Question
In the backyard there is a concrete noise barrier wall that goes from 10ft and increases to 20ft high.  It runs the length of a one acre piece of property.  We tried English Ivy - it grew on the other side of the wall facing the expressway where there is sun.  The wall is in the shade. We have to do something to cover that wall.  Any suggestions?

Answer
The English ivy should do ok. Are you saying you tried and it died or that it just didn't grow well? If it died, chances are you didn't give enough water or something along those lines. Ivy is one tuff plant once started but it won't be extremely fast in full shade.It may take a while to get it established with full shade. Depending on where you live you may also try creeping fig. It won't grow too far north though and will suffer frost burns.
You may also try Boston Ivy which is looser than English Ivy and grows well from the mid south to the North US.

Good Luck.
