Baby tomatoes, also known as cherry tomatoes, grow in much the same way as standard-size tomatoes. Yet, these plants have a larger yield of fruit than their larger tomato-producing cousins. Expect to harvest hundreds of baby tomatoes from a single plant through the first frost of your growing season. This plant is easy to grow and requires minimal care. It can grow to a height of 5 to 6 feet with a spread of 2 to 3 feet. Choose your planting site accordingly.
Choose a growing site in full sun.
Use a garden spade and prepare the site by loosening the soil to a depth of 6 inches and a width of 12 inches.
Amend the soil by adding a 2-inch layer of compost. Work the compost into the loose soil thoroughly by hand or with a garden spade.
Dig a hole in the prepared soil. The hole should be deep enough to cover the seedling up to its first set of leaves.
Place the seedling into the hole and refill the hole with soil. Gently tamp down around the plant to remove any air pockets.
Water generously. After the water has absorbed, add more soil to the site if the soil has shifted below ground level. Plan to keep the growing soil moist, but not wet. If the ground around your plant is dry, add water. If your plant wilts, it needs more water than is being provided.
Use a tomato cage or a stake to support the plant as it grows. If you opt for a cage, place it down over the plant. If you opt for a stake, place it three or four inches away from the stem of the plant. Wrap a string around the plant's stem and the stake at two different points.
Fertilize your baby tomato plant with a liquid plant fertilizer every three weeks during the growing season.
Harvest your baby tomatoes when they are completely red and glossy. Pick them from the plant gently to avoid damaging the plant.
