  • Improving perennial flower (Vernalization part 5)

    Published on June 29, 2006
    In part 5 of a 5-part series of articles on vernalization of herbaceous perennials, this article discusses plants in which a cold treatment accelerates or improves flowering, but is not necessarily required for flowering.

  • 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.

  • New, high-resolution, interactive DLI maps

    Published on October 10, 2018
    New maps of the photosynthetic daily light integral (DLI) in the United States have been developed and are now available online.

  • Controlling flowering of Echinacea

    Published on February 8, 2013

  • 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.

  • 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?

  • Energy-efficient annuals 10: Vinca & wax begonia

    Published on December 22, 2009
    Researchers from Michigan State University present research-based information for scheduling vinca and wax begonia in an energy-efficient and predictive manner. Part 10 of a 12-part series.

  • Evaluating different colors of LEDs to control flowering

    Published on December 10, 2014
    Researchers at Michigan State University tested the effectiveness of various LED colors. Read to learn how they affected flowering.

  • Quick-cropping perennials

    Published on September 29, 2004
    Research-based information is provided to commercially produce a variety of herbaceous perennials in flower, in a relatively short period of time.

  • Replacing incandescent lamps

    Published on August 23, 2012
    Incandescent lamps can at least partly be replaced by compact fluorescent bulbs and/or LEDs without losing the ability to control flowering of ornamentals grown in greenhouses.

  • Environmental & genetic approaches to lower greenhouse heating costs

    Published on March 22, 2012
    To lower energy costs for greenhouse heating, we have taken two approaches: to optimize greenhouse temperature on a species- and seasonal-basis, and to develop genetic resources to help facilitate the breeding of crops that flower earlier.

  • Answering key questions about indoor crops

    Published on November 9, 2022
    In part three of a four-part series, we discuss crops suitable for indoor farming, planting densities, harvest times, and other commonly asked questions about growing crops indoors.

  • Consumer perceptions of sustainably produced poinsettias.

    Published on August 9, 2009
    Are consumers interested in locally, organically or sustainably produced poinsettias? The authors conducted research to find out.

  • 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.

  • Crops suitable for vertical farming

    Published on April 10, 2019
    The costs to build and operate an indoor (vertical) farm are high, so only certain types of crops are potentially profitable. This articles discusses some some of the crop characteristics that lend themselves to indoor production.

  • Growing ornamental seedlings under different wavelengths of red light from LEDs

    Published on August 23, 2014
    Plants grew similarly under different colors of red light, so the choice of red LEDs to be used for horticultural applications could depend on factors such as LED longevity, efficacy, and cost.

  • Improving crop quality

    Published on June 6, 2012
    improving crop quality

  • Keeping [geranium cuttings] green

    Published on December 19, 2013
    How to reduce lower-leaf yellowing of geranium cuttings in propagation.

  • A closer look at far-red radiation

    Published on May 7, 2016
    Far-red light can be defined as photons with wavelengths from 700 to 800 nanometers. It can promote extension growth and flowering, and at least indirectly increase growth.
