Seedlings should be transplanted to larger containers within a few weeks after germination. Leaving seedlings in the germination container until they begin to crowd each other will result in poor quality transplants.

When moving the seedlings, gently grasp the transplants by a leaf (not the stem). As you lift the plant, gently loosen the soil beneath the plant with a dibble, popsicle stick, or pencil. This will ensure you take the maximum number of roots with the plant to the new pot. The growing medium used for transplants should have the same characteristics as the germination medium. A variety of containers may be used for transplants. Containers should be large enough to allow small plants to grow indoors until ready to be transplanted to the garden. Square pots, cells (1 x 1 inch, 1.5 x 1.5 inch), or 2 to 3-inch round containers are satisfactory. Containers should have holes in the bottom for drainage and water uptake.

Transplants should also receive a maximum amount of available light for best growth. "Stretching" of transplants (weak, spindly growth) indicates they are not receiving enough light.
