Iplanted several agapanthuses last March and they were beautiful at first. Then a month later I noticed leaves turning yellow. I have an automatic sprinkler system that waters the beds four days a week for 10 minutes. I increased irrigation to every day for two weeks and noticed the plants getting worse. I went back to watering four days a week and fertilizing monthly with the liquid fertilizer, but it did not seem to help. I also had one plant that died, and it looked like root rot. I have a heavy clay soil and want to know if I should dig the plants up dig out of the clay and replace with good soil for drainage or any other suggestions you can give me. And do agapanthuses do well in a location where they get sun most of the day? Tracy

Bottom line, you are simply watering them too much.
