About a month ago we planted 170 liriope for a customer. Now he is calling complaining that his liriope don't look good. After looking at them about 15-20% of the leaves are browing and appear to be withering away. I don't think this is something to be especially concerned about, and need to meet with him tomorrow. I have been told that cutting back the plants is the first step to take. My brother had a conversation with him today, which consisted of the customer using the f word about 2 dozen times. I don't exactly know what to do. I like to make customers happy, and in 3 years of business have never had to deal with an irate customer. I really feel like telling him that he paid us to plant his liriope, and we did that, and now it is up to him to take care of them. What would you all do? Why do you think the liriope are browning? Is this usual? I have a theory. The liriope were especially bushy when we installed them. I am thinking that the root system has not developed as quickly as the top growth and that is why some of the leaves are browing. Cutting back the top growth should help with this. Does this sound like the right answer to any of you? Any input would be appreciated, as this is the first time I have had to deal with something like this, and as much as this guy has pissed me off, I would still like to take good care of the situation.
