We decided to start with Tea Rose Row since that's the easiest, just one long line, and the system works but there are some issues. Some of the roses are new and small, but most of them are large, and there are also two large butterfly bushes. The large roses are only wet in a small area in spite of keeping the water on for hours. My thought was to put three emitters for each large rose and two for the butterfly bushes and also a dwarf crape myrtle in that row. How long do most of you keep your system on to adequately water the roses and how many times a week? I'm mainly inquiring of people who live in a similar climate to mine. I'd be grateful for any information since this is all new to us. Our system has a long hose with little hoses branching off to each plant.
