Services
Lawn Fertilization
Our 5x yearly fertilization program uses granular slow-release formulas to nourish lawns throughout the growing season. Tailored applications ensure optimal growth, color, and resilience against environmental stressors while maintaining eco-friendly practices.
Weed Control
Targeted broadleaf weed controls and pre-emergent crabgrass treatments eliminate invasive species without harming turf health. Precisely timed applications prevent regrowth and maintain a uniform, attractive lawn appearance year-round.
Disease Treatment
Expert diagnosis and treatment of fungal infections like Red Thread, Dollar Spot, and Brown Patch using advanced products. Customized solutions restore lawn health and prevent future outbreaks through proactive monitoring and care.
Turf Restoration
Comprehensive aeration, seeding, and soil cultivation techniques revive severely damaged lawns. Our Long Island-specific seed mixtures and deep-root aeration promote dense growth without costly sod replacement.
Insect Control
Effective eradication of grubs, sod webworms, and chinch bugs using targeted treatments. Our integrated pest management approach protects turf integrity while minimizing environmental impact through responsible application methods.

Report
I started using them 2 years ago. What a dramatic difference in my lawn over that span, I regret not having switched to them years ago. My lawn is weedless, full and green. They are extremely responsive as well. I could not be happier with my lawn and their service. Rarely does switching companies work out so well. Great service all around.

Report
I was previously using a company for my lawn chemical needs (for years) and thought it may be time for a change. I'm not big on change but it was the best move I've made in a long time. In 2 years (just completed my second season) my lawn went from zero to hero. They are very professional, punctual, and have made separate visits upon request to address an immediate need. My lawn is green and full (The aeration is a night and day comparison to my old company). I can't be happier. I don't write many reviews but these guys deserve one. Use them.
