Ya know, soaker hoses don't cost all that much... they're under $12 at my local big box store for a 50' hose, under $10 for a 25' flat hose. I bought several in early spring and placed them in my various islands and then mulched over them. Now when I need to water those islands, I just haul the hose over, attach it to the end of the soaker, and I'm done. Easiest watering I've ever done.
