Remove all rubbish from the hedge, including old wire, sheet metal or rails put in to block gaps, tins, bottles and anything else which will interfere with the work and possibly damage the tools.
Preliminary trimming
The amount of work involved will depend on the state of the hedge, and a neglected hedge will need heavier trimming. Firstly cut and pull out as much of the bramble, clematis or other scrambling plants which you can, as these will hinder the laying process. Cut out any elder plants, as these cannot be laid due to the brittleness of the stems. Elder suppresses other plants, and is not a good hedging shrub. Try to remove the stump later. Cutting can be done using a slasher or billhook, though beginners may prefer to use loppers. A small chain saw can also be used by qualified persons.
When using a slasher or billhook, trim as much as possible with an upward stroke. Cut with, rather than directly across the grain of the branches for a neater, easier job.
Trim back the brushy side growth along the near side of the hedge, using a slasher or chain saw. Cut away enough to open up the stems for convenient pleaching and laying, but leave the tops of the trees bushy so that they form an effective barrier when laid. Ideally, trees for laying should be about 12’ (3.6m) high, and can be trimmed on the near side up to a height of about 8’ (2.4m) with the slasher. If the trees are short however, it is best to avoid trimming much off the sides until the trees are laid and in position, so that you can be sure that enough brush is left to make a dense, living barrier.
Remove excess leafmould, deadwood and other material from around the base of the trees to provide a clear cutting area. Hook the material out with a slasher or billhook, or trample it in as convenient.
