Organic Land Care: lawns, gardens and landscapes
First, Do No Harm
Every land use decision we make will have a positive or negative effect on the land in our care. Strive to understand and preserve existing elements that benefit the whole ecosystem––indigenous plants and soils, wildlife corridors and habitat, riparian buffers and watershed drainage, mature trees and shrubs. Minimize use of inputs that impact existing local ecosystems, such as fertilizer and water, and avoid adding any toxic materials to the land in your care.
- Keep pesticides off your lawn and gardens
- Using only non-toxic materials on your property reduces the health risk to yourself, your family, your neighbors and your local environment. See Why Organic?
- Use non-synthetic fertilizers from natural sources
- Synthetic fertilizers are made in a chemical process that uses fossil fuel and contributes to global warming. Use of synthetic nitrogen fertilizer greatly increase the amount of nitrogen entering the global nitrogen cycle which has a serious negative impact on the organization and functioning of the world's ecosystems, including accelerating the loss of biological diversity and decline of coastal marine ecosystems and fisheries. Visit www.epa.gov/watertrain/nitrogen.html for more information. The use of synthetic phosphorus fertilizers has its own set of problems, in particular its contribution to the eutrophication of fresh water lakes and ponds, and the limited global supply of phosphate rock.

- Reduce water use
- In many cities in the Northeast, 50% of the drinking water goes to lawns and landscapes. Over 75% of our rivers are flow stressed because of water withdrawals for these residential uses. Read more in our article "Lawns: Good Watering Practices"
- Remove invasive plants
- Invasive plants grow quickly and spread easily and often reduce the biodiversity of whole ecosystems. Learn about invasive plants, how to avoid spreading them, and how to remove them from your own property. In the U.S., a good place to start is at the National Invasive Species Information Center, www.invasivespeciesinfo.gov
- Home gardening with native plants
- Native plants are site adapted and usually require little to no watering, fertilizing or pesticides. Stunning gardens can be made from entirely native plants. See our bookstore for ideas. Since native plants are, well, native, it's best to find a local conservation group who works with natives. If you live in the Northeast U.S., a good place to start is the New England Wildflower Society, www.newfs.org/learn. They have a listing of Native Plant Societies in the US and Canada, http://www.newfs.org/publications-and-media/resources/nps.html
- Make and use compost
- Compost has many advantages as a soil amendment and it is less likely to cause pollution of the local and regional environment than fertilizers, even organic ones. Incorporating compost improves turf, shrub and shade tree performance in marginal or poor soils. Good quality compost improves soil structure, reduces runoff and compaction, enhances biodiversity, increases water and nutrient retention, increases microbial activity, supplies nutrients, helps suppress and prevent plant diseases, detoxifies certain pesticides, and inactivates and kills potential human pathogens. The benefits to the plants are: improved establishment of turf, ornamentals and shade trees; improved color; increased root growth; and reduced need for fertilizer, pesticides, and irrigation. To learn more about compost, you can start at EPA's site: http://www.epa.gov/osw/conserve/rrr/composting/
- Test your soil
- If you want your property to look its best, to save money, and to protect the environment even more, do an easy soil test before you apply anything at all. A soil testing lab will be help you figure out how much of which fertilizers and nutrients to apply for optimum results.
- Increase biodiversity
- Biodiversity is the key to a healthy ecosystem on any scale, from backyard to global. Biodiversity increases the stability of ecosystems, reduces the need for intervention, and makes them, from an aesthetic viewpoint, much more interesting. The earth is currently losing species at a rate that rivals mass extinctions in our geologic record. You can use the American Museum of Natural History's site as a starting point to read about why biodiversity is important, http://cbc.amnh.org/. You can look at the National Wildlife Federation site to learn how to increase biodiversity in your own back yard.
- If you have a lawn...
- Mow high, 3"-4"; leave grass clippings on lawn; water infrequently, if at all; encourage a bit of white clover; and fertilize with compost and overseed bares spots in fall and early spring. See more at Lawn and Turf below.

Lawn and Turf Course
We offer a one-day intensive Organic Lawn and Turf Course. This course targets specifically the needs of professionals managing lawns and athletic turf in residential, commercial, or public settings such as schools and parks. We offer this course annually in a New England state and have trained over 500 students in organic turf management.
The NOFA Organic Lawn and Turf Handbook, 2007
This 104-page, comprehensive and practical handbook details methods for
growing and managing beautiful, healthy, organic turfgrass. Written and
edited by scientists and NOFA accredited organic landscapers as a natural
companion to NOFA’s professional organic lawn and turf courses, it also
stands alone as a unique and valuable resource for all landscapers.
This book is aimed at professionals but will be a useful resource for anyone
interested in creating beautiful organic lawns, parks or athletic fields in the
Northeast. You can purchase this and other books from our books store.
Basic Principles of Organic Land Care
- Steward the combined health of soil, plant, animal, human, and planet.
- Emulate living ecological systems and cycles and help sustain them.
- Build equity, respect, justice, and stewardship of the shared world.
- Act in a precautionary and responsible manner.

"I just loved the course – I started learning in the first five minutes. With a soup-to-nuts syllabus that covers all the issues imaginable taught by a gathering of the region’s most esteemed scientists, this is value-added education at its best." -Tovah Martin, 2010
The cornerstone of our educational program is our 5-day Accreditation Course, a 30-hour, comprehensive course based on our written standards. It is also the gateway to becoming an Accredited Organic Land Care Professional. This course covers all aspects of organic land care from soil health, site analysis and planting/plant care to composting, lawn alternatives and running a business. It offers 20 speakers over five days, interactive case studies, and a client relations panel featuring professionals working in the field. The accreditation exam is given on the last day of the course. Those who pass are eligible to become Accredited Organic Land Care Professionals (AOLCPs) and pledge to practice according to the NOFA Standards for Organic Land Care for those clients who ask for organic landscaping. This course is now offered in CT, MA, and RI and has trained over 1000 professionals since its inception in 2002.
