Can you grow grass over concrete
We have a concrete back garden - I would like to grow grass - if I put down a lot of soil (say 2 inches deep), will grass seeds grow in this?
Everyone thinks I am mad when I ask this question, but cannot see why this is a problem - or does it need to be deeper than 2"?

What is being said is that with only a small amount of topsoil, the area will be totally unsuitable for growing turf, unless the concrete is removed first!
Over a period of time all the nutrients will be washed out of the soil; the roots will have nowhere to go; in summer the ground will dry out very fast and would probably be much the same in winter. Think about how fast water evaporates from concrete even in winter....your lawn would be the same.
If you really want a lawn, the only way to do it is the hard way or by next year all you'll have is a mudbath! Sorry to disappoint you....
It will work great.
For about a week.
When Giants Stadium in East Rutherford, NJ was astro-turf over concrete, they laid sod over it for the soccer championships. What a hard time they had keeping it in decent shape for the duration of the championships! The concrete in Giants Stadium has since been busted up and it is now a grass field.
I agree with Lindy Loo. Perhaps there is a way to ensure proper watering with proper drainage combined with a regimen of careful fertilizing. I imagine it would be a process of trial and error - killing a bunch of grass in the process.
I think breaking up the concrete would be much easier and cheaper in the long run.
First, make a concrete border, so the dirt stays put. At the bottom, there will be drainage holes going thru. then we have just a layer of cardboard for a buffer. Above that, theres a layer of gravel. Then wood chunks or chips. This will help hold in some of the moisture before it goes down into the gravel and out. On top of this probably another layer of cardboard, and then compost or leaves. Then the soil ontop of that. I think this will solve the problems with heat, drainage, and nutrients.
I read in this same article that grass will grow in 1 or 2 inches of soil. I know I had a pile of dirt from sweeping the carport that was an inch tall, and it grew grass on top. It will grow, just needs the other issues taken care of.
I know this is all in theory, but it is crazy enough to work! Worse case senario, I can always plant other stuff if the grass thing doesnt work. Bark chip and raised beds. At least its not concrete! Lol. But don't listen to -it can't be done. I call bs. Good luck! And to me too.
