Feed your lawn safely and effectively. We design custom fertilization programs utilizing organic-based, slow-release nutrients tailored to Vineyard soil profiles.
Lawn fertilization on Martha's Vineyard uses organic-based, slow-release nutrients matched to the property's soil test. Infinity Landscaping designs 4 to 6 application programs across the season, complies with local fertilizer regulations (including phosphorus restrictions), and times applications to soil temperature and rainfall. Products are safe for children and pets once dry - typically 1 to 2 hours after application.
Lawn Care
What this page covers
Custom soil testing
Every property has different soil conditions. We collect core soil samples across your lawn to analyze key nutrient levels, organic matter percentages, and pH levels, allowing us to build a precise, science-backed fertilization plan.
Organic-based nutrients
To protect the Island's sensitive groundwater and coastal ponds, we prioritize organic-based, slow-release fertilizers. These products feed the soil biology and release nutrients steadily, promoting strong roots and color without leaching.
Lime & pH correction
Vineyard soils are naturally acidic, which prevents grass roots from absorbing nutrients effectively. We apply pelletized limestone treatments to balance soil pH, improving fertilizer efficiency and lawn health.
Micro-nutrient treatments
Grass needs more than just nitrogen. We apply essential trace minerals-including iron, magnesium, and calcium-to improve disease resistance, root cell structure, and the deep green color of your turf.
Lawn Care
Fertilizing for sandy Island soils
Because Martha's Vineyard soils are highly sandy, they have a low Cation Exchange Capacity (CEC)-meaning they cannot hold onto nutrients easily. Standard, quick-release synthetic fertilizers applied to sandy lawns simply wash through the root zone during rain or irrigation, polluting the groundwater and nearby marine bays.
Our fertilization strategy focuses on building the soil's organic structure. By applying organic-based fertilizers, natural compost inputs, and humic acids, we increase the soil's ability to hold water and retain nutrients. This method feeds the beneficial soil microbes, creating a self-sustaining ecosystem that supports deep grass root growth and natural drought resistance.
Process
Our annual fertilization steps
01
Soil Analysis
We collect soil plugs in early spring to test pH and nutrient baselines.
02
Spring Feed
Apply slow-release organic fertilizer to kickstart root development and color.
03
Summer Support
Apply low-nitrogen organic nutrients and iron to sustain color without pushing excessive top growth during hot weeks.
04
Early Fall Feed
Apply nitrogen-rich organic blends to help the lawn recover from summer stress and support root density.
05
Late Fall Winterizer
Apply late-season nutrients to store carbohydrate reserves in roots for early spring green-up.

Frequently asked questions
Yes. Our organic-based and natural fertilizers are safe for family and pets. We recommend keeping children and pets off the lawn during application and until any liquid treatments have dried, or granular products have been watered in, typically 24 hours.
Lawn grasses prefer a slightly acidic to neutral soil pH (6.2 to 6.8). If your soil is too acidic (common on the Island, where pH often drops below 5.5), grass roots cannot absorb nutrients, even if fertilizer is applied. Regular lime applications help raise pH to the ideal range.
Yes. Martha's Vineyard has specific regulations governing fertilizer application to protect water quality. We strictly adhere to these rules-including bans on winter applications, limits on total nitrogen per application, and restrictions on phosphorus unless a soil test proves a deficiency.
Because slow-release and organic fertilizers depend on soil microbes to break down nutrients, you will see a gradual improvement in lawn color and density over two to three weeks, rather than an instant, chemically forced surge. This steady growth builds a healthier, more resilient lawn.
