Benefits of Planting Together

Planting tomatoes, lettuce, and nasturtiums together offers several advantages. Nasturtiums repel pests like aphids and whiteflies, reducing the need for chemical pesticides. Lettuce can benefit from the shade provided by taller tomato plants, preventing bolting in hot weather. This combination also maximizes space efficiency in smaller gardens. Additionally, nasturtiums attract pollinators, enhancing the yield of tomatoes.

Potential Challenges

While these plants can be grown together, there are potential challenges. Tomatoes and lettuce have different water needs, with lettuce requiring more frequent watering. Competition for nutrients can occur if the soil is not properly managed. Disease susceptibility, such as fungal infections, may increase in crowded conditions. To overcome these issues, ensure adequate spacing, monitor watering, and practice crop rotation.

Planting Tips & Best Practices
