Liner Production and Designations Commercial Plant Production
An Overview of Nursery Crop Production
Liners Small “starter” plants produced using various methods of plant propagation. Potted Bare-root Age and size vary Sold by caliper, height, container size and sometimes age.
Liner Production-Direct Stick SWC into Small Containers
Liner Production-SWC stuck in Sand
Liner Production- Arrowwood Viburnum SWC Stuck in Sand
Liner Production- Seedlings
Liner Production- Grafting
Other Liner Examples Potted shrub liners
Lining-Out: Shrub Liners to Field Spacing
Lining-Out: Liner to Large Container
Small Plant Culture After liners are removed from propagation they may be transplanted to small plant culture for one to several years. Objectives: Protection Provide optimal conditions for rapid, vigorous growth Can occur in the field or in containers. Many nurseries skip small plant culture.
Field Spacing for Rows or Beds 6 – 12 inches between rows. 4 – 10 inches between plants in a row.
Small Plant Culture in Containers 4 inch container #1 container
Bottom Line Small Plant Culture Small liners go in Bigger liners come out
Transplanting The process of moving a plant from one production area to another production area. Transplanted from propagation to small plant culture. Transplanted from small plant culture to the production field. At some point in the production process plants are transplanted to their “final spacing” and will stay at that spacing until harvested. Tops and roots pruned.
Liner Designations The American Standard for Nursery Stock provides guidelines for liner designations. Provide for a common understanding of the liner products available to the industry.
Liner Types Based on Propagation Method C = cutting U = un-rooted cutting G = grafted L = layered S = seedling M = micro-propagated or tissue culture D = division
Micro-propagated Ash Trees
Small Plant Culture R = root pruned P = pot or container grown T = transplanted to a row in the field B = transplanted to a bed O = not transplanted
Nursery Bed vs. Field Rows
Nursery Beds Bed forming implement Beds
