Organics and the New American Lawn Plan

In Jonathan Green’s New American Lawn Plan, both organic and synthetic fertilizers are used to encourage lawn grass growth. This balanced approach produces great results! Synthetic fertilizer works more quickly in cold, spring soil. Later in the year, after the soil has warmed to approximately 57 degrees Fahrenheit, organic fertilizers work very well.

Great New American Lawns result when genetically superior turf-grass varieties, like those in our Black Beauty Grass Seed Mixtures, are grown in healthy biologically active soil.

When To Feed Your Lawn

Lawn Care Calendars for the New American Lawn
Applying The New American Lawn is so easy with our feeding calendars! Just choose one of the three Program Application Wheels below that best suits your needs, and follow the lawn and soil food schedules.

STANDARD APPLICATION SCHEDULE | WHEEL 1: If you are NOT seeding this spring, then use our Standard Program wheel. It is the most popular NAL fertilizer program.


If you ARE seeding this spring, then use our Seeding Program wheel.


If you want to apply ONLY organic products to your lawn, then use our Organic Program. Eventually, we’d like all customers to graduate to the Organic Program. However, if users have had many weed problems on their lawn in the past, then we recommend using one of our other programs for a few years, and once the weeds are under control switching to the Organic Program.
