Has anyone used turf on top of existing concrete? We have a concrete slab around the pool which we are thinking to stone tile over. In order to minimize the cracks and of course a natural look, we like to use turf between tiles.
Question is what to do with a turf drainage?

In theory I hate the use of fake grass (well really fake anything pretending to be something that it is not), however, there are plenty of places where real grass just won’t grow and it is the only alternative. The quality and realism is improving all the time too.

Great to read this very balanced article on using artificial turf.

As a garden designer I could not agree more that it is very useful in specific instances (like the tiny square used in my design in the article above), but that it should absolutely not be used as a matter of routine, and not over large areas. The arguments put forward that it can be more environmentally friendly and lower maintenance than a real lawn are completely wrong.

Whilst some clients do use regular fertilizers and irrigation on their lawns, they are definitely the minority and most lawns, other than mowing regularly are usually left to their own devices. The move to a more relaxed approach with lawns, allowing a few daises and other weeds to grow too, adds to their positive ecological footprint. Recent studies have also shown that contrary to popular belief, a lawn can also sequester a large amount of CO2 and the soil supports a huge range of insects and other soil living creatures that are vital to our ecology..

In contrast to this, artificial turf is an ecological disaster!

Firstly it is manufactured which has a large negative impact. Whilst a number of makers are turning to using recycled plastic to make their products, this is usually not possible for all the components of the turf, so there is still new plastic being made. Also, although a number also say their product is in theory recyclable, due to the mix of plastics and the lack of facilities that can undertake the recycling, this basically never happens. Currently all artificial turf goes into landfill - vast quantities of it, as all of the turfs wear out (often quite quickly for the cheaper ones).

Secondly, in order to lay the turf, the good topsoil is dug out and throw away (more landfill mostly) and is replaced by an aggregate sub-base which gives a firm surface for the artificial turf to be laid upon. So not only do you loose the natural grass environment for nature, but you also loose the healthy living soil that is underneath it, together with all the creatures that live in it and all the CO2 it can sequester. Additionally, because the sub-base is often not as permeable as a good soil and because there is no grass using the rain-water, drainage can be an issue, with water being throw onto other parts of the garden and leading to flooding.

The low maintenance argument is all relative as you still need to look after it to keep it looking and feeling at its best. While you still have to pick up solid dog waste, real grass is self cleaning in the rain and the bacteria in the soil break down waste products and odors. I could go on - it gets very hot in the sun for instance, but hopefully you are getting the message.

So - please think very, very carefully before you coat your garden in plastic for the perceived benefit of a low maintenance and attractive looking lawn. It is neither of those things and it is positively destroying the ecosystems in your garden.
