Figuring out the soil cost for your new urban planter boxes involves a few simple calculations and considerations. First, determine the volume of your boxes in cubic feet (Length x Width x Depth). Soil is typically sold by the cubic foot or by the bag, with bags often containing 1-2 cubic feet.
The price varies significantly based on type. Basic topsoil is cheapest, while high-quality potting mixes or raised bed blends with compost cost more, ranging from $5 to $20 per cubic foot. Buying in bulk is cheaper per unit but requires a large order and delivery, ideal for big projects. Bagged soil is more convenient for smaller spaces.
For a standard 4'x2'x1' planter box (8 cubic feet), expect to spend between $40 for basic mix to $160+ for premium organic blends. Remember to factor in delivery fees for bulk orders. Investing in good soil initially promotes healthier plants and better yields, saving money long-term. Start by calculating your total volume, then compare local garden center and landscape supplier prices.
