When should tomato seedlings be repotted into larger containers? When tomato seedlings have reached a height of at least 3 inches and have their first true leaves, also known as the second and subsequent sets of leaves that develop, they are ready to be transferred into their permanent homes.
Do I need to separate tomato seedlings?
When tomato seedlings are at least 3 inches tall and have 4-6 genuine leaves, you should carefully separate them from one another while attempting to preserve as much of the roots as possible. Because the stems of younger tomato seedlings are more susceptible to breaking, dividing them can be fatal. On the other hand, splitting much bigger and more mature plants might cause root damage.
Do tomato plants need repotting?
When they are large enough, tomato seedlings can be transferred from their starter containers into the outdoors. When you repot a tomato seedling, also known as when you move it into a larger pot, you do the initial transplanting, which is completely optional.
