I bought a 100 square meters artificial grass, but I am stuck in how to lay this huge thing in my garden. Anybody can help?
Find some guy who knows gardening or landscaping, usually they know how to do the job properly.
It is very easy if you buy the right one made of turf, and the supplier will come to door to lay it for you.
I highly recommend you to hire the professionals to do it because a professional can do it properly without wasting your effort too much and provide additional benefits like free site assessments and certain length of warranties afterwards in case there's any problem.
I think you can do it by yourself if you have previous experience with laying the huge carpet by yourself, because they are basically similar.
You can either lay the grass by yourself which can save you money, or hire some professional company to do that for you.
