What Mark Coulbourne Inc. supplies

Full-line landscape supply yards stock soil, mulch, decorative stone, boulders, pavers, edging and often sod under one roof. That matters when a project needs several materials, because combining them into a single delivery avoids paying separate trip charges to multiple suppliers.

Loose material is normally priced by the cubic yard while stone is priced by the ton, so compare quotes carefully — the two units are not interchangeable and a cheap-sounding per-ton price can work out dearer.

Garden centers carry bagged soil, compost and mulch alongside plants and often sell bulk material from a yard out back. That combination is convenient when a planting project needs both the medium and the stock in one trip.

How much material you need

Landscape materials is sold by the cubic yard. Delivery vehicles vary; a tandem dump truck carries roughly 10–12 yards, while smaller trucks top out near 5.

As a rough guide: 1 yard covers about 100 sq ft at 3 in; 5 yards covers about 540 sq ft at 3 in; 15 yards covers about 1,620 sq ft at 3 in.

Measure your area and decide on depth before calling. Most yards will run the volume calculation for you and will flag when stepping up to a larger load actually lowers the price per unit.

Ordering and delivery

Confirm the delivery radius and fee early in the call. Two yards quoting similar material prices can land very differently once haulage is added.

Check where the truck can actually dump. Tandem trucks need overhead clearance and firm ground, and most drivers will not reverse across a soft lawn or a new driveway. If access is tight, ask whether they run a smaller truck or can leave the load at the kerb.

Best time to buy in Delaware

Demand for landscape materials peaks from spring through early summer across Delaware, when yards run their longest queues and hold firmest on price. Late summer and autumn typically bring shorter waits and more negotiating room, particularly on larger loads. If your project timing is flexible, buying outside the spring rush is the single easiest way to reduce the delivered cost.
