Two tomato seedlings can be separated without hurting them once they have their first pair of true leaves. Dig the plants out of their seed-starting flat with a craft stick or a spoon. Gently separate the roots and stems so that the tender stem isn't bent or damaged. Plant the seedlings in separate peat pots or containers. Water the plants immediately after transplanting them to prevent wilting.
