Answer: Regardless of the water restrictions, newly installed perennials need to be watered at least twice a week during the hot weather. While you don't need to let the hose run for any length of time, you do need to pour a gallon or two of water on each plant every 3-4 days until the weather cools off. Don't use any fertilizer now - plants under water stress cannot deal with fertilizer. Wait until next spring when new growth begins, then feed your perennials.
Good luck with your landscape!
