Can I Plant Jalapenos Next to Tomatoes?

Tomatoes and jalapenos, both members of the nightshade family, can indeed be grown together. However, careful planning and management are essential to ensure the health and productivity of both plants. They share some risks, such as attracting similar pests and depleting similar nutrients from the soil. Yet, many backyard gardeners have successfully grown them together by implementing proper pest management, soil nutrition, and spacing strategies.

Benefits of Planting Jalapenos Next to Tomatoes

Planting jalapenos next to tomatoes can offer several benefits. Both plants thrive in similar conditions, requiring full sun, well-draining soil, and consistent watering. This means they can share a watering schedule and similar soil amendments, making garden maintenance more straightforward.

Companion planting tomatoes and peppers can also lead to increased yields. The plants can benefit from each other’s presence, improving soil conditions and attracting beneficial insects. For instance, tomatoes can provide some shade to pepper plants, protecting them from the harsh afternoon sun in hotter climates.

Considerations for Planting Jalapenos Next to Tomatoes

While there are benefits to planting jalapenos next to tomatoes, there are also considerations to keep in mind. Both plants can attract similar pests, and diseases can easily spread between them. To mitigate these risks, avoid overcrowding, water at the base of the plants to prevent wet foliage, maintain proper airflow, and choose disease-resistant varieties.

Another important consideration is the height difference between tomato and pepper plants. Tomato plants can grow much taller than jalapenos and may shade the peppers too much if not properly spaced. Ensure that your jalapeno plants are not being overshadowed by your tomato plants, as this can reduce their sun exposure and affect their growth.

Seed Saving and Cross-Pollination

If you plan to save seeds from your plants for future planting, be aware that peppers and tomatoes can cross-pollinate. This is especially true if they are planted very close together. Cross-pollination can result in seeds that produce plants with characteristics of both parent plants. If you want to maintain the purity of your seeds, consider planting different varieties further apart or using barriers like row covers.

Other Plants to Avoid Near Jalapenos

While tomatoes can make good companions for jalapenos, there are some plants that you should avoid planting near your peppers. These include beans and brassicas like cabbage and kale. These plants can inhibit the growth of pepper plants or attract pests that peppers are susceptible to.

How Far Apart Should Peppers and Tomatoes Be Planted?


The recommended spacing between pepper and tomato plants is about 24 inches. This allows enough room for each plant to grow and reduces the risk of disease transmission.

Can You Cross Pollinate Tomatoes and Peppers?

While it’s possible for tomatoes and peppers to cross-pollinate, it’s relatively rare and usually doesn’t affect the fruit that grows that season. Instead, the cross-pollination will affect the seedsinside the fruit and the plants that grow from those seeds in the next generation. If you’re not saving seeds, you don’t need to worry about cross-pollination.

Do Peppers Need More Sun Than Tomatoes?

Both peppers and tomatoes love the sun and need a minimum of 6-8 hours of sunlight each day. However, in very hot climates, peppers might appreciate a bit of afternoon shade to prevent sunscald.

In conclusion, you can plant jalapenos next to tomatoes with some considerations. Proper spacing, pest management, and attention to each plant’s needs can result in a successful and productive garden. Remember, every garden is unique, and what works best may depend on your specific conditions, including soil, climate, and the particular varieties of tomatoes and peppers you are growing. Happy gardening!
