Garden beds on Cement!

Gardening on cement?  It CAN BE DONE!  Pretend that the driveway is actually slate, or clay or something else that is impermeable.  

COMPOST THIS! suggests that ANY cement area can become a garden! My outdoor patio--covered in cement-- has become a garden oasis in the city!   Beds only need to be 6 inches deep for most plants!  For details check out Square Foot Gardening: A New Way to Garden in Less Space with Less Work.  Mel Bartholomew suggests setting the bed on soil that hasn't been tilled. 
COMPOST THIS! suggests that urbanites can utilize the many acres of cement we have in the city by making raised beds and placing them directly on cement (no need for a liner). If you want to grow edibles on a driveway that has shared the space with automobiles, you may want to line the bottom of your bed with a plastic liner to keep chemicals from leaching into your soil.  Remember to add nutrients to your soil by adding fertilizer and compost.  Compost your weeds and cuttings!  Check out COMPOST THIS! Low/No Cost DIY, Apartment- sized composter. 
I've found that my plants prefer the room and drainage provided in raised beds versus plastic or terracotta containers.
