Dropping Leaves

Anonymous added on August 26, 2015 | Answered

So far so good this record breaking heat wave all summer, but now my Bouganvillea is dropping leaves. We water once a week and it is hanging from the porch joyce facing south. My friend is also having a problem w/dropping leaves but her plant has tiny bug-like holes. Any idea why our plants are dropping leaves? She has the same kind of plant 6 ft. away in full bloom! She has been watering every day! Thanks.
