  • 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.


  • Managing crop height

    Published on February 3, 2021

    Professor Emeritus Royal Heins discusses the history of DIF, which is the temperature difference between the day and night, and how it can be used to manage plant height of floriculture crops produced in greenhouses. He also discusses graphical tracking of the height of potted flowering plants to help growers achieve their desired height targets.

  • Control stem length with liner dips

    Published on November 18, 2011
    Dipping trays of rooted liners and plugs into a PGR solution, or liner dip, is a newer method of efficiently applying root-absorbed PGRs that controls stem elongation after transplanting.

  • Success with PGRs

    Published on March 18, 2019
    Regardless of the desired outcome, successful use of a plant growth regulator (PGR) requires multiple considerations and attention to detail. This article summarizes practices to obtain the best results from your PGR applications.

  • Sumagic on vegetable transplants

    Published on November 18, 2012
    Sumagic is the only plant growth retardant registered for use as a foliar spray on young tomato, pepper, eggplant, groundcherry, pepino and tomatillo plants.

  • Understanding how PGRs work

    Published on May 17, 2017
    Plant growth regulators are chemical compounds that regulate various growth and developmental processes in plants, such as seed germination, rooting, branching, flowering, fruit development, dormancy and plant growth habit.

  • Increasing height of chrysanthemum with PGR drenches

    Published on July 10, 2017
    Results are presented for an experiment in which we compared the efficacy of spray versus drench applications of a plant growth regulator (PGR) at increasing plant height of potted chrysanthemum plants.

  • Effective use of PGRs

    Published on July 18, 2014
    Plant growth regulators (PGRs) are sometimes not used to their potential; they are sometimes applied too late or at an inappropriate rate. Here are some important considerations for getting the most out of your PGRs.

  • Increasing poinsettia size

    Published on October 18, 2007
    Are your potted poinsettias vertically challenged? When applied on young stems before the first hint of color, chemicals can help promote stem extension and take your plants to new heights.

  • Successful use of paclobutrazol

    Published on April 18, 2012
    Paclobutrazol is probably the most widely used plant growth retardant in the production of floriculture crops because of its wide range of efficacy and moderate- to long-lasting response.

  • PGR drench guidelines

    Published on April 18, 2007
    A drench of a plant growth regulator (PGR) is an application of a relatively large volume of solution at a low concentration to the growing media. Learn more about which chemicals are appropriate for drenches, as well as suggested volumes and rates.

  • Maximizing PGR spray applications

    Published on April 18, 2010
    Despite the availability of many different plant growth regulators, their spraying methods are generally similar. How can you get the most out of each application?

  • Know your application techniques

    Published on August 18, 2006
    Be sure to select the proper plant growth regulator application technique to achieve your desired crop size.

  • Sumagic on bedding plants

    Published on April 18, 2005
    Usage of this highly active plant growth regulator (active ingredient: uniconazole) on bedding plants is for the experienced commercial grower. Read how to use it, when it’s best used, and how much is recommended based on this MSU research.

  • Using the PGRs Collate and Florel

    Published on June 18, 2013
    Achieving consistent results with the plant growth regulators (PGRs) Collate or Florel can be trickier than with other PGRs simply because the active ingredient, ethylene, is a gas.

  • Managing perennial stock plants with Florel

    Published on August 18, 2004
    Michigan State research determines whether Florel (active ingredient: ethephon) can be used as a tool to keep perennial stock plants vegetative and increase the number of cuttings harvested for six species of herbaceous perennials.

  • Controlling height with temperature drops

    Published on April 17, 2009
    Temperature drop is the practice of lowering the temperature, typically by 5-15 degrees F, before sunrise. Generally, the greater the magnitude of the temperature drop, the stronger it suppresses plant height.
