Liners

"Liners" is a horticultural term referring to very young plants, usually grown for sale to retailers or wholesalers, who then grow them to a larger size before selling them to consumers.

They are grown in plastic trays with many "cells," each of which contains a single liner plant.

[3] A liner traditionally refers to lining out nursery stock in a field row.

The term has evolved to mean a small plant produced from a rooted cutting, seedling, plug, or tissue culture plantlet.

Seedlings and rooted cuttings can also be transplanted into small liner pots and allowed to become established during liner production, before being transplanted to larger containers (upcanned) or outplanted into the field.
