Container gardening provides those people who lack the ability to plant a garden, the same joy of growing things and producing their own fresh vegetables. A mixed vegetable container garden growing on the patio allows you to have vine ripened tomatoes, fresh lettuce, crisp radishes, and juicy peppers ready for tossing a salad at a moment's notice. As you become more experienced with container gardening, different vegetable combinations can be used in the growing container.
Position the container where it will receive the best sunlight. As the mixed vegetable container garden is planted and starts growing, the weight may limit mobility. Choose the final growing place prior to planting so there is no lifting involved after planting.
Fill the container with the soil almost to the top. As the season progresses, the dirt will settle. Tomatoes and other plants need plenty of soil to allow their roots to spread out and develop fully, so the pot needs to be at least 12 inches deep.
Push the garden stake into the planter as far down as it will go. As the tomato plant grows, this stake will be used for support. It needs to be deep enough that strong winds or heavy vines do not topple the stake or the plant over during the growing season.
Plant the tomato starter plant next to the stake, on one side of the container and the pepper plant on the other side of the container. Plant the radish seeds about 2 inches apart between the two plants. There may only be room for 6 seeds but radishes grow quickly and as the season progresses they can be replanted for another harvest. Plant the lettuce seeds along the outer edge of the planter. The lettuce should barely be covered with the soil. Again, there may be only room for a few seeds, but as leaf lettuce grows and is harvested quickly, it will keep producing throughout the year.
Water the mixed vegetable container garden thoroughly. Keep the soil moist by misting every other day until the plants are established and the seeds start to germinate. You will need to water at least twice a week after the plants have sprouted. Turn the planter occasionally for even distribution of the sunlight. During the warmer part of the growing season, check the soil for dryness and water daily, if necessary for the peppers and tomatoes to develop properly. Inconsistent watering may cause the tomatoes to develop blossom end rot, making the fruit unsuitable for harvest.
