Imagine enjoying fresh vegetables and blooming flowers year-round, regardless of whether there's snow or scorching heat outside. This isn't a distant fantasy but the reality made possible by greenhouse nursery operations. Today, we explore Oregon - America's premier nursery production region and its remarkable green revolution.
A nursery serves as a specialized facility for cultivating trees and plants until they're robust enough for transplantation. These operations may occur outdoors or indoors, with greenhouse structures enabling controlled indoor cultivation.
These temperature-regulated structures function as massive glass enclosures, providing stable, warm environments where growers can precisely control temperature, humidity, light exposure, and other growth factors - effectively eliminating seasonal limitations.
In 2020, Oregon's greenhouse nursery industry claimed the top position among the state's agricultural commodities by value, generating significant economic impact and supporting over 22,000 jobs.
The industry traces back to 19th century pioneers traveling the Oregon Trail. Henderson Luelling, a notable settler, began cultivating nursery trees and shrubs in 1847 - twelve years before Oregon achieved statehood. Partnering with neighbor William Meek, they established the Pacific Coast's first grafted plant nursery, eventually cultivating 60+ plant varieties and laying Oregon's horticultural foundation.
The state's abundant forests feature two primary nursery crops:
Growers employ distinct techniques based on plant requirements:
Greenhouses and nurseries nurture various plants to transplant-ready maturity, including lettuce, carrots, and culinary herbs - all with unique growth requirements.
While controlled environments optimize growth, they also risk fungal and bacterial outbreaks. Common threats include:
Nurseries supply plants at various growth stages through retail (consumer-focused) and wholesale (landscaper/garden center) channels, while hobbyists maintain private collections.
