Bushy and vining plants such as tomatoes, peas, and beans will need some support as they grow and their veggies develop. Use a cage for potted tomatoes, eggplant and other bushy veggies, and as the plant grows, guide the branches through the supports. The branches will rest on the cage instead of eventually buckling toward the ground under its own weight. This also keeps the developing fruits off the ground where they can develop rot. A trellis can provide vertical support for vining veggies like peas, beans, and squash that twine themselves upward. There are many different designs of cages and trellises, and you may find your veggie may need some added assistance from string or a twist-tie to hold it secure.
