Selecting a Container
As a general rule, select as large a container as possible. Small containers dry out more quickly and need daily watering. Self-watering planters designed for urban balconies and patios extend the time between waterings. You’ll want to think about weight (once the pot is filled with wet soil and plant material it’s going to be very heavy). And you may want to think about appearance. What look “goes” with your house and other pots? Even fabric pots are good for growing vegetables. With the colorful Grow Bag line, you can add some whimsy to your vegetable garden.
Most importantly, you’ll need to think about the depth of the container you’ll be growing in. (See the list at right.) Plants with deep root systems will be stunted and unhealthy if they don’t have adequate space.
Remember that the deeper the pot, the larger the reservoir of moist soil and the less often you’ll need to water. The exception is a Self-Watering Planter. In this case, the depth of the planting area can be kept to a minimum because moisture is provided by a water reservoir below the planting area.
Where to Put Your Planter
Most vegetables require six hours of sunlight per day. Salad greens and herbs can usually get by with less. Tomatoes, peppers, beans and other sun-lovers will appreciate as much sun as they can get. If your yard is short on sun, consider putting your plants on caddies or adding casters. That way they can be moved during the day or even later in the season as the angle of the sun changes.
Wind is another factor to consider. Your plants will be happiest in a protected location where the wind doesn’t batter and dry out their foliage. Use the shelter of a building, erect a temporary windbreak made from portable fencing or fabric. Arrange your pots so larger plants shield smaller plants. Clustering potted plants also helps to raise humidity levels, keeping plants more productive.
If you are using a trellis or some other type of support in your container, wind is a special concern. Make sure you have a heavy pot and/or that the trellis is secured to a railing or some other fixed upright.
Soil Do not fill your containers with soil from your garden or bagged topsoil. You should fill the containers with a “soilless” blend that will retain moisture and resist compaction, such as Container Mix. I usually mix in a liberal amount of granular organic fertilizer and a shovel-full or so of compost.
