You might try mixing some Soil Moist

in with your soil before you plant. I also think I would set up an umbrella or canopy of some sort in the heat of summer. Something to provide shade in the afternoon.
Good luck with it, and let us know how it goes! My daughter grew plants on her balcony in Las Vegas, up until the week she came to visit me, and nobody watered for her and they all fried.
Her plants actually required less watering than mine do here because her nighttime temps were cool.
