Artifical or synthetic grass has changed so much in recent years that it can be difficult to tell your lawn is not real. The buzz words in gardens for the last decade or so have been
'low maintenance'. Fitting an artifical law is just that. It is also a great way to make your propety more saleable in the future and is therefore an investment.
As with anything you get what you pay for. There are cheap products out there with some being made from toxic products and so they will not last very long. However, if you buy a quality product and it is fitted correctly then you should have a virtually maintenance free lawn that looks great all year round. They need to be fitted properly to ensure suitable drainage is provided and so it doesn't lift up.
Just think of the hours that you spend on your lawn each year. Installing an artifical lawn buys you all that time back again. They are also dog (and children) friendly!
If you have an area for the kids trampoline you can get special shock absorbing material to be placed under the artifical lawn for if they fall.
