Soil: warm, well-drained, soil rich in organic content. They can tolerate slightly acidic soil but will be most productive at pH levels between 6.0 and 6.5.
Sun: The Roma tomato requires full sun for maximum productivity. Ensure your tomatoes get at least 6 hours of direct sunlight every day.
Temperature: Roma tomatoes grow best between 55℉ and 90℉. Don’t start your tomatoes too early in the season, they are highly susceptible to frost.
Water: Growing Roma tomatoes need plenty of water, especially when fruiting. Inconsistent or inadequate water may lead to split tomatoes.
But be careful not to overwater your tomatoes, especially in colder climates.
Fertilizer: Tomatoes are heavy feeders. Incorporate a balanced, slow-releasing fertilizer when planting. You can also add in some compost or manure throughout the season.
Alternatively, you can use a liquid fertilizer every 2 to 3 weeks. But avoid high nitrogen fertilizers. They encourage foliage growth but affect fruit quality in tomato Roma.
Also, don’t use any fertilizers containing weed killers. They may end up killing your tomatoes as well.
Pruning: Since Roma tomatoes are a bush variety, they don’t need pruning. Instead, you should trim around the plant to get rid of any unwanted or damaged parts. But remember, too much trimming can lead to reduced yields.
Weeding: Cultivate lightly with a garden hoe or spade to get rid of young weed before they become a problem. Be sure to dig just deep enough to cut off the weeds below the soil surface. But not so deep you damage your tomatoes’ roots.
You can also mulch with herbicide-free grass clippings or straw. Mulch helps reduce weed growth and also promotes moisture retention in the soil.
