RNGR: A national resource for reforestation, restoration, and nursery professionals

Publications Posted on: November 17, 2011
The Forest Service developed the national Reforestation, Nurseries, and Genetics Resources (RNGR) program to provide expert support to State, industrial, and private forest and conservation nurseries throughout the country. The RNGR program includes technical assistance to nurseries, research projects (to address seedling and field issues), and Internet sites.

Discovering ways to improve crop production and plant quality [Chapter 17]

Publications Posted on: June 24, 2009
Working with plants is a process of discovery. Being curious and aware, paying close attention, and staying open and adaptive are important practices. Books and people can help us learn about plants in the nursery, but the very best teachers are the plants themselves. "Research" is simply paying close attention, tracking what is happening and what is causing it to happen, asking questions, and seeking answers.

Nursery management [Chapter 16]

Publications Posted on: June 24, 2009
This handbook provides an overview of the factors that go into starting and operating a native plant nursery. Management includes all aspects of working with plants in all their phases of growth as described in Chapter 3, Crop Planning and Developing Propagation Protocols.

Holistic pest management [Chapter 15]

Publications Posted on: June 24, 2009
As any experienced grower knows only too well, nursery management is a continuous process of solving problems. Murphy's Law of "anything that can go wrong, will go wrong" sounds as if it were meant for native plant production. One recurring problem is pests. Nursery managers have traditionally talked about "controlling" a pest.

Beneficial microorganisms [Chapter 14]

Publications Posted on: June 24, 2009
The web of life depends on microorganisms, a vast network of small and unseen allies that permeate the soil, water, and air of our planet. For people who work with plants, the greatest interest in microorganisms is in the complex communities that are part of the soil.

Harvesting, storing, and shipping [Chapter 13]

Publications Posted on: June 24, 2009
Plants are ready for harvest and delivery to clients after they have reached target specifications (see Chapter 2, The Target Plant Concept) and have been properly hardened (see Chapter 12, Hardening). Originally, nursery stock was grown in soil in fields; nursery managers would "lift" those seedlings out of the ground to harvest them.

Hardening [Chapter 12]

Publications Posted on: June 24, 2009
To promote survival and growth following outplanting, nursery stock must undergo proper hardening. Without proper hardening, plants do not store well over winter and are likely to grow poorly or die on the outplanting site. It is important to understand that native plant nurseries are different from traditional horticultural systems in that native plants must endure an outplanting environment in which little or no aftercare is provided.

Fertilization [Chapter 11]

Publications Posted on: June 24, 2009
Fertilization is one of the most critical components of producing high-quality nursery stock. Seedlings rapidly deplete mineral nutrients stored within seeds, and cuttings have limited nutrient reserves. Therefore, to achieve desired growth rates, nursery plants must rely on root uptake of nutrients from the growing medium.

Water quality and irrigation [Chapter 10]

Publications Posted on: June 24, 2009
Water is the single most important biological factor affecting plant growth and health. Water is essential for almost every plant process: photosynthesis, nutrient transport, and cell expansion and development. In fact, 80 to 90 percent of a seedling's weight is made up of water. Therefore, irrigation management is the most critical aspect of nursery operations.

Vegetative propagation [Chapter 9]

Publications Posted on: June 24, 2009
For the past 30 years, interest in the propagation of native plants has been growing. Many desirable and ecologically important species, however, are difficult or very time consuming to propagate by seeds. Thus, nursery growers may want to investigate how to propagate a species of interest by vegetative propagation.
