by Movie star gardeners have been throwing down the gardening gloves and stamping up and down on the parterre. The uproar is all about rewilding – the way it can not, should not, mustn’t apply to gardening.
Rewilding gardens is “puritanical nonsense”, rails Monty Don. Alan Titchmarsh believes gardeners have been “brainwashed”. He’s simply written to the Lords about it. The rewilding craze, he advised friends, is an “ill-considered development” loaded with “deceptive propaganda” that can “deplete our gardens of their botanical riches” and be “catastrophic” for wildlife.
What’s irritating about this outburst is that neither have grasped what rewilding a backyard really means. There’s a typical false impression that it’s about doing nothing, “letting nature take over”. However turning your again on a backyard, as each Don and Titchmarsh clearly perceive, just isn’t the way in which to enhance it for wildlife. Thuggish pioneer vegetation take over and, finally, colonising timber shade out the sunshine for different vegetation. Lack of plant range results in lack of insect range and abundance of different life. A backyard is just advanced and species-rich due to the interventions of the gardener.
So, the rewilding gardener just isn’t saying, stand again and let all of it go. Fairly the opposite. It’s solely on the wilderness finish of the rewilding spectrum – in huge areas akin to Alaska, with absolutely functioning ecosystems and apex predators – that human beings can calm down and let nature get on with it. Virtually all the remainder of the land on our planet is already managed, indirectly, by people. In our depleted, fragmented, developed and polluted world, with so many species misplaced and one million extra on the point of extinction, human beings should intervene, in various levels, to revive the pure processes which can be the fount of life.
At landscape-scale, this would possibly imply reviving dynamic river methods and reintroducing keystone species akin to beavers, bison and water buffaloes which, themselves, assist re-establish wetlands, soil and vegetation. At smaller scale, akin to our 3,500-acre rewilding venture at Knepp, in West Sussex, there are apparent constraints. We use outdated breeds of domesticated cattle, pigs and ponies as proxies for the aurochs, tarpan and wild boar that after roamed right here. Their disturbance creates a kaleidoscope of habitats that’s rocket gasoline for wildlife. Within the absence of apex predators, our primary intervention is controlling herbivore numbers to ranges that maximises habitat for wildlife.
At even smaller scale, say, 20 hectares (50 acres) or much less, the place free-roaming animals will not be doable or fascinating, scythes, spades, bulldozers, hedge trimmers and chainsaws can mimic their disturbance. By randomising and ranging the depth of those interventions, as occurs within the wild, the ecosystem of even the smallest rewilding web site can turn into advanced and dynamic.

And so, to the backyard. At a mean measurement of 190 sq metres, but extra intervention is required to create the complexity that produces life. So, the rewilding gardener thinks foremost about how nature works, and acts as a keystone species. This impacts the entire decision-making and design of a backyard.
A traditional gardener, for instance, would possibly construct a pond. Good for wildlife. However it might probably be uniform in depth, spherical, steep-sided and edged with rocks or paving. The rewilding gardener would create a pond with open edges and ranging depths, after which suppose like a beaver – placing lifeless branches within the water to create habitat for aquatic bugs. They could puddle the margins like a water buffalo, creating pockets for aquatic vegetation and locations for newts, frogs and toads to spawn. A miniature ecosystem.
Maybe the best insult to nature in a backyard is the monoculture garden. A nature-friendly gardener would possibly minimize out the herbicides and pesticides, cut back the mowing, encourage garden flowers, and permit rougher areas of lengthy grass as cowl for wildlife. A rewilder will suppose once more. At Knepp, in a backyard redesigned by Tom Stuart-Smith and James Hitchmough, we’ve dumped 400 tonnes of crushed brick and concrete on to a manicured croquet garden. The tough, 3D floor mimics the humps and hollows present in nature, offering microclimates for various communities of vegetation on completely different elements of the slopes.
An ephemeral pond comes and goes with the seasons. We haven’t been purist about natives. We’ve planted 940 species, many from the Mediterranean and southern hemisphere with lengthy flowering seasons that our bugs love. They’re vegetation that love poor, dry soils – that gained’t want fertiliser or watering.
Our gardens, now, should assist us within the battle in opposition to the local weather disaster. The planet is on fireplace. Water is catastrophically scarce. The sprinklers, mowers, leaf-blowers, high-carbon gismos, peat compost and chemical inputs pushedon us by backyard centres – the billion-pound horticultural trade that Titchmarsh has been defending to the Home of Lords – is as dangerous for the planet as industrial farming.
It’s at all times going to be tough, difficult the established conventions and aesthetics of one thing as private as gardening, particularly if it’s your occupation. However the rewilding method might be refreshingly liberating. It may possibly relieve a gardener of the burden of perfection and but nonetheless produce an area that’s achingly stunning. We’d love Don and Titchmarsh to return and see ours: let it converse for itself.
