Q.My Roma Tomatoes Are Not Growing Big
I am growing Roma Tomatoes in a garden box and have been watering them since it’s getting pretty hot here in NC. But they are growing very small. One was ripe but looked like a golf ball size cherry tomato before it started to rot. Do I need to add more fertilizer within the soil than what I used?
Water is very much a part of tomato success, but good rich soil, adequate container size, full sunshine, a good organic fertilizer are all important. Don't over fertilize, this will cause all plant and no fruit. Follow package instructions.
I have great success adding Epsom Salt to all my tomato plants as soon as they are blossoming.
I would add about 1/8 cup sprinkled around the base of the plant and watered in each week.
