Organic Practices

The shift to sustainable landscape practices began in 1979 with the implementation of an Integrated Pest Management (IPM) program. Our IPM program differs from many others in that chemical pesticide applications are not considered a viable last option. Only OMRI rated products are used on the campus grounds. We use a combination of methods that focus on total plant health, particularly at the soil level, to mantain our grounds. Some of the components of our program include:

  • Weed suppression, not eradication
  • Compost top-dressing
  • SU compost and wood chip mulching
  • Centralized control of irrigation and monitored water use
  • Responsible Plant Selection 
  • Beneficial Insect Release 
  • Nutrient cycling 
  • Compost Tea application 
  • Encouraging Beneficial Insect and Bird Populations

In 2009, SU Grounds worked with O'Brein and Co. to create a landscape managenment plan that outlines and defines all of our practices. Landscape Management Plan
