  • 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.

  • What's All the Hype on Poinsettia Micro-Drenches?

    Published on August 21, 2021
    How do PGR micro-drenches compare to one heavy PGR drench on two red poinsettia cultivars?

  • 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.

  • 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.

  • Improving branching and postharvest quality

    Published on August 18, 2008
    When used properly, benzyladenine (BA) sprays have commercial potential, and can increase the number of tertiary shoots in poinsettia and delay lower-leaf yellowing (chlorosis).

  • Height control for vegetable transplants

    Published on February 18, 2010
    A supplemental labeling of Sumagic for use on vegetable transplants in the U.S. has made height control less complicated. There are a few other methods that may be helpful, too.

  • How to avoid GA carryover

    Published on August 18, 2010
    Gibberellins (GA) can bind to plastic and concrete, and potentially cause excessive growth, especially in sensitive crops.

  • PGR dilution guide

    Published on April 18, 2013
    A critical factor for effective use of plant growth regulators (PGRs) is that the solution is mixed in the appropriate concentration.

  • Height control of perennials: What works and what doesn’t

    Published on August 17, 2020
    This article discusses height control techniques that generally do or don’t work for herbaceous perennials forced into flower.

  • Going beyond the surface

    Published on September 18, 2009
    In some cases, adding a surfactant to a plant growth regulator solution can improve the product’s efficacy and increase uptake. How can you know when to use these products?

  • Ethylene in floriculture

    Published on January 7, 2019
    Ethylene can be a harmful contaminant in greenhouses and during shipping, but there are also situations when ethylene can elicit desirable responses in greenhouse crop production.
