When you buy a tomato seedling and want to plant it in a flowerpot of average size, please note that although it looks small when you buy it, it will become much bigger once it grows. Therefore, it is not advisable to plant too many tomato seedlings in one flowerpot. Just plant them together, otherwise there will be too many. When pouring soil into the flowerpot, put a lot of soil. When putting tomato seedlings in it, dig a little soil first, then fill the soil around the tomatoes after planting, and finally press the soil by hand. The purpose of this is very simple, that is, to fully integrate the soil with the roots of tomato seedlings.
