Growing tomato plants in containers offers the gardener an easy way to grow juicy vegetables in a limited-space garden. It enables would-be apartment gardeners a way to enjoy a green plant with ample vegetable production with no gardening plot. The containers grow well on balconies, patios, rooftops and within a greenhouse. Tomatoes flourish in 9-inch pots with drain holes during the growing season. Tender vegetables, tomatoes suffer sensitivity to cold weather. Planting a tomato plant within a container enables the gardener to move the plant and container indoors on nights that dip below acceptable temperatures.
Use synthetic potting soil when planting a tomato plant in a pot. If the potting soil does not contain small beads of water-holding gel then mix some into the potting soil. Follow the directions on the gel bag for mixing with the garden soil.
Mix 1 cup of 6-12-12 garden fertilizer into the potting soil. Wet the garden soil prior to planting the tomato plant to help the fertilizer dissolve.
Fill the container with the potting soil. Make a small hole to place the tomato plant within. Plant the tomato plant at the same level it was planted at in its nursery container. Allow at least 1 inch between the soil surface level and the container rim.
Place soil around the tomato plant's root system. Press the soil down to remove all air pockets from between the soil and the roots.
Water the newly potted tomato plant thoroughly. Allow the water to run freely from the holes of the container. Do not allow the pot to sit in water in a saucer. Remove all pooled water from the base of the container once it runs out of the pot.
