Fight Climate Change with ORI’s Clean Water and Green Lawn Movement

-Say no to quick-release nitrogen fertilizers

-Only apply fertilizer once a year (in spring or fall)

-Apply no more than ½ pound per 1000 feet of slow-release fertilizer

-Refuse the use of RoundUp


Ten ways you should modify your lawn care to help the environment


1. Before you spread pounds of quick-release fertilizer, consider letting your lawn combat climate change by switching from quick-release to slow-release nitrogen fertilizer.

2. Stop spreading fertilizer so frequently; with

slow-release nitrogen fertilizer, you may only need to apply 1/2 pound in the spring or fall, or none at all. 

3. Let your grass grow a bit taller. At a recommended 3 inches, lawns grow deeper roots and are able to form stronger underground systems for water and carbon uptake.

4. Don’t trash grass, spread your grass clippings on your lawn for a free and effective fertilizer boost (about 1 lb fertilizer per 1,000 ft sq of lawn)

5. Fertilize only in the spring or fall, not in the summer when there is higher rates of runoff or the winter when your grass is dead anyway!

6. Always opt for grass or gardens over impervious surfaces for maximum carbon capture.

7. Replace your patio with a lawn to sponge up excess storm water when extreme weather hits.

8.  Allow green lawns to coexist with clean waters by only using fertilizer when you absolutely need to.

9. Think about where most of your fertilizer is going, especially if you live near wetlands. Being conscious of your lawn runoff could prevent harmful algal blooms.

10. Remember this: it’s not lawns that pollute, it’s quick-release fertilizer that is weakening your lawn and causing pollution. Work smarter, not harder by replacing quick-release with 100% slow-release for a green lawn and for clean water – no harmful algal blooms.

Fight climate change, pledge here to change your lawn care to stop nitrogen pollution and increase carbon capture; tell what works best for you.
