Vegetable Container Gardening for Beginners
Written by Kerry Michaels

Growing your own food can bring you both joy and bounty. There's a
simple pleasure in biting into a tomato still warm from the sun—picked
and eaten on the spot. You can grow just about any vegetable in a
container, a practice that can save you lots of money buying produce
at the grocery store. However, vegetable container gardening can be a
frustrating endeavor if your plants don't thrive and produce. The
following tips apply to most vegetables and can help you and your
plants get off to a good start.

Providing the Right Light and Temperature
Most vegetables need full sun, meaning at least six hours of direct
sunlight each day. But some gardeners might overestimate how much sun
an area really gets. For your veggies to thrive, you'll need an
accurate assessment. Check the location every 30 minutes throughout
the day to confirm how long the sun directly hits the spot where you
want to put your vegetable container garden. You can also use a sun
calculator to get an accurate assessment.

If you live in a hot climate, you might need to shade your plants
during the heat of the afternoon, so they don't overheat. Also, it's
best not to use metal or dark-colored containers because they can
become very hot and cook your plant's roots.

On the flip side, many vegetables don’t like cold soil. So if you live
in a cool climate, avoid putting your containers outside full time
until you know the temperature will be reliably warm. For many plants,
the soil needs to be at least 60 degrees Fahrenheit. You can use a
meat thermometer to find out the temperature of your soil. In
addition, always make sure to harden off your plants (gradually
acclimate them to the outdoor conditions) before you put them outside
permanently.

Watering Your Container Garden
Many vegetable plants, such as tomatoes, need lots of water. However,
you don't want to drown your plants. The goal is to keep the soil
evenly moist but not soaking wet.

To figure out whether your plants need water, stick your finger down
into the soil about an inch. If the soil feels dry, add water; if
you're not sure, wait and check later in the day. At the height of
summer, you'll probably need to water at least once or sometimes twice
a day. This is often the most high-maintenance and critical aspect of
vegetable container gardening.

Using Quality Potting Soil
High-quality potting soil is important for vegetables. Don't use soil
from your garden because it will compact in the containers and won't
drain water properly. Also, one of the reasons to garden in containers
is largely to avoid dealing with weeds. But if you use garden soil,
you might be importing weeds into your containers.

Furthermore, studies have shown many benefits to growing produce
organically, including better taste and a higher percentage of
antioxidants and phytochemicals. Organic soil, which has a higher
variety of nutrients than regular potting mixes, comes in a variety of
pH levels and blends geared toward different crops.

Feeding Your Plants
Plants need nutrition to thrive, and their food is fertilizer. If your
soil doesn’t have fertilizer already mixed in, add some several times
throughout the growing season. Many gardeners mix organic, granular
fertilizer into the containers from top to bottom before planting.
Then, every couple of weeks, add diluted liquid fish emulsion or
liquid seaweed to give the plants the nutrition they need. Another way
to add fertilizer is to make or buy compost.

Creating Optimal Drainage
Drainage is key to keep plants from drowning. Your container should
let excess water out of the bottom, so your plants won't sit in overly
soggy soil and succumb to root rot. There should be one large hole or
several smaller holes located at the base of your container.

You can usually drill holes if the drainage is insufficient, and you
can cover a large hole before adding soil with a coffee filter or
plastic screening to keep the dirt from coming out the bottom. If your
container sits on a hard surface, the hole might plug up. Elevating
your container with pot feet or a pot cart will help your plants drain
with ease.

Selecting the Perfect Container
Choosing a container can be daunting. You can use almost anything for
a garden planter as long as it's big enough, has good drainage, and is
made of food-safe material. But keep in mind that the larger your
container is, the easier it will be to maintain. The more soil a
container can hold, the more moisture it will retain. In general,
don’t bother with containers that are smaller than 12 inches across.
Bigger really is better when it comes to growing vegetables in
containers.

Wooden Containers
Wooden containers look lovely when growing vegetables, and you can
typically find optimal-size containers that aren’t too expensive. Or
you can make your own wooden planter box.

Self-watering Containers
Growing vegetables in self-watering containers works well, too. They
are large, easy to use, and incredibly durable. And they make watering
plants a cinch because all you have to do is keep the water reservoir
full.

Ceramic Containers
You also can use plastic or glazed ceramic containers. You can even
use terra cotta pots, but it's harder to keep your plants moist in
them because the clay sucks the water out of the soil. To help solve
this problem, you can line a terra cotta pot with plastic, use a
plastic pot as a liner, or seal the pot with a stone sealing product.

DIY Containers
For an inexpensive container, use a 5-gallon plastic bucket from the
hardware store. Another alternative is to make an unusual container
from something you have around your house, such as an old laundry
basket or toy bin. As long as it’s big enough and has good drainage,
you can really use anything. You can even grow vegetables in straw
bales.

Choosing Seeds or Seedlings
You can start your veggies from seed or buy seedlings. There are some
significant advantages and disadvantages to each. Planting your own
seeds is much less expensive than buying seedlings. Plus, you can
organically grow hard-to-find varieties.

However, starting seeds isn't for everyone. They need 12 to 16 hours
of light per day and good air circulation to grow up strong. Plus, you
absolutely cannot let the seeds dry out, or they're toast. Conversely,
if you give them too much water, they’ll keel over dead. To avoid
this, you can make a self-watering seed starter.

Vegetables for Container Gardens
When choosing vegetables to plant in containers, look for bush or
small varieties (often referred to as dwarf or compact), and ensure
that your climate has enough growing days for the required time to
mature.

Plants that typically grow well in containers include:
Peas: Put tall supports in the container when planting seedlings.
Water frequently, and keep them fertilized.

Potatoes: Some potatoes need a 120-day growing season, so look for
varieties that mature early.

Tomatoes: Like peas, tomatoes need a support system. Use a rod or
tomato cage to keep your plants upright.

Carrots: Use a container that's double the length your variety will grow.

Radishes: Containers don't have to be that large for this spring vegetable.

Eggplant: When planning which variety to buy, know that many eggplants
are fairly sensitive to cool temperatures (lower than 50 degrees
Fahrenheit).

Summer or zucchini squash and cucumbers: Choose bush varieties rather
than the sprawling vine varieties. One plant can fill a 24-inch pot
quickly, so don't crowd your seeds or seedlings. A trellis in the pot
will supply support for the fruit and allow air to flow around the
plant.

Leafy greens: Spinach and leaf lettuce are among the many greens that
you can snip to eat one day and then snip again a few days later. Keep
the cool-season crops in partial shade.

Peppers: Try traditional bell peppers, or spice it up with hot peppers
that are perfect for homemade salsa.

Plants that don't usually work well in containers include:
Large melons
Corn
Large pumpkins or squash
