How to Plant a Hedge

Autumn is a good time to plant a new hedge, as it gives the plants the best chance of survival and becoming firmly established. There are three keys to success – soil preparation, planting and aftercare.


Begin the initial groundwork early by preparing the soil in your chosen area. Dig over the ground with a spade or fork, removing all weeds, roots and debris as you go. Add in good quality organic matter as you dig, then leave the ground to settle before planting.

To plant the hedge, rather than digging individual holes it is best to prepare one long trench. Dig a long strip in a single row and mark out the site first, then be sure to add more organic matter to help add nutrients to the roots.

Dig the trench to be one spade’s depth and 1m (3ft) wide, then remove all weeds and loosen the soil. When spacing the plants, try not to plant too closely to allow room to spread and develop. Place each plant slightly proud of the soil and fill in around the roots, then firm in well.

Then, when it comes to aftercare, particularly during the first year, it is vital to help the plant thrive. Do this by adding mulch to keep the roots moist and the soil temperature regulated. This will also help to suppress weeds. Then remember to water regularly throughout the year.

Cobra hedgetrimmer

Cobra Electric Hedgetrimmer – available with 55cm or 60cm cutting length

Evergreen hedges generally grow faster than deciduous so they will need trimming at least once a year – preferably twice. Cobra has a range of electric, petrol and battery hedgetrimmers for when the hedge becomes unruly.

Cobra has two electric models in its range. These are a 55cm blade width and 60cm. For more awkward jobs and trickier hedges there is the LRH40E long reach hedgetrimmer, which has an articulating head and maximum length of 185cm. Alternatively, in the petrol options, there is a 62cm or the long reach model comes with the choice of a Cobra or Kawasaki engine.

The latest additions to our hedgetrimmers are lithium-ion powered for extra cordless convenience. These have options of a 50cm 24volt model (the H5024V) or a 55cm 40 volt (the H5540VZ). The batteries on these are interchangeable with other Cobra products too.

When dealing with hedges it’s important to remember a few key points:

  • It is illegal to disturb nesting birds so it is best to leave pruning until autumn and check the hedge thoroughly for wildlife before cutting
  • Always remember safety comes first when trimming a hedge – never use hedge trimmers in wet conditions
  • Keep any chords untangled and out the way to avoid tripping
  • For extra protection make sure you wear safety goggles and sturdy gloves.
