Growth characteristics and marketing of woody ornamentals prevent crop scheduling common in floriculture crops. However, many tasks in the production of woody ornamentals require coordination with the season and/or physiological state of the species. Since most woody ornamental nurseries produce many species or cultivars, a variety of tasks occur concurrently. This review highlights the major tasks required during production for most species of woody plants. The physiological and environmental factors that dictate or influence scheduling are discussed.

As in many other regions, Ontario’s ornamental greenhouses often produce spring crops in more than one layer by placing one or more rows of HBs above the main crop growing on the greenhouse floor or bench (lower level). Although HB production

The University of Arkansas established a new, replicated, woody ornamental plant evaluation program in 1999. Three sites were used across the state and these sites encompassed the three different USDA Plant Cold Hardiness Zones found in Arkansas, Zones 6, 7 and 8. In the first year, 17 different woody ornamental plants were established in the evaluation. Information obtained from performance in this evaluation will be used in Arkansas Select, a marketing program for customers and nurserymen in the state. Nonpatented and nontrademarked plant material will be made available for propagation purposes. Woody plants will be evaluated for 5 years and herbaceous perennials will be evaluated for 3 years.

Oklahoma floriculture producers, ornamental-horticulture retailers, mass-market retailers, and cut-flower wholesalers were surveyed to compare and contrast the industry in terms of attitudes towards their products and problems. Overall, attitudes of all four segments of the industry were neutral to negative on potted flowering plants, but were positive to neutral on bedding and foliage plants. However, producers were slightly negative concerning the postharvest life of bedding plants. While cut-flower wholesalers had a positive attitude concerning cut flowers, ornamental-horticulture retailers and mass-marketers tended to be neutral to negative. In particular, retailers and mass-marketers believed that cut flowers were too expensive and too short-lived. Floral preservatives were used by 82% of ornamental-horticulture retailers, while only 19% of mass-market retailers used preservatives. All cut-flower wholesalers used preservatives. Capital availability and market demand were the factors most limiting expansion for producers and ornamental-horticulture retailers; whereas mass-market firms listed competition as their most limiting factor.

Automated irrigation scheduling systems are widely used in intensive horticultural production environments, such as greenhouse, container nursery, or field ornamental nurseries. Additionally, many high-value food crops are also irrigated, as are

The ornamental horticulture industry uses a variety of materials as ingredients in growing substrates for many ornamental plants. There are many attributes that make growing substrates effective, including good aeration and drainage, availability at an acceptable price, and chemical attributes conducive for plant growth. In recent years there has been a trend in which more traditional organic components, such as Canadian sphagnum peat, have been partially replaced by an increasing array of waste-product compost. Plant response to increasing quantities of compost in the potting mix, and to different types of compost are variable. This paper reviews some important issues in the utilization of urban waste compost products.
