Key Takeaways
- Marigolds repel nematodes and beetles, protecting tomato plants from pests.
- Borage attracts beneficial insects and enriches soil with essential nutrients.

Planting companion plants alongside your tomatoes can boost their health and yield by naturally repelling pests, improving soil quality, and providing shade. When you choose the right companions, you create a balanced garden ecosystem that minimizes the need for chemical interventions. One of the key benefits is pest control; certain plants emit odors or compounds that deter common tomato pests like aphids, whiteflies, and tomato hornworms. Marigolds, for example, release substances that repel nematodes and beetles, helping keep your tomatoes safe from infestations. Borage also acts as a trap crop for pests, drawing them away from your main crop while enriching the soil with nutrients like potassium and calcium, which are essential for tomato growth.
Soil enrichment is another indispensable aspect when selecting companion plants. Some plants actively improve soil quality, making it more fertile and better suited for tomatoes. Leguminous plants like beans and peas fix nitrogen from the atmosphere, transferring it into the soil through their roots, which feeds your tomatoes naturally. This reduces the need for synthetic fertilizers and promotes healthier, more vigorous plants. Additionally, herbs like basil and cilantro can enhance soil microbial activity, creating a more fertile environment for root development. These herbs not only contribute to pest control but also boost the overall soil health, leading to stronger, more productive tomato plants.
Providing shade is an often-overlooked benefit of certain companion plants. Taller plants like corn or sunflowers can cast partial shade over your tomatoes during the hottest parts of the day, reducing heat stress and water loss. This is especially beneficial in warmer climates or during heatwaves. By strategically planting these taller companions nearby, you help your tomatoes maintain better moisture levels and prevent sunscald on fruits, resulting in higher quality and quantity of harvest.
