Project Steps in Order

Landscaping projects succeed when site prep and hardscape come before soil and planting. Doing it out of order — planting first, then grading — means unnecessary damage to new plants and wasted material.

  1. 1
    Design and site assessment: Sketch your layout to scale. Note sun exposure, drainage patterns, slopes, and any existing trees or utilities. Check HOA rules and local codes for fence heights, retaining wall permits, and easements.
  2. 2
    Call 811 before digging: Call 811 or submit a dig-safe request online at least three business days before any excavation. Underground utilities — gas, electric, water, cable — must be marked before any shovel goes in the ground. This is required by law in most states.
  3. 3
    Calculate and order materials: Use the calculators above to get topsoil, mulch, sod, gravel, and block quantities. Order bulk materials (cubic yards) well in advance if delivery is needed — landscaping deliveries can book out one to two weeks during peak season.
  4. 4
    Obtain permits if required: Retaining walls over three to four feet in height typically require a permit and may need engineered drawings. Check with your local building department before starting any wall over 24 inches. Permits can take one to four weeks to process.
  5. 5
    Site prep and clearing: Remove existing vegetation, grass, and debris from work areas. Kill weeds chemically or by solarization a few weeks before if possible. Remove or grind stumps that will be in the path of hardscape or beds.
  6. 6
    Grade for drainage: Soil should slope away from the house at a minimum of one inch per foot for the first six feet. Low spots that collect water need to be filled or addressed with French drains before adding soil or sod. Poor drainage under sod leads to dead spots and disease.
  7. 7
    Install hardscape elements: Build retaining walls, lay path sub-base and pavers, set edging, and install any lighting conduit before adding soil or plants. Use the retaining wall block calculator and gravel calculator for material quantities.
  8. 8
    Spread base layers: Add compacted gravel sub-base (four to six inches) under paths and patio areas. For planting beds, spread and till topsoil to a depth of four to six inches. Use the sand calculator for bedding sand under pavers.
  9. 9
    Lay sod, plant shrubs, and seed: Install sod on graded, moist soil with staggered seams. Plant shrubs and trees at the same depth they grew in containers. Seed bare areas after sod is down. Water new sod daily for two weeks. The sod calculator gives exact pallet and roll counts.
  10. 10
    Mulch, rock, and final touches: Apply two to three inches of mulch in beds, keeping it away from plant stems. Spread landscape rock or decorative gravel in designated areas over landscape fabric. Use the mulch calculator and rock calculator for quantities. Install irrigation heads or soaker hoses before final mulch layer.

Cost Tiers

Landscaping project costs vary significantly by region, project scope, plant selection, and whether you hire contractors or DIY. These tiers describe what each level typically includes — not specific dollar amounts, which vary too widely to be useful without local quotes.

Budget / DIY

Mulching existing beds, spreading topsoil, overseeding a lawn, planting annuals or small shrubs, and adding gravel paths. All materials purchased from a home improvement store or landscape supply. No heavy equipment needed.

Mid-Range

New sod installation, simple retaining wall (under four feet), paver patio or path, planting trees and perennial shrubs, and decorative rock beds. Mix of DIY and professional equipment rental. One to two bulk material deliveries.

High-End / Full Landscaping

Full landscape design by a licensed landscape architect, engineered retaining walls, irrigation system, outdoor lighting, professional grading, sod or hydroseed on large areas, mature tree planting, and ongoing maintenance contracts.

Costs vary significantly by location, contractor availability, and plant selection. Get at least two to three quotes from licensed landscaping contractors before committing to a scope or budget.

Frequently Asked Questions

Do I need a permit for a retaining wall?
Permit requirements for retaining walls vary by municipality and wall height. Many jurisdictions require permits for walls exceeding four feet in height measured from the bottom of the footing. Walls on or near property lines, walls that support a surcharge like a driveway or slope, and walls in flood zones typically always require permits and engineered drawings. Check with your local building department before any excavation.
How much topsoil do I need to cover a lawn?
For overseeding or a light topdressing, apply one to two inches of topsoil over the existing lawn. For a complete lawn installation from scratch, four to six inches of topsoil is the standard recommendation. Use the topsoil calculator on this site to convert your area and desired depth into cubic yards or bags. One cubic yard covers approximately 162 square feet at two inches deep.
How deep should mulch be applied?
Apply mulch two to three inches deep in garden beds and around trees. Avoid piling mulch against plant stems or tree trunks, which can cause rot. A one-inch layer is sufficient for weed suppression on well-established beds. Refreshing existing mulch only requires adding enough to bring the depth back up to two to three inches — you do not need to remove old mulch unless it has become compacted or hydrophobic.
Should I install landscape fabric before mulch or gravel?
Landscape fabric is useful under decorative gravel and rock paths where you want permanent weed suppression without decomposition. Under organic mulch in planting beds, fabric is generally not recommended because it degrades over time, blocks nutrients from reaching soil, and becomes difficult to remove when plants need division. For paths and decorative rock areas, install fabric over compacted gravel base before adding the top layer.
When is the best time of year to lay sod?
For cool-season grasses (Kentucky bluegrass, fescue, ryegrass), the best time is early fall or early spring when temperatures are between 50 and 65 degrees Fahrenheit. For warm-season grasses (Bermuda, zoysia, St. Augustine), late spring through early summer when soil temperatures reach 65 to 70 degrees Fahrenheit is optimal. Avoid laying sod during extreme heat or drought without a reliable irrigation plan. New sod needs daily watering for the first two weeks.
How do I calculate how much gravel I need for a path?
Measure the length and width of your path in feet, then decide on depth — typically two to four inches for a pea gravel path and four to six inches for a structural gravel sub-base. Multiply length x width x depth (in feet) to get cubic feet, then divide by 27 for cubic yards. Use the gravel calculator on this site to get both cubic yard and bag estimates automatically based on your path dimensions.
Can I do a landscaping project myself or do I need a contractor?
Most landscaping work is well within DIY capability: spreading topsoil, laying sod, installing mulch, building simple garden borders, and planting shrubs. Larger retaining walls, irrigation system installation, grading for drainage, tree removal, and anything requiring permits typically benefit from professional help. If soil must be moved more than a few inches across a large area, renting equipment or hiring an excavator is usually faster and safer than doing it by hand.
