Types Of Landscape Materials We Carry

We carry a wide range of landscape materials for both large commercial work and residential projects. Our selection includes:

Bulk Mulch
Bulk Topsoil
Compost
Lawn Care Products
Specialty Mixes

These materials are used for everything from final finish grading and seeding to bed preparation, tree and shrub installation, and seasonal property cleanup. Contractors come to us when they need dependable supply and efficient loading. Homeowners usually need the same materials, just in smaller quantities and with a little guidance on what works best for the project.

Brand Options

We stock trusted brands that our customers ask for when performance matters and the material needs to match the job.

Alliance products are a strong fit when you are working around paver and hardscape areas and want supporting materials that help complete the install properly.

Espoma is a go-to for planting, soil improvement, and lawn and garden care. It is a solid choice for homeowners and contractors looking to improve growing conditions and support healthy root development.

Jonathan Green is well known for lawn care products, especially when appearance, coverage, and seasonal lawn maintenance are part of the job.

Reed & Perrine is a familiar name for dependable lawn, garden, and landscape support products that help with routine maintenance and property improvement.

Where Landscape Materials Get Used

Landscape materials get used in nearly every outdoor project. Contractors use bulk topsoil and mixes for grading, lawn prep, and backfilling around planting areas. Compost helps improve poor soil and is often worked into garden beds before planting. Bulk mulch is one of the most common finish materials for clean-looking beds, moisture retention, and weed suppression. Lawn care products help keep finished jobs looking sharp after installation.

We see this a lot, a project looks simple until the wrong material shows up for the finish layer. A real tip we give at the counter is to plan your depths before ordering. Mulch, topsoil, and compost all spread differently depending on the area, so knowing your square footage and target depth saves time, waste, and extra trips.
