March marks the beginning of the planting season for many gardeners eager to grow fresh vegetables and herbs. Among the most popular crops to start early indoors or in protected environments are tomatoes. To enhance tomato growth and flavor, planting companion herbs alongside them can be highly beneficial. These herbs can improve pest resistance, boost growth, and add aromatic flavor to your garden.
Why Use Companion Herbs with Tomatoes?
Companion planting is an age-old gardening practice that involves growing certain plants together to benefit each other. When you plant herbs alongside tomatoes, you can:
- Repel pests such as aphids, whiteflies, and tomato hornworms.
- Improve soil health with natural pest deterrents and attract beneficial insects.
- Enhance the flavor and aroma of your tomatoes.
- Provide ground cover that helps retain soil moisture and suppress weeds.
Best Companion Herbs for Tomatoes in March
When starting your tomato seeds in March, consider planting these herbs nearby or in containers that can be moved outdoors as the weather warms:
Basil
Basil is one of the most popular herbs to grow with tomatoes. It repels pests like mosquitoes and flies, and its aromatic leaves can enhance the flavor of your ripe tomatoes. Plant basil seeds indoors in March or transplant seedlings outdoors once the danger of frost has passed.
Parsley
Parsley attracts beneficial insects such as hoverflies, which prey on pests that attack tomatoes. It also acts as a ground cover, helping to retain moisture and suppress weeds. Start parsley seeds indoors in early March for transplanting later in spring.
Cilantro
Cilantro, or coriander, attracts predatory insects that help control tomato pests. Its quick germination makes it a good choice for early planting. Sow cilantro seeds indoors in March to get a head start before transplanting.
Additional Tips for March Seed Starting
Starting your tomato and companion herbs indoors in March requires attention to detail:
- Use quality seed-starting soil and containers with drainage.
- Provide ample light, ideally with grow lights if natural sunlight is limited.
- Maintain consistent moisture without overwatering.
- Harden off seedlings gradually before transplanting outdoors.
Conclusion
Starting your tomato seeds in March offers a head start for a productive garden season. Incorporating companion herbs like basil, parsley, and cilantro can improve plant health, reduce pests, and enhance flavor. With careful planning and early planting, you’ll enjoy a bountiful harvest of delicious tomatoes and fragrant herbs later in the season.
