Some reasons are obvious. Among them are conserving water, reducing bills and improving the look. However our clients also note that
1) We water artificial grass a lot, but it is still looks dead. Enough is enough.
2) My little dogs bring dirt into the house. It is a nightmare to clean it every day.
3) Without much sunlight, we walk on dirt every winter.
4) You would replace turf too after walking through the yard in dress shoes. I have guests every weekend. This is no longer an option.
5) My gardener is no good. And I hate that noise!
