Fertilizers
When you need fertilizers for jobs across Long Island and NYC, it helps to work with a yard that understands how contractors buy and how homeowners plan. At 9 Brothers Building Supply, we stock fertilizer options for lawn care, landscape work, and seasonal property maintenance, and we help customers choose the right blend for the conditions on site. We serve contractors first, but we also work with homeowners who want solid products and straightforward advice. With yard locations in Brentwood, East Setauket, and Riverhead, our team can help you pick up fast or schedule delivery where it makes sense.
Types Of Fertilizers We Carry
We carry fertilizer blends for different stages of turf and landscape care, including:
- 16-0-2
- 20-0-5
- 32-0-4
- 5-0-3
- 8-18-12
Each formula serves a different purpose. Some are better suited for promoting green-up and steady turf growth, while others are more useful when phosphorus and potassium matter for rooting and establishment. Our customers ask about timing all the time, and that is usually the first place to start. A spring feeding plan is not the same as what you want for fall recovery or new seeding work.
Brand Options
Reed & Perrine is a trusted name for fertilizer programs used by landscape professionals and property maintenance crews. Contractors like the consistency, and homeowners appreciate having dependable options without overcomplicating the job. When you are maintaining lawns, improving appearance, or supporting new growth after installation, this is the kind of brand people come in asking for by name.
Where Fertilizers Get Used
Fertilizers get used across a wide range of residential and commercial projects. Contractors use them for lawn installations, seasonal maintenance, sports fields, commercial grounds, and property upgrades where curb appeal matters. Homeowners usually come in looking to improve patchy turf, support new seed, or keep established lawns healthier through the season.
Here’s a real tip we give at the counter, match the fertilizer to the job stage, not just the color you want to see next week. For example, a property with fresh seed or a new lawn install may need a different approach than an established lawn that just needs feeding. We see this a lot, people rush the application or put product down before checking weather and watering plans. It is always smarter to plan around rainfall, irrigation access, and mowing schedule so the fertilizer has a better chance to do its job.
