Hedge Plant Calculator
Work out how many hedge plants you need, based on hedge length, plant spacing and number of rows.
How to use the hedge plant calculator
- Enter how many meters of hedge you're planting.
- Enter the desired spacing between each plant, in centimeters.
- Choose whether you're planting in 1 row or 2 staggered rows, and see how many plants you need in total.
How the number of plants is calculated
The calculator works out how many plants fit per meter, and multiplies by the hedge length and number of rows:
Tighter plant spacing gives a thicker, more defined hedge sooner, but costs more since you need more plants. Two staggered rows give a thicker, more solid and light-blocking hedge than a single row, but also roughly double the number of plants needed.
Spacing decides how quickly the hedge closes
Planting densely gives a hedge that closes faster, but the plants also compete harder for water, light and nutrients. They stretch upwards rather than bushing out at the base, and a hedge planted too tightly often ends up thin at the bottom — precisely where you most want density. Slightly wider spacing produces a slower but more even and durable hedge.
The right spacing depends on the species and on how large the plants are when planted. Fast-growing species can be set further apart because they close the gap within a couple of seasons, while slow, dense species such as yew are often planted more tightly. If the hedge is to mark a boundary, it is worth checking local rules on distance to the property line and on maximum height before planting.
Frequently asked questions
How closely should I plant a hedge?
It varies by species, but many common hedge plants are planted with 25–40 cm spacing. Tighter planting gives a thicker hedge sooner, but costs more and can require more pruning over time.
Is it worth planting two rows?
Two staggered rows give a thicker and more solid hedge sooner than a single row, and are common for tall or light-blocking hedges. The downside is that you need roughly double the number of plants.
What time of year should I plant a hedge?
Spring and fall are usually best, when the ground isn't frozen and the plants avoid the harshest summer heat right after planting. Bare-root plants are often planted in fall or early spring.
