Build and Edge a Planting Bed

Job Overview

This chapter qualifies you to lay out, shape, prepare, and edge one planting bed so that it is clearly defined against adjacent lawn or hardscape, holds prepared soil at the correct grade, and provides stable, safe, mower-clear edging. The finished work product is one bed with a marked and approved perimeter, prepared soil, and installed edging that passes inspection for width, curve quality, drainage, edge security, and mowing clearance.

You will review the approved bed shape, plant layout, mature plant size, drainage, edging, and maintenance access; mark and inspect the bed perimeter from primary viewing points; verify clearance from fixed features; cut the bed edge; remove sod and unwanted vegetation within the bed; prepare soil using the methods taught in Chapters 3 through 5; install the specified edging; and inspect and document the completed bed.

This chapter uses the readiness plan from Chapter 1, the site protections from Chapter 2, the tested and amended soil from Chapter 3, the vegetation-clearing methods from Chapter 4, and the grading and drainage work from Chapter 5. The bed produced here becomes the required surface for the fabric-and-mulch work in Chapter 7 and every planting chapter that follows through Chapter 10.

Skills You Will Demonstrate

• LS-031 — Lay out the bed shape from the approved plan and verify it against fixed features and viewing points.
• LS-032 — Cut clean bed edges at the approved depth and angle.
• LS-033 — Prepare planting soil within the laid-out bed using the methods taught in Chapters 3 through 5.
• LS-034 — Install the specified edging material on a stable base, fastened or staked clear of utilities.
• LS-035 — Separate turf from the bed with a clean, maintained edge relationship.
• LS-036 — Inspect bed definition, correcting loose, high, low, or jagged edging before documentation.

Where This Skill Fits

This chapter depends directly on the readiness plan from Chapter 1, the protected work area from Chapter 2, the tested and amended soil from Chapter 3, the cleared vegetation from Chapter 4, and the graded, positively drained surface from Chapter 5. It applies those results to a specific, permanently defined bed shape rather than treating the bed as an assumed given.

The completed, edged bed produced in this chapter is the required surface for Chapter 7's fabric and mulch installation and for the shrub, tree, and perennial planting taught in Chapters 8 through 10. No later planting chapter authorizes work in a bed that has not been laid out, cleared, prepared, and edged under this chapter's standards.

Scope and Intended Use

This chapter covers:

• reviewing the approved bed shape, plant layout, mature plant size, drainage, edging, and maintenance-access plan
• marking the bed perimeter and inspecting curves from primary viewing points
• verifying clearance from foundations, utilities, drains, paths, doors, and equipment
• adjusting curves to avoid narrow mowing strips and inaccessible pockets
• cutting the bed edge at the approved depth and angle
• removing sod and unwanted vegetation within the bed using Chapter 4 methods
• preparing soil within the bed using Chapters 3 through 5
• installing metal, plastic, wood, masonry, stone, or other approved edging on a stable, fastened base
• maintaining the specified relationship between edging, turf, and mulch
• inspecting bed width, curve quality, drainage, soil condition, edge security, and mowing clearance

This chapter does not authorize the learner to:

• mark, cut, stake, or install edging in an area that has not received an approved or conditional readiness decision under Chapter 1, or that has unresolved utility-locating deficiencies
• select a bed shape, edging material, or edging depth that departs from the approved plan without documenting the controlling reason
• fasten or stake edging without confirming utility clearance at the specific fastening or staking location
• proceed to Chapter 7 fabric and mulch work, or any Chapter 8 through 10 planting work, in a bed that has not passed this chapter's inspection

Any bed area showing an unresolved boundary, drainage, or utility deficiency from Chapters 1 through 5 must be corrected and reinspected under the controlling chapter before this chapter's layout and edging work begins.
