Definition - What does Liner Plant mean?
A liner plant is nothing more than a plant that arrives at a nursery in an immature state, and must be grown for one or more seasons before it can be sold.
MaximumYield explains Liner Plant
“Liner” is the term applied to plants that arrive at nurseries at a young age that cannot be sold as yet, and must be grown for a season or more in order to reach a larger size in order to be sold. A liner plant may be one of a set – liners range from trays including 36 cells all the way to trays holding 288 cells. The most common sizes used in the industry are 50 cells and 72 cells (used by wholesalers).
In most instances, a liner plant will arrive at the nursery as part of a group, and will then be repotted into another container. From this point, it will be grown, and may be repotted or replanted yet again. Note that liner plant can also be applied to trees – the term applies primarily to perennial, ornamental and woody plants. It is not used to apply to annual plants that will only last a single growing season.
Understand that the term liner plant and plug are not interchangeable, even though a plug is a type of liner plant. Instead, a plug is a plant grown within a tray. Liner plants are removed from the tray for further processing. Most plugs cannot be purchased alone, and many retailers require customers to purchase the entire tray. This makes plugs a better option for commercial landscaping companies or those responsible for grounds keeping.
