Mother R, while the weather is warmer and they are growing (young or old) I water regularly, like any other perennial! Although I amended my soil to be faster draining, I still water every other day in the summer. I hope that answers your question. I have found the "chicks" to be quite ready to grow, so I don't baby them much around water, but I do keep them in bright shade, or just some morning sun, rather than full sun!
Cheers
