True, but the tomato is a delicate plant. The thing about watering the leaves is very true, if the leaves are watered they get sick, if they are not good seeds, the plant does not thrive and even if it has a lot of care, sometimes the same insects spread diseases.

I have my experience growing and tomatoes are one of the plants that require more care. There are certified seeds that allow you to grow certain tomatoes that will not get sick as much, but those are modified seeds and that is another subject. Tomato growing also depends a lot on the type of climate.
