What is Hedge Plants?

The Hedge Plants calculation tells you your plants needed from a few simple inputs. The figure you are solving for here is the plants needed.

The Hedge Plants formula

This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:

  • Hedge length — a value measured in m. Example: 10 m.
  • Plant spacing — a value measured in m. Example: 0.5 m.

How to calculate it step by step

  • Write down the hedge length (for example, 10 m).
  • Write down the plant spacing (for example, 0.5 m).
  • Apply the formula above to get your plants needed.
  • Double-check the result with the Hedge Plants Calculator.

Worked examples

Example 1

Input / OutputValue
Hedge length10 m
Plant spacing0.5 m
Plants needed21

With hedge length of 10 m and plant spacing of 0.5 m, the plants needed works out to 21.

Example 2

With hedge length of 20 m and plant spacing of 0.5 m, the plants needed works out to 41.

ResultValue
Plants needed41

Example 3

With hedge length of 5 m and plant spacing of 0.5 m, the plants needed works out to 11.

ResultValue
Plants needed11

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.

Prefer not to do the maths by hand? — the Hedge Plants Calculator does it instantly, for free, with the formula and a worked example built in.
