Webinar on PGR tips for Michigan greenhouse growers

Tune in March 16 for a free webinar on plant growth regulator (PGR) tips for Michigan greenhouse growers.

March 7, 2018 - Author: W. Garrett Owen, Michigan State University Extension

March: It’s not just a month on the calendar, but five intense weeks where greenhouse growers are filling every square foot of greenhouse space with Michigan-grown ornamental bedding plants. During this time, growers are focused on producing the highest-quality plants by monitoring plant nutrition, maintaining the greenhouse environment and managing cultural practices. One cultural practice that assists growers in producing high-quality bedding plants is applying plant growth regulators (PGRs).

Plant growth regulators are an integral tool used in floriculture production. Optimal rates help manage plant growth for well-branched, compact plants (Photo 1). However, when rates are excessive, plant growth can be stunted (Photo 2). A free webinar from 12-1 p.m. on March 16, 2018, will focus on PGR tips and rates that are specifically tailored to growers in the northern U.S.

  • Low- or late-season drenches for growth control
  • Balancing phosphorus and PGR applications
