NOFA-ACCREDITED ORGANIC LAND CARE SPECIALISTS
Organic Lawn Care on Long Island, NY
From an organic approach to complete organic programs.
At Emerald Magic, we are NOFA-accredited organic land care specialists. That means you are not stuck with one way of doing things: we offer a range of options and levels of service, from an organic approach to complete organic programs. It is part of a bigger belief that runs through our whole company: making the world a greener place while educating our clients and neighbors about beneficial environmental practices.

Why Organic Care Resonates on Long Island
Long Island is an island in more ways than one. Our drinking water comes from the aquifers beneath our own neighborhoods, and the bays, harbors and creeks that make this place special sit just downhill from our yards. Many homeowners want a beautiful lawn that also respects the water, the wildlife and the places their children and pets play.
Sandy glacial soil adds another wrinkle. Lean, fast-draining ground holds little organic matter on its own, so building soil health is a natural focus for any lawn here, organic or not.
Organic land care puts the soil first. It treats the lawn as a living system, and it asks a little patience in return. For many families, that trade feels just right.
Choose Your Level of Organic Care
An organic approach: for homeowners who want to lean organic within a flexible program.
Complete organic programs: for homeowners who want their lawn care to be fully organic.
Guidance from NOFA-accredited specialists: we explain each option so you can choose with confidence.
Seeding that fits: from minor repairs to total lawn renovations, to thicken turf and leave less room for weeds. See aeration and overseeding.
Eco-friendly pest options: our pest control uses eco-friendly and sustainable methods where they fit. See tick and mosquito control.

How We Help You Go Organic
01
Look closely
Like every Emerald Magic program, organic care starts with an inspection of your lawn, so recommendations fit your soil and your goals.
02
Talk it through
We walk you through the options, from an organic approach to a complete organic program, and answer your questions honestly.
03
Care for the lawn
Our team applies your program and monitors your lawn and landscape for developing horticultural issues.
04
Keep learning together
We advise you periodically on watering and mowing best practices, because good habits at home are a big part of any organic lawn.
Organic Thinking in a Coastal County
Suffolk County stretches from the bluffs of the North Shore to the barrier beaches of the South Shore, with the Pine Barrens in between. The Pine Barrens protect some of the purest groundwater on Long Island, and the Great South Bay, Moriches Bay, Long Island Sound and the Peconic estuary are all close to home for most of us. Caring for the land with that water in mind is simply part of living here.
Organic land care fits those values. It emphasizes soil life, healthy grass and thoughtful choices, and it lines up with our own promise to minimize the environmental effects of applications by monitoring and applying as needed to achieve great results.
It also fits the wider community work we love. Owner Craig den Hartog’s passion project, Old Town Blooms, has brought neighbors together to plant over 50,000 daffodils along Old Town Road and surrounding areas. Greener neighborhoods start one yard at a time.
Seasons of an Organic Lawn
Organic care is a long game. Patience and good habits at home help it pay off season after season.
Spring
Grass wakes up and the soil starts to come alive. It is a good time to review your goals and settle on the level of organic care you want.
Summer
Heat and dry spells test every lawn. Deep, early-morning watering and the right mowing height help organic lawns ride out stress.
Late summer and early fall
The best time to seed on Long Island. Thickening the turf is one of the most natural ways to crowd out weeds.
Late fall and winter
The lawn rests and roots store energy. It is a good time to plan the next season with your specialist.
Why Choose Emerald Magic for Organic Care
Organic land care is a specialty, and our NOFA accreditation reflects that. Owner Craig den Hartog, a horticultural consultant and environmental enthusiast, strives to educate both employees and clients about beneficial and healthy lawn and landscape practices on Long Island, and he regularly attends seminars on leading green industry practices.

Organic-Friendly Habits at Home
Mow high and often so the grass shades out weed seeds.
Water deeply, less often, and early in the day, to encourage deeper roots.
Return clippings to the lawn instead of bagging them.
Overseed thin areas in late summer or early fall, the best seeding window on Long Island.
