I hired Perez Nursery to install $8000.oo worth of landscaping in the backyard and pool area of my home. Luis Perez, who supervised the job told me that he would be back to check on the plants and trees after installation to take care of any issues that may come up and provide weed control, etc. After approx. 3 weeks, there were some issues that needed to be taken care of. It took 2 weeks of calling the nursery to get someone to come out. The person that came out did take care of some issues, but said he would return again to adjust the sprinkler system and check on some weeds that were starting to appear. Approx. 90 days later, there is a severe weed problem, 5 plants have died and 5 more appear sick. I have left several messages with the machine at the nursery, spoke to a girl that answers occasionally and she assured me that the issues would be handled. I still, after repeated attempts cannot get Perez Nursery to return a call, come to my home, or follow through with any further product guarantee (1 year) services.
