soaker hoses are great aren't they?
we have several of them on timers depending on whether or not they lay in a full sun bed or in a shade garden. im not sure about your daylilies reblooming however. I suppose you may get lucky if you have a reblooming hybrid of some kind. ours never rebloom regardless. its hard to offer advice for someone with completely different weather conditions. its 50 degrees and raining right now in my area. and we haven't even begun to worry about watering yet. most of our summer flowering plants are just now starting to get their buds. as a matter offact, we have a dozen daylilies and only one has any signs of having scapes so far! but it sounds like you've got a handle on it pretty well. the part sun/part shade idea is a good one. especially in scorching conditions. our daylilies only get 3.5 hours of afternoon sun- that's it. and they bloom great for us! so it should work well for you too.
