If growing your own vegetables and herbs sounds appealing but you don’t have a lot of space, containers are a viable alternative to the traditional kitchen plot. All you need is a balcony, patio, deck, or other small space that gets at least 6 hours of direct sun. The reasons to grow your own food in containers are many:

  • Home-grown produce tastes better than store-bought and is often more nutritious.
  • Containerized vegetables are more accessible, usually grown right on your doorstep.
  • Some vegetables do better in containers, while some won’t perform well at all.

By choosing the right vegetable varieties and following some basic tips, you can be well on your way to growing and harvesting your own farm-fresh food at home.

STARTING YOUR CONTAINER VEGETABLE GARDEN

Evaluate your site:

  • Make sure your site receives adequate light by observing how the sun moves throughout the day.
  • In hotter climates, plants may need afternoon shade so they don’t overheat.
  • Measure the space to make sure there’s enough room for the containers that you’ll need.
  • To maximizet to g the use of your space, include plants that grow vertically such as peas, pole beans and cucumbers.
  • Make sure there’s a convenient source of water close by.

Make a plan:

Draw up a quick sketch to calculate how many containers you’ll need, and in what sizes. Make a list of supplies, including containers, soil, garden tools, seeds, plants, watering supplies, fertilizer, and plant supports such as trellises and cages.

Choose wharow:

Make a wish list of what you’d like to grow, focusing on what you are most likely to eat. Limit to what you have time and space for and include easier varieties such as lettuce and radish to maximize your success.
(Tip: When looking at catalogs, online sources, and plant labels, look for descriptive words such as dwarf, compact, patio, bush, and space saver, which indicates smaller varieties more suited to containers.)

Seed vs. starts:

Quick growers such as lettuce, bush beans, and peas are easy to grow from seed. Plants that take longer to mature such as tomatoes, peppers, and eggplant are best grown from nursery starts.

Choose containers:

Almost anything can act as a container providing it’s big enough, has good drainage, and is made from food-safe material. Here are some tips for choosing containers:

  • Leafy greens, radishes, and other shallow-rooted vegetables need less space than plants with deeper roots such as tomatoes and peppers.
  • Large pots are better, as they won’t dry out as quickly and have plenty of room for root development.
  • Choose containers that are at least 12 inches tall and deep, such as 5-gallon size or larger plastic pots, wooden planter boxes, or half whiskey barrels.
  • Avoid terra cotta or clay pots, which dry out quickly, as they allow water to evaporate through the walls of the pot.
  • Also avoid metal and dark colored containers (such as black plastic nursery pots), which can become too hot, causing roots to become overheated.

Can vegetables be grown in self-watering containers? Yes, vegetables also perform well in self-watering containers. All you need to do is remember to keep the water reservoir full.

CONTAINER VEGETABLE GARDENING BASICS

Light:

Most vegetables require at least 6 to 8 hours of full sun per day, while some varieties such as lettuce are more shade tolerant.

Temperature:

Research temperature requirements for each vegetable before planting.

  • Cool weather plants such as greens and peas can be planted earlier in the season. Soil temperature should be at least 40 to 50 degrees F. Others such as carrots and potatoes can be planted in mid spring.
  • Warm weather varieties such as peppers and tomatoes should wait to be planted until late spring when soil temperature is at least 70 degrees F.

Water:

Vegetables need consistent moisture. Containers dry out more quickly than plants in the ground, so need to be watered more often. As a general rule, water 2 to 3 times a week during summer and daily during hot spells. Sun exposure, humidity, and container size factor into how fast the soil dries out. If soil feels dry an inch or two below the surface, then it’s time to water. Using a drip irrigation system can help maintain consistent watering.

Soil:

Use a high-quality, organic potting mix, filling the container to an inch or two below the rim. Soil will settle over the growing season. Don’t use garden topsoil, as it can become compacted, resulting in poor drainage and root rot.

Fertilizers and amendments:

Most vegetables are heavy feeders. Fertilizers leach out quickly from containers due to frequent watering, so proper fertilizing is crucial to productivity. At the time of planting, add a slow-release organic granular fertilizer and mulch with compost or manure. Supplement with water soluble fish emulsion, seaweed fertilizer or compost tea every two weeks.

EGGPLANT

Best grown from starts, eggplant often performs better in pots than in the ground. Allow one plant per square foot and provide a trellis or tomato cage to keep plants from tipping over from the weight of the fruit.

Varieties to try: Choose compact or mini varieties such as ‘Bambino’, ‘Fairy Tale’, ‘Little Fingers’, or ‘Patio Baby’.

PEAS

Start these cool weather plants from seed in early spring or late summer and provide vertical support such as a bamboo teepee at the time of planting. These legumes fix nitrogen into the soil, providing a nutrient-rich environment for the next crop. Once they’re finished producing in late spring, replace with warm weather vegetables such as cucumber or eggplant.

Varieties to try: Grow dwarf or bush types such as ‘Snowbird’, ‘Little Marvel’, ‘Little Crunch’, or ‘Oregon Sugar Pod’.

POTATOES

Containers offer a cleaner growing environment, helping to protect against diseases such as potato blight. A deep plastic bucket or grow bag is an easy solution for small spaces.

Varieties to try: Try unusual heirloom varieties you can’t buy in the store such as ‘Adirondack Blue’, ‘German Butterball’, or ‘Russian Banana’, or stick to reliable favorites such as ‘Red Pontiac’ and ‘Yukon Gold’.
