Organic Lawn Care
The safest way to a beautiful lawn is to work with nature, not against it.
"Organic Lawn Care" focuses on the soil to build a beautiful, deep-rooted, dense
lawn. Costs and maintenance requirements are lower vs. synthetic pesticide lawn
care programs after the first one to two years. Comparative cost analysis study.
Synthetic pesticides (e.g., herbicides, insecticides, fungicides, etc.) and
synthetic fertilizers used in traditional lawn care programs are associated with
risks which are especially consequential for
pets (fact sheets provided by BeyondPesticides.org). Synthetic pesticides and synthetic
fertilizers trap lawns into an unhealthy and expensive cycle of chemical
dependency. For a discussion of the benefits of organic fertilizer over synthetic fertilizer,
Organic lawn care can be done on a do-it-yourself basis (Brochure,
Videos) or by a lawn care professional specializing in the process.
NOFA (The Northeast Organic Farming Association) offers
the an organic lawn care accreditation program for professionals. NOFA-NJ offers a list of
accredited and unaccredited NJ organic lawn care professionals,
while NOFA offers a list of accredited organic lawn care professionals in the eastern U.S.
NOFA-NJ offers courses on organic lawn care for homeowners and professionals.
If you live in a condominium or rental community, discuss hiring an organic lawn care
professional with your board or property manager. Until this occurs, be aware that per the
NJDEP Pesticide Control Program (Subchapter 9 - Pesticide Exposure Management, 7:30-9:13 -
Notification: Turf or Ornamental Applications) you have the right to receive - upon request
- advance notification of any pesticide applications as well as the pesticide labels.
In 2008 Bernards Township, NJ adopted an
Integrated Pest Management Resolution covering all township owned property. The policy utilizes
organic lawn care practices allowing for the elimination of synthetic pesticides and synthetic fertilizer on all sports fields and key
lawn areas, and it designates all parks as Pesticide Free Zones. The Board of Health supported the policy by passing
Resulotion BH 10:09, and
the Board of Education followed with their own policy declaring that school lawns and sports fields
shall be managed without lawn care pesticides. The Mayor, the Township Committee, the Board of Health, the Green Team, the Board
of Education, and the Environmental Commission encourage all citizens to participate in this endeavor on their own property.

Organic Lawn Care Basics
This is a short summary of what you will find in the brochure and video links above as well as in the materials below:
- Feed the Soil - Add compost and liquid "compost tea" to the lawn.
- Feed the Turf - Leave grass clippings (mulched, ideally) in the lawn to recycle nutrients and add organic matter.
Fertilizer needs will be reduced by at least 25%. Replace synthetic fertilizer with organic fertilizer
(look for organic fertilizers which say they are "OMRI Listed" on their packaging) to build the soil, feed the turf,
and reduce watering needs by 30% according to Harvard's findings.
- Overseed - Thick turf out-competes weeds. Apply seed over the existing lawn in early fall, and aerate the soil. Consider using a diversity of seed types to strengthen the turf's resistance to disease impacting a single type of turf. Note that tall fescue, fine-leaf fescue, and perennial ryegrass turf grass types are advantageous as they contain fungi which in turn create compounds which are toxic to certain grubs.
- Test the Soil - Soil tests identify the need for amendments (typically lime (calcium) to raise the pH) and fertilizer nutrients. A soil pH between 6 and 7 is required for weed prevention. See the fertilizer link above for a link to the local soil test lab.
- Mow High - Cutting the grass height at 3-4 inches helps reduce watering needs by allowing the soil to retain more moisture, and it also prevents weeds. Keep mower blades sharp to limit disease.
- Water Only As Needed - Too much water makes lawns vulnerable to disease and encourages shallow turf roots which is detrimental the turf's self-sufficiency. 1" of water per week, delivered in a short interval, is optimal to foster a strong deep-rooted turf.
- Weed Control - Corn gluten, applied during spring when the Forsythia bloom, prevents weeds from germinating. For spot weed control on sidewalks and driveways, use a lemon juice & vinegar mixture.
- Pest Control - Common lawn insects can be controlled in the current season with beneficial nematodes. Longer term, Milky Spore Powder controls for Japanese beetle grubs. Organisms in compost and liquid "compost tea" helps keep lawns healthy and pest-free.

Movies and Videos
The DVD movie A Chemical Reaction chronicles the origin of the organic lawn care movement in Canada and the U.S.,
and it also serves as an educational vehicle for individuals and organizations interested in reducing or eliminating
lawn care pesticides.
The How to Make the Organic Lawn
Care Transition DVD won a major award from the Garden Writers Association of America, and is
available from SafeLawns.org. The DVD includes 16 how-to segments that cover an entire season of lawn care from spring through fall.
