Water consistently, every day in really hot weather, and soak the pot well. If in the ground, water until established, then wean them off slowly. My herbs survive with a good soaking 1-2x's a week in blazing hot weather. Make sure the container or the ground is really well draining. Avoid a lot of fertilizer, your herbs will taste better.
Herbs are also very forgiving once established.
A skipped watering may result in wilted plants, but they'll spring back with renewed zeal. Artemesia and stachys are also considered fuzzy herbs, and I find them in good shape with almost no water at all. The insertion of hydroprills by means of inserting a long spike into the pot and inserting the gell capsules deep might help. So might double potting, using sawdust between the pots. Moving pots will just fry the roots now suddenly exposed to a hotter exposure.
