I would not recommend using Dr. Green ever. They are worse than an annoying ex that won't quit calling! I used Dr.Green in 2012 after they did a Groupon promotion. The fertilizer and weed control was satisfactory. Since then I have recieved countless unsolicited telemarketing phone calls, mail outs and invoices for services I never ordered. Despite having cancelled the service repeatedly and now having asked more than a dozen times to have my phone number removed from their call list, the annoyance continues. I just received another invoice for 2014 for services I never requested. My advice is avoid them like the plague and use one of their competitors. Check out their rating with the BBB as it documents a lengthy complaint history of everything I have experienced. I wish I would have checked there first. If you cancel the service, keep the email chain and reference number, as they do not stop sending invoices.
