What type of mulch is best for use in my Broccoli planter?

Question

I am trying to keep my broccoli plants from broccoli plants from bolting. I’ve read that a thick layer of mulch will help keep the roots cooler. Is there any particular type of mulch that is best used for this purpose?

Also, how often should Broccoli be watered during excessively hot weather? Normally all of my vegetable garden gets watered twice a day, (early morning and evening, after the sun goes down).
