Why Hedgelaying Makes a Better Hedge
I have to say I love pretty much everything about hedgelaying. I learnt how to lay (or "layer") hedges on a weekend course many years ago. It's something you have to do if you would like to pick it up. The Conservation Volunteers produce an excellent practical handbook, too. My skill levels are pretty basic (!) - I don't lay 100s of metres of hedge every year to practice and I don't have an expert watching over me - but Dorset hedges are pretty simple. Why do I like it so much? To start with there's the connection with that rich rural tradition. Like planting local apple trees. It's genuinely interesting and demanding work too. Even with a chainsaw (not available in 1940s Northamptonshire!) it's taxing and rewarding labour. It makes a much better hedge too.Hawthorn hedge I planted a few years ago. Stockproof it clearly isn't. Lambs etc could cheerfully wander through it. Left unmanaged and you have a series of small trees, which is what many of the common hedge species (like Hawthorn and Blackthorn) want to be.* This has its virtues, but it's not a hedge!
This couldn't matter a row of beans in terms of our hedges - a barbed wire fence protects the garden from rampaging cows. It does matter for other reasons though. Hedgelaying makes for a much thicker, denser hedge with a really solid base. You can see that these young hawthorns, planted around 50cm apart in a standard staggered double row, already look as if they will form a much wider barrier because of the brash I've left on them and the way their stems are lying. Even in its current state it provides a much denser - if much reduced - barrier. It will whistle up in no time, incidentally. We're pretty exposed, so the new hedge will provide a more robust and more substantial windbreak. More than that, though, it will be excellent for wildlife. That's not surprising. Enormous numbers of invertebrates feed on common native hedge plants. In Hawthorn's case it's apparently 149. Its early blossom is a boon for pollinators too, and its berries in autumn for small mammals and birds. These species in turn bring exciting predators. Some insects lay their eggs on hedge plants to overwinter. Pollinators like bees, moths and butterflies enjoy not just spring blossom but also summer flowering hedgerow shrubs like roses and honeysuckle. Managing these plants through laying and then trimming them, rather than flailing, keeps those resources intact.
Hedges can provide fabulous shelter and safe corridors for movement - "wildways". Their value for this is enhanced considerably if they're laid and allowed to breath a little. We're lucky enough to have dormice running around in our mature hedges, and shrews and voles use hedgerows as permanent habitats. Toads and other amphibia and reptiles find their dense, damp cover helpful. Birds are attracted by the insects, berries and nuts that a dense hedge provides, but also benefit from the protection of larger, denser hedges. They're a great substitute for the wood pasture or woodland edge habitat that's so rich in biodiversity.
It's always slightly unnerving to see this kind of reduction but it's something I won't have to do again for up to a decade, and won't take long to look mightily impressive. It's only about 30m long, but should be a lovely and important addition to the garden. Here's one I did a few years ago - pictures at the end of the blog. Hedges regrow incredibly quickly after this kind of treatment, by the way. After a year a hawthorn hedge will send up stems over 6ft tall. Here's the same length 3 months and 15 months after laying:
*In modern times flailing the bottom and surrounds of hedges and using herbicide around them exaggerates this tendency. You end up with a series of plants which look like forks; a single stem supporting a few prongs. Not really a hedge at all. Eventually the forks give up the ghost completely.
