Cherry tomatoes are usually used fresh in salads or as a snack. These small tomatoes are only slightly larger than a cherry, earning them their name. Tomatoes prefer warm summer temperatures and plenty of sunshine. If you don't have room for a garden bed or your yard receives too much shade, cherry tomatoes are suitable for growing indoors, especially dwarf varieties such as Tom Thumb and Tiny Tim. They are suitable for containers, and they will produce all summer if you supply them with what they need.
Sow one to two tomato seeds in a 2- to 3-inch-diameter pot filled with moist potting soil. Plant the seeds ¼ inch deep.
Cover the pot with a plastic bag and place it in a warm room to germinate. Remove the plastic bag once sprouts appear, generally within 7 to 14 days after sowing.
Place the seed pots in a warm, sunny window sill and water when the soil surface begins to feel dry, usually every three to five days. Transplant to their permanent pots when they are 3 to 4 inches tall.
Fill a 6- to 8-inch-diameter plant pot with a moist potting mixture. Use a pot that has bottom drainage holes and place it in a drip tray to catch any water.
Plant one tomato seedling per permanent pot. Plant the seedlings at the same depth in their new pot they were at in their seed pots. Water until the excess moisture drips from the bottom of the pot after planting so any air pockets in the soil collapse.
Set the tomato plants in a sunny window sill and water every two to three days to keep the soil moist. Rotate the plant each time you water so that all sides receive equal sunlight.
Water the tomatoes once every two weeks with a soluble fertilizer, following package application instructions.
