Question
I live in South Florida.  Along both sides of my house I have access to the backyard.  One side is 7 ft wide and the other 10ft. Right now I have 24" x 24" pavers, spaced 6" apart making a walkway down each side.  The problem is that my great idea to put grass between the pavers is not working because the areas do not get direct sunlight. Also the wider side has the air conditioners and pool equipment so it looks   ugly.  I need suggestions on what to do with these areas to make them look more attractive.  There are Areca palms down the fence line on the wider side and a ficus hedge between us and the neighbor on the more narrow side.  We are considering putting river rock to fill in areas.  Please give us any ideas you have.  We will be doing the work ourselves.  Thank you.

Answer
Jan, If it makes you feel better, this is a common problem. Grass does not like too much shade or growing in thin spaces. I suggest you consider planting a slow spreading ground cover such as liriope (monkey grass), mondo grass, or Asiatic jasmine as groundcover. The jasmine will fill in densely after a year or two. The others may take a little longer. Rock would also work. You may ask your local nursery for other ground covers that do well in yore area. There are lots more, you could mix some for seasonal interest or texture changes. Also consider not having stepping stones on both sides. Surely you use one more than the other. Perhaps with the stones gone the grass on one side would be better able to grow.
Best of luck.
