The heirloom roma tomato is prized for its small, 2 inch to 3 inch long fruit that are primarily used for cooking your favorite soups and sauces. Roma tomato plants are also typically resistant to common tomato diseases like blight, making them ideal for beginner gardeners. Grow your own roma tomato plants from seeds and you'll soon have your own bounty of roma tomatoes for your next dinner dish.
Mark out a plot in your garden where you will plant the roma tomato plants. The area must receive a daily minimum of six hours of direct sunlight.
Prepare the soil. Clear away all surface debris and break up the soil to a depth of 12 inches.
Fertilize the plot. Mix in 2 inches of compost to increase both the soil's nutrient levels and its ability to retain moisture. Optionally, add a standard garden vegetable fertilizer, applied according to the fertilizer's guidelines as potency varies by product.
Plant the roma tomato seeds. Bury each seed approximately 1/2 inch below the soil surface. If you're planting more than one plant, space each seed apart by 4 to 5 inches.
Water the planted roma tomato seeds twice a day or as needed to keep the area moist to a soil depth of 2 to 3 inches. The roma seeds will typically sprout within 2 weeks.
Increase watering once the plants reach a height of 1 inch. Add enough water twice a day to moisten the dirt to a depth of 6 inches. This encourages deep root development.
Add 2 inches of mulch around the base of each roma tomato plant once it reaches a height of 4 inches. This helps to prevent soil moisture loss through evaporation.
Harvest the roma tomato fruit approximately 80 days after the seeds were first sown. The tomatoes are ready for picking when they are 2 inches in length.
