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.
