Almost all vegetables can be grown in containers and vegetable container gardening can yield a ton of veggies to boot! One of the best parts of vegetable container gardening is that if a plant isn’t doing so hot in a particular space, you can move it! The hardest part about container gardening is picking out which plants you want to grow and the size of the container to put them in.
Vegetable Container Gardening
There are a few key things to remember when picking out containers for your vegetable garden. If you live in a very hot climate, make sure to choose hard plastic over soft as the heat transfers quickly to the plant’s roots and can fry them. It is best to use thick plastic, Styrofoam, terra cotta or ceramic containers if you are battling extreme heat. Same thing if you are gardening on a rooftop or balcony – you will want to stick with materials that are lighter rather than something heavy like a big clay pot.
Before you pick out your vegetables make sure your containers have good drainage hole, at least 3-4 on the bottom with a layer of rocks on top. Next add in a good potting soil that you have added bone meal, blood meal, and earthworm castings to. Since you are gardening in such a small space those plants need to be able to uptake as many nutrients as they can. You will want to add this same mixture as the soil line goes down over time.
Choosing the proper container for the type of plant you have is essential. Look to plant vegetable container gardens in pots that are least 10 inches wide and 12 inches deep. Large flowerpots, half barrels, window boxes and planters, plus large containers such as 5-gallon buckets work best. Use large 25-gallon pots for either dwarf citrus trees like Meyers Lemon and even a 5-gallon painter bucket is the perfect size to grow vegetables like tomatoes or squash. Grow root vegetables like carrots and radishes in a deep 10-15” tall pot.
