A Guide to Hedge Planting Distances

Measuring distances and aligning rope for digging trench. Planting a Yew Hedge.

Correct Hedge Planting Distances are determined, not by the size of plant you buy, but by the height and density of the hedge you wish to create….

The height of a traditional hedge is generally considered to be 6’ – 8’ (2m -2.5m) – what, in the tables below, we have called ‘Standard’. Of course, many hedging plants are capable of growing far taller and, therefore, of creating much taller hedges. If that is your intention then the planting gap should be increased. The table therefore includes a recommended planting gap for those varieties (in bold) suited to being grown into a taller hedge.

Hedge Planting Distances: Other Considerations

  • Poor Soil and/or Harsh Conditions

If your hedging plants are being placed is in a challenging location, be it poorer soil or a less benign micro-climate, you should reduce the planting gap by up to 10%. This will help compensate for the reduced rate of growth.

Also, if your aim is a particuarly tall hedge – 2.5m+ – then you should take the trouble to properly dig in at least a good half metre of organic matter and other natural soil improvers before planting.

  • Creating a Particuarly Dense Hedge

While the recommended Standard planting distances will create a full, unbroken hedge, reducing the planting distances by no more than10% will create a denser hedge, more quickly. But…

  • …Don’t Get Impatient!

When a hedge is first planted, it will simply look like a very gappy row of individual plants. The temptation can therefore be to ignore the recommended planting distances and place the plants much closer together. Don’t! While it will look more hedge-like at the start, without the space to develop roots etc, the plants will not thrive

  • Planting a Double Row

If you wish to create an especially wide hedge, the distance between the plants in each row remains the same. The second row should be planted in parallel, the same distance apart from the first row that the individual plants are placed from each other.

Plants in the second row should be placed in the middle of the gap of the plants in the first row to create a zig-zag – it’s the same principle of how bricks are laid to create a wall.

Do remember, though, that the wider apart, the stronger the plant but the longer it will take to mesh
