Choose any type of container for planting---bucket, pot, hanging basket or planter---as long as it has drainage holes in the bottom. Consider the types of materials containers are made of and their impact on watering; for example, a plastic pot will require less watering than a clay pot.
Use regular potting soil for smaller pots and hanging baskets. Use a soil-less, lighter-weight mix for larger containers. Make sure the soil is well drained and rich in organic matter. Amend the soil by adding a slow release fertilizer, mixed according to the manufacturer's instructions. Avoid using garden soil as it may be infested with garden pests.
Start tomato seeds indoors in early April or buy already started plants in May. Purchase varieties that will grow well in containers. Consider the Florida Basket, Micro Tom or Anmore Dewdrop for hanging baskets. Plant Tiny Tim, Totem or Yellow Pygmy in small pots.
Place a tomato stake or cage in the container. (Hanging baskets do not need cages.) Add soil mix to the container, filling it three-fourths full. Place the plant near the stake and add soil mix around the plant. Water the plant thoroughly. Put the container in an area where it will receive six to eight hours of sunlight. Fertilize the plant once a week with a soluble fertilizer with a 15-30-15 ratio.
