Is it time for cutting-edge tech to make your mower greener?

Gardeners want to make their grass even greener. As petrol prices rocket and people become ever more conscious of their environmental impact, many are turning to the latest generation of lawnmowers to keep their gardens looking good. While the fronts of our houses are gradually seeing the replacement of petrol cars with electric vehicles, advances in lithium-ion batteries have meant that the trusted back garden mower has also been given a modern overhaul – but at a price. So is it time to replace your current mower with a battery-powered or "robot" version, stick with petrol despite the spiralling costs, or stay plugged in? The length and breadth of your garden will heavily influence what type of machine you need.
