Weeds compete with your lawn for sunlight, water, and nutrients, quickly taking over if left untreated. At Green Island Tree & Lawn Care, we prevent weeds before they sprout with pre-emergent treatments and eliminate existing ones with targeted applications. Our seasonal approach, tailored to Long Island’s conditions, ensures effective, long-lasting results—you’ll notice a difference after just one visit.

  • Eliminates weeds before they spread
  • Prevents weeds from stealing water and nutrients
  • Enhances lawn health and curb appeal

Client Reviews

"Have been using Green Island for well over 5 years, and our yard is Never buggy, as we get sprayed every month. We go to other friends yards and get bitten all the time, and when they come here they always comment on our yard."
