Nursery (horticulture)
A
nursery is a place where
plants are
propagated and grown to usable size. There are
retail nurseries which sell to the general public,
wholesale nurseries which sell only to other nurseries and to commercial
landscape gardeners, and private nurseries which supply the needs of institutions or private estates. Some retail and wholesale nurseries sell by
mail.
Nurseries grow
annuals,
perennials, and woody plants (
trees and
shrubs). These have a variety of uses: decorative plants for
flower gardening and
landscaping, garden
vegetable plants, and
agricultural plants.
Nurseries often grow plants in a
greenhouse, a building of glass or in plastic tunnels, designed to protect young plants from harsh weather (especially frost), while allowing access to light and ventilation. Modern greenhouses allow automated control of temperature, ventilation and light and semi-automated watering and feeding. Some also have fold-back roofs to allow "hardening-off" of plants without the need for manual transfer to outdoor beds.
Some nurseries specialize in one phase of the process: propagation, growing out, or retail sale; or in one type of plant:
groundcovers, shade plants, fruit trees, or
rock garden plants.
Nurseries remain highly labour-intensive. Although some processes have been mechanised and automated, others have not. It remains highly unlikely that all plants treated in the same way at the same time will arrive at the same condition together, so plant care requires observation, judgement and manual dexterity; selection for sale requires comparison and judgement. A UK nurseryman has estimated that manpower accounts for 70% of his production costs.
Business is highly seasonal, concentrated in spring and autumn. There is no guarantee that there will be demand for the product - this will be affected by temperature, drought, cheaper foreign competition, fashion, etc. A nursery carries these risks and fluctuations.
Annuals are sold in trays (undivided containers with multiple plants), flats (trays with built-in cells), peat pots, or plastic pots. Perennials and woody plants are sold either in pots or bare-root and in a variety of sizes, from
liners to mature trees.
Plants may be propagated by
seeds, but often desirable
cultivars are
propagated asexually by
budding,
grafting,
layering, or other nursery techniques.
