How can I effectively plant cilantro alongside tomatoes in my garden?

To effectively plant cilantro alongside tomatoes in your garden, choose a sunny spot with well-draining soil. Plant the tomatoes first, leaving enough space between each plant for the cilantro. Sow cilantro seeds directly into the soil, about 1/4 inch deep and 6 inches apart. Water regularly and ensure both plants receive adequate sunlight and nutrients. Harvest cilantro leaves as needed, being careful not to disturb the tomato plants.
