There are many ways to plant and care for a vegetable garden. If you need an easy, low-maintenance method, a container vegetable garden is as simple as gardening gets. Containers do not require weeding and plants grown in them are less prone to some soil diseases. Preparation of the containers only takes a short time, and the plants just require minimal care. Make the process even easier by purchasing vegetable seedlings at a nursery or garden center.
Fill 14-inch-diameter or larger planters with a quality potting soil. Choose a soil that contains a slow-release fertilizer so that no additional fertilization is required right away.
Plant a vegetable transplant in each planter, planting the vegetable to the same depth in the planter that it was in its nursery pot. Water the soil until the excess moisture drains from the bottom of the planter immediately after planting.
Place a tomato cage on top the container for any plants requiring support. Tomatoes, peppers and cucumbers all benefit from caging. Anchor the cage to the container with a stake.
Set the planters in an area where they receive at least eight hours of sun a day. Water the planters when they begin to feel dry, usually once a day, but they may require water twice a day during hot periods.
Fertilize the planters once a week starting two months after planting. Use a liquid-soluble, balanced fertilizer, following package instructions for exact application amounts.
Treat any insect problems immediately so they are easy to eradicate. Check the undersides of leaves for signs of insect or damage, then treat with an insecticidal soap or pesticide.
Harvest the vegetables as they ripen. This encourages further fruit set and helps ensure that not all your crops will need major harvesting at once.
