Transplanting and Potting up Seedlings

August 20, 2018

You may have multiple stages of transplanting before your plant reaches its final pot. Once the roots of your seedlings or cuttings have grown to the edges of their seed plug or pot and have sprouted three or more true leaves, it is time to bump them up to larger containers. True leaves look like mature leaves.

A small lettuce in a seed plug is rooted and ready to bump up into a 4-inch pot. After the plant roots fill the new pot, you can move it to a 1-gallon container for its long-term home.

Once the roots system has filled in to reach the edges of the pot and is extensive enough to hold together most of the soil in the pot, your transplant is ready to be planted into your outdoor garden (if temperatures are right) or moved into a larger container for continued growth indoors.
