Broccoli and cabbage aren't good choices for June in Texas. Too hot unless there are some hot weather varieties that I'm not aware of. I vote for more zucchini!
might be pretty difficult to get them going in sandy soil as they do like fairly even moisture to get sprouted. perhaps the burlap bag trick will work for you. get your seed bed prepped and plant the seeds at the recommended depth and then water them in gently (ahem ), wet down some burlap bags and put those over them. a few times a day check to make sure things are still damp and then at the time when you start expecting sprouts check to see if any are poking up. of course you do have to remove the burlap once you start seeing some sprouts - they'd be funny shaped or hard to harvest growing through burlap...
they always grow good for me here. may be it's the woodchips?
