Tomato is a common vegetable in summer, and its growth characteristics and demand conditions determine that it should be adaptable to the vegetables it grows. Tomatoes thrive and need sunny and well-drained soil. When choosing vegetables next to tomatoes, we can consider the following suitable plants: 1. Green leafy vegetables, such as spinach, oily wheat, lettuce, etc. They don't need high sunlight, they can grow in the shadow of tomatoes and don't interfere with each other. 2. Stems: such as celery, lettuce and water spinach. Their growth habits are similar to those of tomatoes, and their roots will not compete for soil nutrients. Leguminous plants, such as peas and lentils, can grow with tomatoes. Leguminous plants can improve soil and help provide nutrients by fixing nitrogen. 4. Herbaceous perfume plants, such as basil and mint, can not only add fragrance to the vegetable garden, but also attract beneficial insects and promote the growth of tomatoes to a certain extent.
