How can I fix too much sun in backyard?

Alice has to be the expert on hot, living in Texas! Since the area is only 16 x 8 ft I'd suggest one tree, fast - growing for your area.

If that's to long to wait, how about a canopy made of tent canvas? You've seen those commercials for the canopy you crank out and then roll in, so it isn't exposed to so much rain and wind gusts? You could do the same with two poles that you stand up, a machine screw or a hook to insert in the grommet of the tarp at each end. Attaching the other end of the tarp to the covered bar area with heavy-duty hooks would make a 2 minute job of getting shade. I'll bet it gets hot down in Florida, with a day's worth of sun heating that area! Right now in Chicago, we've got a hot baking sun, but probably less humidity. Enjoy your summer, Dee!
