Propagation can be done in the field, orchard, forest, outdoor raised
beds, and in protected culture environments such as greenhouses, polycovered
houses, and tissue culture laboratories. The plant propagation
period is generally a very narrow segment of a plant’s life, ranging from
several weeks for fast-growing herbaceous plants to one to two years for
woody perennials. Following propagation, the rooted cuttings, seedlings
(plugs), layers, or tissue culture produced
plants are transplanted as liner plants.
The liner plants are grown in small pots
and then transplanted into larger containers
or directly transplanted into field production.
In other production systems
plants may be propagated and produced
in the same container or field location
without going through a liner stage.
