Here are some more vegetables to grow in containers.
Growing Tips: Growing eggplant in containers offers several advantages. Eggplants require warm temperatures, even at night, and planting in a dark container will concentrate and hold heat. You can also move the container to wherever the sun is or place it on a hard surface that radiates heat. Another big plus is that growing them in containers helps to control some common pests, like wireworms.
Once the plants start bearing fruits, they will get top heavy. Some staking may be required, to prevent the branches from drooping. They can also tip over, if the diameter of the container is not large enough to balance them. The slender varieties tend to produce more fruits and can be picked while young, short and tender. Some of the newer varieties, like 'Hanzel' and 'Little Fingers', are ready to harvest at 3 inches and they grow in cluster, so they produce more fruits.
Minimum Container Size: 4 - 5 gallons, at least 8 inches deep.
Spacing: 1 plant per container
Approximate Yield: Slender varieties - 10 - 12. Larger varieties - 4 - 8.b
Recommended Varieties: Slender - 'Bambino,' 'Hanzel,' 'Little Fingers,' 'Ping Tung.' Classic - 'Black Beauty,' 'Rosa Bianca
Growing Tips: Full sized onions not only take up space, they also require a long time in the ground. Green or bunching onions can be slipped into pots with other vegetables or grown on their own. Either way, you can snip what you need and leave the plants to grow more leaves. To grow green or bunching onions to full size, you will need to thin the plants to 2 - 3 inches apart, but you can eat all the plants you thin out. And even though they are not forming large bulbs, they still need plenty of water. The soil can be kept consistently moist, but not dripping wet. Start your first plants in early spring and keep succession planting into summer.
Minimum Container Size: 6 inches deep.
Spacing: 2 - 3 inches. Approximate Yield: You can harvest green leaves and leave the whole plant or slice off the entire plant.
Recommended Varieties: 'Beltsville Bunching,' 'Crysal Wax,' 'Evergreen Bunching.'
Growing Tips: Lettuce loves containers. You can move it into sun or shade, as needed, lift it away from pests and animals and keep it handy for cutting. If you grow loose leaf varieties and cut only the outer leaves, the plants will continue to grow for months. However sooner or later they will tire out, so keep planting seed every 3--4 weeks for a succession of harvests.
Lettuce does best in cool weather, but containers can be moved to a shady location and grown all summer or moved to a protected location and grown into late fall and winter. Water is essential to keep lettuce happy. Lack of water will cause lettuce plants to bolt.
Minimum Container Size: 6 inches deep and any width or diameter.
Spacing: Leaf lettuce seed can be seeded closely and thinned - and eaten - as you like. if you would like your plants to form heads, thin to 8 inches between plants.
Approximate Yield: 20+ leaves or 1 head.
Recommended Varieties: 'Buttercrunch,' red or green 'Salad Bowl' and any variety bibb.
