Can You Plant Tomatoes And Kale Together


Tomatoes and kale are two of the most popular vegetables grown in the home garden. These plants can provide an abundance of delicious produce, and growing them together can help maximize space in the garden. But do these two plants work well together when grown in the same plot? Growing tomatoes and kale together is possible, and it does have some advantages and disadvantages. In this article, we’ll take a look at the pros and cons of planting tomatoes and kale together. We’ll also offer some advice on how to make co-planting successful and how you can maximize the yield of each of your plants without damaging the other.

Growing Conditions

Before planting tomatoes and kale together, one should take a look at the growing requirements of each of the plants. Tomatoes prefer ample sunlight and heat, along with full soil fertility and moisture. Kale too needs plenty of sunlight, but it also needs consistently moist, fertile soil and protection from the wind. Both of these plants must also be kept disease and pest free, otherwise the plant growth can be negatively impacted.


When planting tomatoes and kale together, timing is everything. Tomatoes should be planted after all danger of frost has passed, as they are a warm season plant. Kale is a cool season plant, and can tolerate light frosts. To take full advantage of the growing seasons of both plants, it is best to pick a variety of each that is suitable for the time of year they will be planted.


To make co-planting successful, it is important to provide adequate spacing between the two plants. Tomatoes need plenty of room to grow, and so the plants should be kept at least two feet apart. Kale plants, on the other hand, can be planted closer together, no more than a foot apart from the next plant. This spacing will help ensure that each plant has adequate access to sunlight, water, and nutrient levels, as well as helping to reduce the chances of disease and pest infestations.

Companion Planting

When planting tomatoes and kale together, it is important to remember the concept of companion planting. This means that certain plants can complement each other and provide beneficial effects when planted near one another. This can occur in many ways; one way is that certain plants can provide natural pest control, while other may produce beneficial chemicals that boost the growth of their neighboring plants. Good companion plants for tomatoes and kale include garlic, onions, and oregano, all of which offer different types of pest control and protection.

Pruning and Harvesting

When growing tomatoes and kale together, it is important to keep an eye on the plants and prune them whenever necessary. Tomatoes, for example, can become unruly, sprawling plants that can take over the garden and shade out the kale. Pruning and staking the tomato plants can help make sure that the plants remain in control and the kale has enough space to grow and thrive. Don’t forget to harvest the tomatoes and kale when ready – tomatoes should be harvested when they are full-colored, and kale can be harvested when the leaves are a rich green color.

Advantages and Disadvantages

The great thing about planting tomatoes and kale together is the fact that they can provide a supplemental boost of nutrition to one another. Kale, for example, is a great source of calcium, iron, and vitamins, and it can help to provide additional nutrition to the tomatoes. On the other hand, tomatoes are rich in antioxidants, and can help to protect the kale from different types of disease.
The main disadvantage to this type of growing, however, is that the tomatoes can overtake the kale if they are not managed properly. Tomatoes need ample space to grow and spread out, and if the two plants are not adequately spaced they can end up competing for resources. This can lead to a dragged-out harvest as the plants compete for nutrition, with the kale not reaching its full potential.

Soil pH Level

Tomatoes and kale both require slightly acidic soil in order to thrive. If the soil pH level is too high, the plants can suffer from nutrient deficiencies as the nutrients in the soil become locked up and are not available to the plants. Therefore, it is important to check the soil pH level of the area where the tomatoes and kale are planted and make adjustments accordingly.

Mulching and Nutrients

When planting tomatoes and kale together, it is important to incorporate an adequate amount of mulch and other nutrients into the soil. Mulch will help to keep the soil moisture levels consistent, and will also help to keep weeds at bay. Applying compost or other organic matter will help to boost the nutritional levels of the soil and provide the plants with the nutrients they need for vigorous growth.


Proper watering is another essential element when planting tomatoes and kale together. Tomatoes are more sensitive to drought conditions, so they should be given adequate water in order to promote healthy growth and fruiting. Kale, on the other hand, prefers consistently moist soil, so it is important to water it regularly.

Plant Care

Finally, it is important to provide the tomatoes and kale with the proper care. Keep an eye out for signs of disease and pests, and treat the plants accordingly. If the plants become too crowded, thin them out to promote vigorous growth. Planting tomatoes and kale together may take a bit more work and effort, but with careful planning, pruning, and watering, it can be a successful endeavor.
