The best soil mix for your container-grown vegetables is one that is well-drained, well-aerated and has a pH that is close to neutral. Soil-containing or soilless potting mixes offer all of these features.
Vegetables that are ideally suited for growing in containers include. tomatoes, peppers, eggplant, green onions, beans, lettuce, squash, radishes and parsley.
