What Bert and Mary Supply supplies

Bulk mulch comes in hardwood, dyed, cedar, cypress and pine bark varieties. Bought loose by the yard it usually costs well under half the per-volume price of bagged mulch at a big-box store, which is why most repeat buyers switch to bulk.

Double-ground hardwood is the common default and knits together well on slopes. Dyed mulch holds colour longer but fades unevenly. Pine bark is lighter and floats, so it travels in heavy rain. Ask how long the pile has been sitting — fresh, hot mulch can burn tender plants.

Aggregate yards carry crushed stone, pea gravel, road base, mason sand, concrete sand and structural fill. Material is graded by particle size, and the correct grade depends entirely on whether you are building a compacted base, a drainage layer or a walking surface.

Because Bert and Mary Supply carries several material lines, it is often possible to combine an order across products — soil, mulch and stone on one truck — rather than paying separate delivery charges to two or three different yards.

How much material you need

Mulch is sold by the cubic yard. A cubic yard of mulch weighs roughly 400–800 lbs, so a pickup can typically manage two to three yards.

As a rough guide: 1 yard covers about 100 sq ft at 3 in; 3 yards covers about 325 sq ft at 3 in; 10 yards covers about 1,080 sq ft at 3 in.

Order slightly over rather than under. Coming up short means a second delivery charge, which almost always costs more than the extra material would have.

Ordering and delivery

Delivery pricing usually keys off distance from the yard, so confirm both the charge to your address and any minimum load before comparing quotes.

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.

Pricing for bulk material is rarely published in full, since it moves with stock and season. The business website may list current products, but a phone call will get you a firm delivered number faster.

Best time to buy in Maryland

Demand for mulch peaks from spring through early summer across Maryland, 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.

Pricing the same material at two or three yards is usually worth the phone calls. Bulk rates move with stock on hand, and delivery radius often decides which supplier is genuinely cheapest to your address.
