Lawn, Field, and Tree Care

Wesleyan has significantly cut back on chemical weed control on all campus grounds and now use both organic and synthetic weed treatments for crabgrass, invasive plants, and grub control. Wesleyan's integrated pest management (IPM) program was developed by Dave Hall in coordination with New England Turf Management and Stonehedge Landscaping.  In an effort to continue to minimize pesticide use, the campus is divided into 3 separate categories.  These areas include; 100% Organic Treatment, 60% Organic Treatment, and the Athletic Field areas.  The first two areas are maintained by New England Turf, and the athletic fields are maintained by Stonehedge Landscaping.

100% Organic Treatment Areas

Foss Hill, Butterfields, West Side of Mt. Vernon Avenue, High Rise dorm, Neighborhood Preschools on High St. and Lawn Ave.

  • No pre or post-emergent pesticides for crabgrass or other weeds
  • No treatment for grub control

60% Organic Treatment Areas 

Remainder of campus excluding the athletic fields, including the Rugby Field

  • 4 of 6 yearly applications use 100% organic fertilizer; the remaining 2 applications are 50% organic
  • Dimension is applied in granular form in the spring as a crabgrass preventative; applied only on an as-needed basis during the rest of the year
  • Triplet Low Odor is applied in liquid form and used as a selective herbicide for broadleaf weeds
  • Acelepryn is applied in granular form in early summer to treat grubs (Merit had been used in the past but was discontinued because of safety concerns)

Athletic Field Areas

All athletic fields, excluding the Rugby field

  • The IPM program for athletic fields is continually changing based on environmental pressures
  • Wesleyan maintains fields most strictly for player safety and field playability, with a high priority placed on field appearance
  • Dimension is applied in granular form in the early spring as a crabgrass preventative
  • Other fungicides, herbicides and grub control are used on an as needed basis (may be granular or liquid)
  • Stonehedge has experimented with a 100% organic fertilizer on Jackson Field that worked well but is currently too expensive for regular use
