even though you're interplanting, it's still important to provide adequate spacing between each plant. This will help ensure that each plant has access to the nutrients and water it needs to grow.

Consider Vertical Gardening

If you're short on horizontal space in your garden, consider growing your tomatoes vertically. This can be by using trellises, stakes, or cages to support the plants as they grow.

Interplanting Tomatoes: Pros and Cons

Like any gardening technique, interplanting tomatoes has its pros and cons. Here are some things to consider:


- Increased yield
- Maximized use of garden space
- Reduced risk of pests and diseases


- Can be difficult to manage if the wrong crops are planted together
- May require more planning and maintenance than traditional gardening methods
