Choosing Containers

Happily, most vegetables aren't fussy about what kind of container they grow in. The only basic requirements is that the container is large enough to hold the plant and that it has drainage holes so excess water can escape.

When it comes to size, the bigger the pot is, the better, especially for beginners. The reason for this is that large pots hold more soil -- and thus, hold moisture longer so you don't have to water as much.

Look for containers that are at least 10 inches wide and 12 inches deep. Large flowerpots, half barrels, plastic-lined bushel baskets, window boxes, planters, and large containers (like 5-gallon buckets) work just fine.

Some vegetables need particularly large containers. Standard-size tomatoes and vining crops, such as cucumbers, will do best for you in containers 20 inches or more across. Peppers like pots at least 16 inches in diameter. In a pinch, most will still grow in a 5-gallon or larger container.

If your container does not have drainage holes, you will need to add several. Use a 1/4-inch drill bit to create holes in the bottom or along the sides near the bottom. Line the bottom of the pot with screen or landscape cloth to prevent soil from spilling out of the holes.

Plants that grow tall or produce vines -- like tomatoes and cucumbers -- will be more productive if grown up a support. A wire cage, inserted into the container at planting time, will do. Use larger, heavier containers for trellised plants to minimize the risk of tipping.

Not sure what type of container to grow your vegetables in? Don't fret -- typically, you'll care more about this than your plants will.

In general, plants in terra-cotta (clay) need more attention to watering than other types of pots, because of the porous nature of the terra cotta.

Also think about the color. Dark colors absorb heat -- so they may make the soil too warm for some vegetable crops in summer, especially in hot-summer areas.

And avoid containers made of treated wood, as it may contain chemical compounds that could be absorbed by your vegetables.
