Young plants typically come in trays, also known as liners, which ensure consistent growth and easy handling. However, some young plants, especially those grown directly in the field at a young plant farm, may be supplied as bare-rooted plants. The difference between a liner and a plug is crucial; liners, often larger, are usually derived from cuttings or tissue culture, while plugs, smaller in size, come from seedlings. This distinction is important when selecting the right young plants for your needs.
