Some are perfectly happy to flood their bowling greens with chemicals or pay someone to do it for them.
Even folk who want to do their bit for the environment unquestioningly spend hundreds of pounds every year maintaining a lawn to impress the neighbours.
Fortunately, a third group rightly regard the lawn as an important part of the garden ecosystem and recognise that, after the compost heap, it's the most important and diverse part of the garden environment.
We've been manipulating grass for thousands of years, starting by creating forest clearings, but the Romans took this a step forward by cutting grass with scythes. This back-breaking work continued till 1830, when a Gloucestershire engineer, Edward Budding, invented the lawnmower, with revolving blades on a spindle. As they came in contact with a fixed blade, they neatly scissored off the grass.
This revolutionary tool gave us enormous power. We could use it to produce a hard green area, ideal for a deckchair, football and thousands of living creatures. Or we could create and maintain a perfect uniformly green lawn. Over the past 50 years, a huge lawncare industry has grown up. With mowers, fertilisers, weed killer and grass seeds, it's worth £400 million a year in the UK.
Unlike many plants grass tolerates mowing but weeds such as nettles are killed off if regularly cut, so after a while a patch of weeds and grass will become a lawn of sorts. By stopping grass flowering, mowing encourages stronger leaf growth.
Cutting a lawn regularly leaves you with vast piles of grass clippings. A US study in 1976 found the weight of grass produced by a lawn was almost as heavy as the plant material of a corn field - 1022 grammes of grass per square metre, compared to 1066 grammes of corn. I can't help wondering why some folk need fertilisers.
Perhaps inevitably, other plants have taken advantage of our mowing regimes. The low-growing leaves of several species, such as yarrow, white clover and self-heal, are untouched by a passing mower. A study in 2004 found 159 species in lawns.
This is the time when gardeners have a clear choice for lawns: let an important ecosystem thrive and be a valuable resource for birds, invertebrates, plants, mosses, lichens, worms and soil bacteria; or destroy that fragile web. Do very little to the lawn; or rake, scarify, weed and feed.
Scarifying is one of the most damaging operations. By raking away dead vegetation, you're removing a lot of the substrate that grass-leaf feeders and fungi rely on. Earthworms, nematode worms, fly larvae, and bacteria need and naturally process lawn thatch. In turn, birds - blackbirds, thrushes, robins and pied wagtails - rely on these tiny creatures for food.
Lawns also provide a haven for fungi, mosses, liverworts and lichens. Instead of valuing this diversity, many gardeners lose all sense of proportion when it comes to moss. British gardeners bought a terrifying (to me at least) 3500 tonnes of ferrous sulphate in 2001, an admittedly wet year, mainly in lawn sand, to kill moss. Perhaps these gardeners should appreciate that different moss species thrive in different types of lawn - ones that are wet, acidic, dry or low in nutrients. The only effective way of removing the green, sometimes lush, moss is to change growing conditions for the lawn. If you've got a wet, shady place, go with the flow and plant ferns.
