Specifically bred for use in hanging baskets, Tumbling Tom tomatoes grow in cascading branches that contain 2-inch, cherry-size, oval-shaped sweet fruits. This heavy yielding variety produces early at 65 days after transplanting. If choosing to plant seeds directly in the ground, you will sacrifice overall harvesting time. Start seeds indoors for the best results and to take advantage of the growing season.
Saturate your seed-starting mix with water. Let it sit in a sink or bucket overnight to properly absorb the water. Do not work with a dry mix.
Fill the planting cell with the seed-starting mix once the mix feels damp, not soggy.
Push one to two Tumbling Tom tomato seeds down into the middle of the soil 1/4-inch deep. Place the soil back over the top of the seeds. Do not sow seeds until five to six weeks before the last expected frost.
Set the planting cell in a warm location for germination, a place that maintains a 70 to 80 degree Fahrenheit temperature. Use a heating mat, available from garden centers, to keep a consistently warm environment. After germination and the Tumbling Tom seedlings start to emerge, place the cell in a window that receives full sunlight or under grow lights. Occasionally turn the plant so that all sides receive adequate light.
Trim the weaker seedlings from the plant when they develop leaves. Cut all weaker seedlings at soil level with a pair of clean scissors, leaving only one seedling.
Water daily with a gentle stream of water. Soil should appear moist.
Plant Tumbling Tom seedlings outdoors when night temperatures consistently stay above 55 degrees. Space the plants 6 inches apart. If planting in a hanging basket, plant one per 12- to 15-inch basket.
