yes, pots need to be shaded or kept out of direct sunlight. like jack said, it's best to get them into the ground as roots don't take heat very well. it's hot out here too and we have to water twice/day now...soon to be 3x/day once the heat of august arrives! and you have some nice bushes there which will require more water as they grow. i've found giving them less more times/day is better for them in high heat areas than just soaking them once or twice a day.
