Intercropping tomatoes means growing two or more crops in the same space at the same time. This method of growing crops is a way of increasing the harvest, improving soil health, and reducing pests and diseases.
Intercropping has been used for centuries, and it’s still popular among modern-day farmers and gardeners because it works so well.
Today, we’ll look at the benefits of intercropping tomatoes and how to do it effectively.
Benefits of Intercropping Tomatoes
Intercropping tomatoes with other crops can increase the productivity of your garden. This is because intercropping maximizes the use of space, water, and nutrients. By growing two or more crops in the same area, you can achieve a higher yield.
Improved soil health
Intercropping helps to improve soil health by increasing soil fertility and reducing soil erosion. When different crops are grown together, they take up different nutrients from the soil, resulting in a reduction of the depletion of soil nutrients. Also, intercropping can help to control soil erosion by providing ground cover.
Pest and disease control
Intercropping can help to reduce pests and diseases by creating a diverse ecosystem. When different crops are grown together, they can confuse pests and reduce the spread of diseases.
For example, intercropping tomatoes with herbs like basil can help to repel insects that attack tomato plants.
Intercropping can help to suppress weeds by creating a dense canopy that shades out the weeds. Also, some crops like legumes can fix nitrogen in the soil, which helps to reduce weed growth.

How to Intercrop Tomatoes
Choose the right companion crops
When intercropping tomatoes, it’s important to choose the right companion crops. You should select crops that complement tomatoes in terms of nutrient requirements, growth habits, and pest and disease resistance.
Some good companion crops for tomatoes include:
Plan your garden layout
Before planting, you should plan your garden layout to maximize space and ensure that all crops have enough room to grow.
You should consider the growth habits of each crop and plant taller crops like tomatoes and corn on the north side of the garden to prevent the shading of shorter crops.
Prepare the soil
You should prepare the soil before planting by adding organic matter and ensuring that the soil has a balanced pH. Tomatoes grow best in well-drained, fertile soil with a pH of 6.0-7.0.
Plant your crops
When planting, you should ensure that each crop has enough room to grow and that its root systems don’t compete for water and nutrients. You should also avoid planting crops that have similar nutrient requirements next to each other.
For example, you should not plant tomatoes next to peppers as they both require high amounts of potassium.
Monitor and manage pests and diseases
Intercropping can help to reduce pest and disease pressure, but you still need to monitor your garden regularly and manage any outbreaks. You should use organic methods to control pests and diseases, such as using insecticidal soap and neem oil.
Harvest your crops
When it’s time to harvest your crops, you should be careful, so you avoid damaging the plants. You should also remove any diseased or damaged plants to prevent the spread of diseases.
9 Tips for Successful Intercropping
- Rotate your crops: To avoid soil depletion and reduce pest and disease pressure, you should rotate your crops every season. This means that you should not plant the same crops in the same area for two consecutive seasons.
- Use companion planting charts: Companion planting charts can help you choose the right companion crops for your tomatoes.
- Timing: It’s important to time your intercropping correctly. You should select companion crops that have different growth rates and maturity periods so that they don’t compete for resources. For example, you can plant quick-maturing crops like lettuce and radishes between slower-growing crops like tomatoes and peppers.
- Spacing: Proper spacing is critical for successful intercropping. You should space your plants based on their growth habits and needs. For example, you can plant tomatoes 18-24 inches apart and intercrop them with herbs like basil or cilantro, which can be planted in between the tomato plants.
- Watering: Intercropped plants may have different water requirements, so you should water them appropriately. You should avoid overwatering as this can lead to soil erosion and nutrient leaching.
- Fertilization: Intercropping can benefit from organic fertilizers such as compost or manure, which can help to improve soil health and provide nutrients to the plants. You should also avoid over-fertilizing, which can lead to nutrient imbalances and other issues.
- Crop selection: Select crops that complement each other and have similar growing requirements. For example, you can intercrop tomatoes with crops like beans, peas, or cucumbers, which fix nitrogen in the soil and provide support for the tomato plants.
- Plant diversity: Intercropping with a diverse range of crops can help to create a more resilient ecosystem that is less vulnerable to pest and disease outbreaks. You can intercrop with a mix of vegetables, herbs, and flowers to create a diverse and beautiful garden.
- Observation: It’s important to observe your garden regularly to detect any problems that may arise. This can include monitoring for pests and diseases, checking for nutrient deficiencies, and ensuring that the plants are growing properly. Keeping a record of what and when you find these things can help you in the years to come.
