Hedgerow Management

Hedgerows are often composed of tree species that will grow into a line of trees if left to their own devices. Trimming is necessary to maintain a bushy and dense hedgerow, however over-trimming can cause a loss of hedgerow over time. Cutting the hedgerow back to the same place every year will inflict stress on the plant which results in the gradual death of the hedge plants. So, it is important to get your trimming right.

Trim your hedgerow incrementally every two or three years and late in winter to allow berry and nut availability for as long as possible. Never trim between March 1st and August 31st as this is bird breeding season. Take a look at ‘Increasing the value of hedges for wildlife with relaxed cutting regime’ (CEH) to find out the best trimming regime for you!

There will become a point when your hedgerow needs rejuvenating which can be done by hedgelaying or coppicing. Both methods involve some sort of cutting at the base of a hedge plant. New growth will begin from the part of the stem that has been cut which results in bushier denser growth close to the ground. You can follow The Adams Hedgerow Management Scale and the Hedgerow Management Cycle to learn when you need to lay or coppice your hedge.

Hedgerow trees are a great feature to have in your hedgerow. They support masses of wildlife, function as sing posts and territory markers and can harbour dead wood habitat in some cases. You could establish a tree in your hedgerow “for free” by letting one of your hedgerow plants grow in to one.

Managing a dense grassy, wildflower margin 2m + wide at the base of your hedgerow will protect their roots, provide overwintering and breeding locations for invertebrates and a sheltered route for animals navigating the hedgerow. If you can, only cut this margin once every five years and late in summer after plants have re-seeded. If scrub starts to develop, tackle the suckers as necessary.
