well, sometimes things die, "just because", its not anybodys fault. and they get pissy when u tell them the warrenty expired, and u will replace them, but u will charge them. i had a different client call and tell me that 3 plants i put in over 2 yrs ago were lookin a little shabby, they "needed to be replaced". when i said ok, let me figure out the price, ill let u know, they were like, o, u r gonna charge me? 4 get it! now, im sure thats the end of that client, and any referels from them. how do u win? without giving out free things. i try to sell them maint after the install, but they wont bite. then, when the stuff doesnt look so great, they complain. i can only guarentee that the plants will LIVE, for 6 months, i cant guarentee that they will thrive if u dont feed them properly,trim and prune at the right time of year, keep the beds weeded etc, u know.
