Garden and yard math without plant prices or landscaper quotes: mulch and gravel volume, raised bed soil fill, plants per bed from spacing, seed from area × packet rate, and rainwater barrel yield from roof catchment. Cross-link construction tools for shared area math. Estimates only — follow seed packets and local harvesting rules.
