Cool-Season Veggie Garden in Pots

Although many people like the idea of growing their own vegetables, the thought of creating and maintaining an entire garden can be intimidating. What better way to start than by growing vegetables in containers? Many cool-season vegetable crops are easily grown in pots, adding a splash of color to any porch or patio, and providing homeowners with a rewarding gardening experience.

Spinach, cauliflower, lettuces, cabbages, cauliflowers, chard, and broccoli perform well in containers. Even carrots can be successfully grown in a deeper pot. Plants thrive if provided with well-prepared, well-drained potting mix, plenty of water, and supplemental fertilizer. When choosing plants for the containers, pick small versions of typically large plants, such as dwarf or compact cultivars. The potting mix used should be lightweight and soilless. Consider incorporating a controlled-release fertilizer to avoid the need for fertilizing often.

When placing the containers, consider elevating pots on wooden blocks or bricks to encourage drainage. In addition, think carefully about where the containers will be located. Vegetables need plenty of sun, place the pots in a sunny spot. Drainage is necessary to prevent root rot in the plants, but the extra water may need to be diverted for safety reasons. A windy spot may mean the plants get beaten down and may not perform as well.

Locating container plants in a roof garden may result in structural damage to the building if the roof is not sturdy enough to handle the weight of the pots. Remember, the pots will be much heavier with the added weight of water. It may be helpful to wait until the container has reached its permanent position before watering transplants.

When planting in containers, gardeners should always remember to plan for the full-grown size of the plants chosen. This prevents gaping holes as well as over-filled containers. Plants should be of similar size when initially planted so the plants grow together to fill the space. It may be best to use transplants so the plants are well established when they first go in the container.

Some plants will weather a light frost and should keep producing afterwards provided they are protected from serious damage. A light covering of plastic, cardboard or cloth should sufficiently protect the plant from chill temperatures and frost. Keeping the plants covered prevents cold air from being able to reach the plants. Another good option is placing the plants in a cold frame to protect them.

Give plants adequate water and keep them pinched back and bushy, and they should thrive. Watch for insect pests and diseases, and treat as needed. Harvest vegetables as you normally would, and enjoy the fruits of your (not-so-hard) work.
