  • Find suitable containers with drainage at the bottom: Roma tomatoes grow perfectly in 5-gallon containers or containers that are larger. Pots with a height of at least 14-16 inches and a diameter of about 20-24 inches suit the growth of Roma tomatoes. An extra depth on the container will enable the plant to absorb and utilize water effectively. It also makes it easy for the plants to obtain nutrients found in the soil. The deeper the plant roots grow, the more they grow in height.
  • Plant your Roma tomato: Pinch the bottom leaves from your seedling, dig a small hole and put ¾ of the plant inside the soil. When planting Roma tomatoes in a pot, it is advisable to plant seedlings at a deep level. The correct depth will enable the roots to sprout up to the stem giving the plant-strong support.

The supportive cage should be 6 inches deep in the soil to secure the cage firmly.

When applying fertilizer, use one that has balanced nitrogen, potassium, and phosphorus. Do not use excess nitrogen as it can damage the quality of Roma tomatoes.
