Different from growing berries, vines, or crops a vegetable garden requires only a bit of shift. Any gardening experience that you bring to your new vegetable garden will help your experiment. Keep in mind that not all garden crops will thrive, and annual veggies require some weekly and possibly daily maintenance during the approximately three month summer growing season.
First thought for growing specifically vegetables is the proximity to your living quarters. If you are growing at a community garden plot, then you have to bring all supplies along for your work. If the garden is within sight of your back door, start composting now! There are a variety of composting methods to choose from, and if done well, can be a great stinky corner of your garden.
Water is hard to drag across a parking lot, so be preemptive about your vegetable gardens location. With location chosen, dig in. If the garden bed is new you will need to prep the soil by tilling, fertilizing, and maybe filling in with superior growing medium (soil). Depending on what types of vegetables you are trying to garden, it might be simpler to use pots. If two tomato plants is the extent of your wishes, or if you want to start small, then I would encourage container gardening. If you have your mind set on a in-the-ground garden bed, then you need to decide how deep to dig it. Carrots need carefully prepared soil, as they are roots and can mis-form around rocks. Depth is important for root vegetables like parsnips, carrots, beets, and horseradish.
Other garden vegetables grow almost like weeds. One needs to be careful about the mint family. Spearmint, peppermint, and catnip will take over an area within one growing season. They spread so rapidly you won’t have enough lemonade all summer to smoosh mint leaves in.
If your garden is designed to large, you will have to walk through it to tend it. This is a mess, so if your rows can be planted so that you can reach every plant from outside the vegetable garden it is best. Rows can be long or multiple depending on vegetable. I have found that carrots are prone to a type of root rot that only affects some parts of the garden. Either the rot is localized or the conditions where those plants are is different (like too wet or sandy).
A vegetable garden is an experiment with often bountiful results. Some crops will fail, and without a good first attempt it is hard to motivate to ever do it again, so learn as much as you can here online and then just go out and plan to spend some time each evening keeping your vegetable garden weed free and with plenty (although not too much) water. You are a vegetable gardener.
