Create beds over limestone?

[MikeD]

THe previous owner of our home created a limestone parking lot for some unknown reason. We have had a driveway installed and now want to create some beds and plant grass over much of the remaining "parking lot" limestone. Will we have to remove all the limestone or can we add about 4" of topsoil on top of the limestone?

Any help will be much appreciated.

Anything you plant in 4 inches of top soil will die at first hint of hot/dry weather unless you water daily.

I expected to dig holes through the gravel in the bed where I would actually put the plants. I was most curious about the effect the gravel will have on the ph of the soil and will it make it hard to grow plants.

The limestone will have the same long term effect as liming..............

I'd just remove a section around where you are going to place your plants and check for ph conditions on your plants or test the soil occasionally. You might just have to ammend the soil from time to time to nuetralize the effects of the limestone but I wouldn't guess you'd need to too often.

Awesome. Thanks for your help.
