Even if your gardening space is limited to container plants, you can still harvest fresh vegetables. Almost any vegetable you can grow in the ground, you can grow in a container.
Finding the Right Containers
Many kinds of containers can be used for growing vegetables. Because large decorative pots can get expensive, look for an economical alternative. Here are a couple of suggestions to get you started:Restaurants are often glad to give you barrels and buckets that can be turned into planters.Home stores also carry a huge assortment of inexpensive plastic buckets and containers to choose from. Heavy-duty rubber containers meant for storage are rugged and long lastin
To make containers suitable for vegetable gardening, drill drainage holes in the bottom. For a 10- or 15-gallon container, use a 1″-diameter drill bit on a variable-speed drill to create five holes. Drill each hole using light pressure at a medium speed. For the smaller buckets, use a 1/2″-diameter drill bit and make three drainage holes per bucket. As a general rule, drill one drainage hole per one to two gallons of soil that a container will hold. Vegetables need adequate drainage to grow, so you’re better off having more holes than you need than not enough.
When you arrange containers on your patio or deck, put the inexpensive ones at the back of the patio where they won’t be seen. In the front, place an assortment of attractive pots and containers. Consider using a mix of plain and glazed terra-cotta pots.Basic terra-cotta pots are fairly inexpensive and can be found in almost any shape and size. They have classic good looks and work well in almost any setting. The only downside to them is that they can crack in cold-weather climates when the porous clay absorbs water and then freezes.
To prevent cracking, you can water-seal the inside of a terra-cotta pot. Joe used a masonry waterproofing sealer and brushed it on the inside of the container. As soon as it dries, the pot will be waterproof. As an added bonus, water-sealed pots don’t dry out as quickly as unsealed pots and will need to be watered less often.
Once the larger containers are filled with potting soil and have been watered, they will be heavy, probably 50 or 60 pounds or more. Since you want to be able to move them around, place a set of casters under each of the largest containers before you plant them. Those that won’t be moved should be elevated from the patio with two or three bricks, to improve air circulation and drainage.
