Planning a landscape island and wondering what it'll actually cost? We've compiled pricing data from landscaping companies across the US to give you real numbers — not the vague "$500 to $50,000" range you find on most sites.
Quick Answer
| Island Size | DIY Cost | Professional Install |
|---|---|---|
| Small (30 sq ft) | $200–$600 | $600–$1,500 |
| Medium (80 sq ft) | $500–$1,200 | $1,200–$3,000 |
| Large (150+ sq ft) | $1,000–$2,500 | $2,500–$6,000 |
These ranges assume plants + materials + mulch + edging. Professional install adds 40–60% for labor.
Detailed Cost Breakdown
Plants (35–45% of total cost)
Plant costs vary wildly by type and size:
| Plant Type | 1-gallon | 3-gallon | 5-gallon | 15-gallon |
|---|---|---|---|---|
| Perennials | $5–$12 | $12–$20 | — | — |
| Ornamental grasses | $8–$15 | $15–$25 | $25–$40 | — |
| Shrubs | — | $15–$30 | $25–$50 | $50–$100 |
| Ornamental trees | — | — | $40–$80 | $80–$200 |
| Palms | — | — | $50–$150 | $150–$500 |
Money-saving tip: Buy perennials and grasses in 1-gallon pots. They establish faster than plugs and catch up to 3-gallon sizes within one growing season. Save your budget for one quality specimen tree or large shrub as the centerpiece.
Soil & Amendments (10–15%)
| Material | Cost per cubic yard | Medium island needs |
|---|---|---|
| Topsoil | $25–$50 | 3–4 cu yd |
| Compost | $30–$60 | 1–2 cu yd |
| Topsoil/compost blend | $35–$55 | 3–4 cu yd |
Delivery: $50–$100 for bulk materials. Buy soil AND mulch in the same delivery to save a trip charge.
Mulch (5–10%)
| Type | Cost/cu yd | Medium island (2 cu yd) |
|---|---|---|
| Hardwood mulch | $30–$45 | $60–$90 |
| Pine bark | $35–$50 | $70–$100 |
| Cedar mulch | $40–$55 | $80–$110 |

| Rubber mulch | $80–$120 | $160–$240 |
Edging (5–10%)
| Type | Cost per linear foot | 50 ft (medium island) |
|---|---|---|
| Plastic | $0.50–$1.00 | $25–$50 |
| Steel (our pick) | $2.00–$4.00 | $100–$200 |

Labor (40–60% of pro install)
Landscaping labor rates vary significantly by region:
| Region | Hourly rate | Medium island (6–8 hrs) |
|---|---|---|
| Southeast | $35–$50/hr | $280–$400 |
| Midwest | $40–$55/hr | $320–$440 |

| Northeast | $50–$75/hr | $400–$600 |
| West Coast | $55–$85/hr | $440–$680 |
Crew size: Most landscape islands require a 2-person crew for 4–6 hours (small) or 6–10 hours (large).
Cost by Style
Not all styles cost the same. Here's how design choice affects your budget:
| Style | Cost Multiplier | Why |
|---|---|---|
| Desert/Xeriscape | 0.7x | Fewer plants, gravel is cheap |
| Natural/Native | 0.8x | Native plants are cheaper, less edging |
| Cottage | 0.9x | Common plants, simple materials |
| Traditional | 1.0x (baseline) | Standard pricing |
| Modern | 1.2x | Steel edging, specimen plants cost more |
| Tropical | 1.3x | Palms and tropicals are expensive |
Ways to Save
1. Buy small and wait
1-gallon perennials are 1/3 the price of 3-gallon and catch up in one season. You save 50% on plant cost.
2. DIY the prep, hire the planting
The most labor-intensive part is removing sod and building up soil. Do that yourself over a weekend, then hire a landscaper for the skilled work (layout and planting). Saves 30–40% on labor.
3. Phase it
Install the edging, soil, and thriller plant in year 1. Add fillers in year 2 and groundcovers in year 3. Spreads the cost and lets you see what works before committing.

ROI: What's the Return?
The American Society of Landscape Architects estimates that quality landscaping adds 15–20% to home value. A $2,000 landscape island on a $300,000 home can increase value by $5,000–$10,000. That's a 2.5–5x return.
For landscaping companies, offering "design-first" proposals with AI-generated visuals (like Yardcast for Business) increases close rates by 30–40% and average ticket size by 25%.
