Measure hedge runs, planting rows, and coverage. Compare spacing, waste, mulch, and material needs easily. Keep every boundary installation estimate clear and accurate today.
This graph shows how plant count changes when spacing changes.
A hedge installation usually looks simple at first. Real planning is not simple. You need the run length, spacing rule, number of rows, site gaps, mulch depth, and a practical waste allowance. This calculator brings those choices together in one place.
It is useful for boundary planting, privacy screening, frontage upgrades, site edging, and small landscape construction work. You can test a dense hedge layout or a looser layout before you order materials. That helps reduce overbuying and last minute shortages.
The calculator estimates effective hedge length after deductions for openings. It then adds any end allowance, calculates plants per row, multiplies by row count, and applies waste. It also estimates bed coverage, mulch volume, compost demand, plant cost, and labor cost.
This makes it easier to compare two different installation approaches. For example, you can test wider spacing with fewer plants, or tighter spacing with faster visual coverage. You can also compare one row against a double row for screening strength and material use.
The result section appears above the form after submission. That placement makes review easier, especially when you want to adjust only one or two inputs and recalculate again.
Effective Hedge Length = (Total Hedge Length − Openings Or Gaps) + (2 × End Allowance)
Plants Per Row = ceil(Effective Hedge Length ÷ Plant Spacing) + 1
Base Plants = Plants Per Row × Planting Rows
Total Plants With Waste = ceil(Base Plants × (1 + Waste Percentage ÷ 100))
Coverage Area = Effective Hedge Length × Bed Width
Mulch Volume = Coverage Area × Mulch Depth
Total Compost = Total Plants With Waste × Compost Per Plant
Estimated Total = Plant Cost Total + Labor Cost Total
| Project | Length | Spacing | Rows | Waste % | Total Plants |
|---|---|---|---|---|---|
| Perimeter Screen A | 20 m | 0.5 m | 1 | 5 | 44 |
| Entrance Border B | 14 m | 0.4 m | 2 | 8 | 82 |
| Boundary Hedge C | 32 m | 0.6 m | 1 | 10 | 61 |
| Double Row Screen D | 18 m | 0.45 m | 2 | 7 | 90 |
Use the mature spread and screening goal. Formal hedges usually need tighter spacing. Informal hedges often use wider spacing. Test a few values here before placing the order.
Linear planting usually starts with a plant near one end and ends with another near the far end. Adding one helps represent both ends of the run.
Yes. Enter all non planted sections in the gaps field. This keeps the effective hedge length realistic and prevents buying too many plants.
Waste can cover replacement stock, damaged plants, measurement tolerance, and small layout changes on site. Many projects include a modest allowance for safety.
Yes. Increase the rows value to two or more. The calculator will multiply the row count and adjust total plant demand automatically.
Mulch volume helps with ordering bulk material, delivery planning, and installation sequencing. It also gives a better total project view than plant count alone.
No. It uses your spacing input. Always confirm final spacing with nursery guidance, project specifications, and the expected mature width of the selected plant.
Yes. After calculation, use the CSV or PDF buttons. They export the result summary so you can share estimates or keep a quick project record.
