Your local pro will also offer watering and fertilizer instructions for the months after your application. Make sure you will be available to water it consistently, especially in the first two to three weeks for best results.

The cost of 200 square feet of pea gravel depends on how deep your installation will be. The pea gravel material alone costs between $15 and $75 per cubic yard. You'll need just under two yards to cover 200 square feet to a depth of three inches, for a total cost of between $30 and $150.

Sand is a common sublayer for hardscape features like driveways, paver patios, and more. Most projects that involve sand require a 1-inch layer to promote evenness, drainage, and weight distribution. For further drainage, most projects have a 6-inch minimum layer of gravel beneath the sand. 

Measure the area needing coverage and consult with suppliers on average depth requirements for each material. Calculations often use cubic yards for accuracy and practicality.
