The south side of our house is the exterior wall of our garage.
There are no windows, and the edge of the property line is too close to
put a lean to greenhouse or anything like that on there. Last year I
tried establishing a blueberry hedge up pretty close to the house there.
I used peat, coffee grounds, a small amount of aluminum sulfate mixed
in to the soil, plus a slow release acidifier. (soil is rather alkaline
here) I tried watering every day, but there was simply no rain for a
couple of months, and it was so hot and dry. Only 1 or 2 plants made it
out of 6 or 7. I am going to take the healthiest plant and put it in a
pot. This is actually the first time I've tried growing blueberries and
had one live more than 6 months. However, I think that spot would be
better used for something else.

Can anyone suggest something that is heat and light loving, which
could be productive in such a spot? It will essentially get direct
sunlight all day long, and the spot can really concentrate heat from the
sun in spring and fall. Thanks!
