  • Height Management of Ornamentals

    MSU Extension’s floriculture educational and applied research programs help improve greenhouse crop production and business management by providing trusted information on new production techniques and management strategies.


  • Florel on summer production of pansy

    Published on April 18, 2004
    We performed experiments to determine if ethephon (e.g., Florel) could be used to delay flowering of pansy and viola when grown under bright, warm and long-day conditions.

  • Tips on using uniconazole

    Published on April 18, 2011
    This article provides suggestions for how and when to use uniconazole (e.g., Sumagic and Concise) as a spray or drench to obtain desirable, more compact ornamental plants.

  • PGR rates and timing for plug production

    Published on November 18, 2003
    Application rates and timing of the plant growth regulator Bonzi (active ingredient: paclobutrazol) was put to the test in this Michigan State University research on seedling plugs of bedding plants.

  • The PGR ancymidol

    Published on February 17, 2015
    Plant growth retardants (PGRs) that contain the active ingredient ancymidol aren’t as commonly used in floriculture as most other PGRs, but there are some potential upsides that merit consideration.

  • Using ABA to reduce water loss

    Published on August 18, 2011
    Michigan State researchers investigated how an experimental formulation of abscisic acid (ABA) influenced drought stress tolerance of finished potted garden chrysanthemums and aster. The product mentioned is not commercially available.

  • Increasing plant height

    Published on October 17, 2014
    There are numerous ways to promote extension growth, including changes to plant culture or the growing environment, or applying a plant growth regulator that includes gibberellic acid.

  • Do it yourself (conduct your own trials)

    Published on May 18, 2010
    Many articles often recommend that growers perform their own smal-scale tests for the specified procedures. Here are a few tips for conducting your own experiments.

  • Ethephon drenches on bedding plants

    Published on April 18, 2013
    In the second of a two-part series with ethephon (e.g., Florel), we shows that drenches are a viable method to control height and size of several bedding plant crops.

  • Plug / liner dip guidelines

    Published on February 18, 2013
    A plug or liner dip is a plant growth retardant (PGR) application technique for ornamentals in which a tray of finished young plants is placed into a shallow PGR solution for a short period of time.

  • Non-chemical height control techniques

    Published on May 18, 2013
    There are several environmental and cultural practices that can produce shorter plants, but strategies must be implemented over a period of time to achieve desired outcomes.

  • Successful use of the PGR daminozide

    Published on August 18, 2013
    The plant growth regulator (PGR) daminozide is used as a foliar spray primarily to inhibit extension growth of ornamental crops.

  • A new paclobutrazol (Piccolo 10XC)

    Published on September 18, 2011
    Fine Americas released a new, more concentrated formulation of paclobutrazol called Piccolo10XC. Plant responses were similar when the same active ingredient, volume, and application rate were used.

  • Using chlormequat chloride with success

    Published on April 18, 2014
    Chlormequat chloride is a plant growth retardant used to promote flowering or inhibit extension growth of floriculture crops grown in greenhouses, shadehouses and container nurseries.

  • Brushing plants for height control

    Published on February 18, 2009
    “Brushing” plants is proving to be a promising, albeit unconventional, height control technique. When touched or moved, plants release ethylene, which can inhibit elongation.

  • PGR application considerations

    Published on May 18, 2013
    This article briefly presents some of the considerations when selecting which plant growth regulator (PGR) rate, method and active ingredient to apply to greenhouse-grown ornamental crops.

  • Fascination on poinsettia

    Published on September 12, 2005
    Did you hit your poinsettias with too much growth retardant? This Michigan State University research shows how to recover using products that contain gibberellic acid.

  • Using a GA to increase plant height

    Published on August 8, 2018
    Regardless of the cause, the most common technique to increase plant height of containerized flowering plants is an application of gibberellic acid (GA) by someone certified as a pesticide applicator.

  • Graphical tracking

    Published on July 18, 2007
    Graphical tracking, a decision-support tool, can help growers monitor plant height throughout production and identify when plants are too tall or too short.

  • Trending: PGR sprenches

    Published on April 17, 2015
    A sprench of a plant growth regulator (PGR) is a hybrid of a spray and a drench application, and is increasingly being used in the production of greenhouse ornamentals.

  • The ABCs of PGRs

    Published on November 18, 2008
    There are now a large number of plant growth regulators registered for use on ornamental plants. This article discusses the various active ingredients and the product names for each.
