How do I reduce heat from block wall?
The only convenient place to put my garden is in a corner with one block wall facing east and one facing south. These walls produce so much heat it kills the plants. Any ideas of something I could drape or attach to the wall to help reduce the amount of heat they radiate? I'm in a controlled suburban area so it can't be seen over the wall and it needs to be somewhat temporary so I can remove it without damaging the wall too much. Please help!
