For healthy, aesthetic plants, the soil must serve as a reservoir for water, oxygen, and nutrients. While this sounds very straightforward, providing these three essentials can be quite challenging. This leaflet describes the steps to take to ensure these essentials are met in the proper amounts.
The florists' hydrangea has been an important greenhouse crop for many years. Its popularity and production have both been increasing in the past few years. This leaflet outlines procedures for the greenhouse forcing of dormant, pre-cooled hydrangeas.
Each of us are subjected to stresses and pressures every day in our home, work, and living environment; plants are no different. Unfortunately, there is no "stressless" environment, and there is no totally stress-resistant bedding plant. Each site has its stress level and each plant has its tolerance level. There are steps that can be taken to reduce or avoid stress in the landscape. However, no program can prevent all problems, and the key to successful landscape color using bedding plants is to match the particular site with specific plant species.
Pansies have become the most popular annual for mid-fall to late-spring color in the Southeast. Intensive breeding programs that have selected for unique flower colors, large flower size, greater flower number, and temperature tolerance have led to many new and exciting cultivars to select from for use in the landscape. This leaflet was written to give growers production advice for pansies.
Use of bedding plant color beds continues to increase. A recent indicates that over 15% of the flowering bedding plants produced in this country are utilized by commercial landscapers. However, success with color beds requires planning, proper bed preparation, and an intensive maintenance program--all of which are outlined in this publication.
The use of wildflowers in the landscape has increased since Lady Bird Johnson first promoted them in the late 1960s and early 1970s. Wildflowers were further popularized by the "Meadow in a Can" seed collections that were marketed in the early 1980s. A number of books have been written that describe methods for planning and planting wildflowers, however, few recommendations are available regarding maintenance and long-term weed management. In wildflower plantings, weed management is a complex system that requires knowledge of the specific wildflowers and weeds, environmental conditions, and control methods. Therefore, the objective of this leaflet is to discuss weed management strategies that can be applied to the planning, establishment, maintenance and renovation stages of a naturalized wildflower planting.
Plant growth regulators (PGRs) are chemicals used on a wide range of floricultural crops. This publication was designed to help growers understand how and when to use PGRs in greenhouse floriculture operations.
Proper plant nutrition is essential for successful greenhouse production of floricultural crops. As growers move towards substrates that do not contain mineral soil, micronutrient status of substrates and plants becomes more important. This bulletin outlines the major micronutrient problems that can be encountered in greenhouse production and outlines application treatments to correct micronutrient imbalances.
High pH water and high alkalinity in water can be limiting factors in container production of greenhouse and nursery crops. An understanding of both is needed to accurately treat water with a high pH.
Almost any indoor environment is more pleasant and attractive when living plants are a part of the setting. In apartments, condominiums and single family residences, plants add warmth, personality and year-round beauty. Shopping centers, hotels and resorts take full advantage of the colorful, relaxed atmosphere created by green and flowering plants. Offices, banks and other commercial buildings rely on interior plants to "humanize" the work environment and increase productivity.
There are a number of popular bedding plants used in the landscape today; some deserving the attention they get, others not-so-deserving. This publication offers a chart with some under-utilized bedding plants in North Carolina, including characteristics such as temperature and light preferences.
Many greenhouse-grown floricultural crops tend to grow taller than desired and require height control measures to prevent excessive internodal elongation. This leaflet is designed to introduce commercial growers to the alternatives available for height control and suggest appropriate methods for different situations.
New Guinea impatiens have steadily increased in popularity since their introduction into the United States in 1972. Today's varieties offer a wide range of flower colors as well as variegated foliage types. The versatility of this plant allows for its sale as bedding plants, 4 inch potted plants, and up to 12 inch hanging baskets. This factsheet offers advice on growing impatiens.
Water quality and quantity issues are extremely important in container production of plants. This article addresses both quality and quantity issues for greenhouse and nursery production from a best management practices view.
