Container vegetable gardens allow you to grow a bounty of fresh vegetables without the need for traditional in-ground garden beds. Instead of using planters, grow vegetables in bags of soil. This is less expensive than purchasing containers for the plants, and the bags can be laid in areas that receive full sunlight. Nearly any vegetable plant can be successfully grown in a bag of soil if it's planted and cared for correctly.
Lay a 10-pound bag of potting soil or compost flat on the ground with one side facing up. Break up the soil in the bag by kneading it with your hands.
Poke three to five holes in the top with a utility knife. Flip the bag over so these holes are on the bottom, where they provide drainage for excess moisture.
Cut three 2-inch-diameter holes on top the bag. Space the holes at equal distances apart, approximately 3 inches apart for small plants and 6 inches apart for larger plants.
Plant the vegetable seedlings through the holes in the bag at the same depth they were at in their seedling pots. Plant tomato seedlings 1 inch deeper than they are at in their seedling pots.
Water the plants with a starter fertilizer solution, following the application rate on the label. Water until the excess moisture begins draining from the bottom of the bag.
Water daily until the excess moisture drains out the bottom. Water with a fertilizer solution once a week after the plants begin flowering. Start at mid-season for leaf vegetable crops.
