1. Location, location
Vegetables need 6 to 8 hours of sun per day. For heat-loving plants, a south or southwest exposure is best. To keep lettuces productive in the summer, a southeastern exposure gives them light early in the day and keeps them out of the strong afternoon sun. Of course if your container small enough to carry, you can move from place to place, as necessary.
2. Choosing a container
Somewhere out there in the marketplace, there's the perfect container for you in the material, shape, size, and price range you seek. Ceramic, plastic, terra-cotta, wood...the list goes on. You can purchase a container that’s diminutive, or you can get one that requires a forklift to move. You can even get a railing planter with a bottom that’s configured to sit snugly on a 2x4 or 2x6 deck railing. Or you can simply reuse something you already have, such as a whiskey planter, garbage can, joint-compound bucket, baskets, or windowbox.
3. Soil selection is critical
A high-quality potting soil is your best bet, and Reelick recommends Hamptons Estate Professional Potting Soil. Another good choice is a commercial soil-less mix. Topsoil alone is too heavy and should be avoided. And it never hurts to add some compost. To retain moisture, Reelick suggests adding some Soil Moist to the bottom of the container to help retain moisture.
4. Plant from seed or seedlings
Either will work. Nearly any vegetable can be grown in containers (Reelick wouldn’t suggest trying corn, pumpkins or watermelon), but it’s best avoid “mammoth” varieties. Stick with “patio” tomatoes, Asian-style eggplants (long and skinny), and bush squash. Anything tall will need a trellis or stake and a deep container.
For seeds, make a shallow depression in the soil, sprinkle in some seeds, cover lightly with sand, and water. For seedlings, plant and water. Be prepared to thin when the seeds sprout.
5. Water and fertilize
If your containers dry out completely, your plants are toast. Soak the containers before they reach that condition. Self-watering containers are sold by Gardener’s Supply and many other garden sites. For fertilizing containers, Reelick swears by Osmocote and Jack’s Classic Plant Food.
6. Don’t forget to harvest
When the food is ready, don’t let it go to waste. Pick leafy lettuce by the leaf, and the plant will grow more. When the radishes are pulled, you can plant something else.
7. In the fall, put your container garden to bed
Each year you’ll want to put a fresh soil mix into your containers, so you need to empty them before spring rolls around. With ceramic containers, it’s important to do this in the fall if you live in a cold climate, or the containers may crack.
