Here are 13 garden bed ideas, from front-yard foundation plantings to raised boxes, each with a rough mulch and cost estimate you can dial in to your space.

The beds everyone sees: along the house, on the corner, at the curb.

Cut the bed edge first, a clean spade edge or steel edging makes even a simple planting look professional.
2 to 3 inches of mulch is the sweet spot: enough to block weeds and hold moisture without smothering roots.
Keep mulch pulled back a couple of inches from stems, trunks and siding, volcano mulching invites rot.
Plant in odd-numbered groups (3s and 5s) and repeat varieties down the bed for a designed, not scattered, look.
For raised beds, 10 to 12 inches of soil depth handles nearly every vegetable.
