So you don’t have space for an in-ground garden. That’s no reason to give up on growing food at home. You can absolutely grow vegetables in containers!

Growing veggies in containers is only a little different from growing in the ground or raised beds. And there are lots of advantages to container gardening.

Container gardens do not have to battle weeds, can be placed in any location, and they don’t have to take up very much space.

Five tips for growing vegetables in containers

Here are some tips for getting good results from your veggies grown in pots.

Choose an appropriately sized container.

Make sure your container is large enough to provide adequate space for your plant’s roots. The larger the adult plant, the larger the pot.

Larger containers mean you’ll have plenty of space for the roots to spread out. Stunted space for root growth leads to stunted plants. Smaller containers will also require more frequent watering and fertilization.

Choose an appropriate location

The ability to place your garden in the perfect location is one of the advantages of growing vegetables in containers. The perfect location is completely dependent on the vegetable you grow.

Tomatoes, peppers, and eggplant love full sun. Spinach and lettuce, on the other hand, will appreciate some protection from the hot afternoon sun.

Use potting soil not garden soil

Whatever you do, do not use soil from your yard in containers. The soil from your yard will contain sticks, rocks, weeds, and bugs. Potting soil needs to be free of these things.

Purchase a high-quality potting soil like Foxfarm Ocean Forest, and you will need to fertilize less often. Or you can make your own potting soil with a mix of peat moss, perlite, and compost (+/- lime to adjust pH as needed).

Make sure you have good drainage

Always use a container with a drainage hole. Your plants will be smothered by the excess water if there is no place for it to drain.

This is another reason to choose a good potting soil that will have a good balance of drainage and water retention.

When you’re growing plants for food, give them the best chance by filling your container completely with soil. Resist the temptation to improve drainage by adding cans, rocks, or other items in the bottom of your container. Choose a high-quality garden soil instead.

Fertilize, fertilize, fertilize

In any food garden, you have to make sure you have adequate nutrients for your plants to thrive. Here again, the first step is choosing a good quality potting soil or compost.

When you do need to fertilize, use organic fish emulsion fertilizer. It stinks to high heaven, but it makes your plants so happy! Use a hose end sprayer to apply it quickly and evenly with no smelly mess.

Watch your plants for signs they need fertilizer like slow growth, no fruit, and pale or yellow leaves.

When growing vegetables in containers, you will get better results if you apply fertilizer regularly.

How much food can you grow in containers?

You can grow as much or as little of your food in containers as you would like! Don’t limit yourself to tomatoes and peppers, you can even grow okra in a container!

If growing food for your family is your goal, don’t overfill your containers with plants.

They won’t look as lovely as containers overflowing with the thrill-fill-spill method, but vegetables need to have their space in order to achieve the highest level of food production.

Crowded plants compete for nutrients, water, and root space and will increase your pest or disease issues. Dedicate each container to one main food crop and a couple smaller companion plants.
