Use good soil and you won't have to feed them for a few months. Water them on day where they need it. I watered mine during droughts daily and normally a couple times a week. Don't use ferts until growth slows or clorosis (yellowing leaves) appears around the older growth. If you use good soil and mulch then water shouldn't be a huge problem. Make the plot big as possible (3feet deep and 3 feet wide. This will allow the plants roots to spread out and take a much more intense beating if necessary.
