I used TruGreen/Chemlawn for three years (my bad) to provide monthly insect prevention and fertilizing services to my centipede lawn. The first year they did a fine job, but their work and diminished after 2006. The technician, on several occasions, was stopped by ME prior to application of LIME. You don't put LIME on centipede. The fertilizer was overdone to the point that the grass died in a large patch right at the street. Customer Service was contacted about this, and responded immediately with several patches of centipede turf - but the soil itself was tainted badly. It took three years for the damage to naturally recover. Consistent hi-dose applications of fertilizers is also bad for this type of dichondra grass. Via telephone solicitors, they offered and planned aeration treatments at the wrong time of year for centipede. When I pointed out this issue to the telephone representative - I got a profound, ignorant silence at the other end. BE WARNED - if you have centipede or any other "out of the ordinary" turf/sod - be very sure that your technician is monitored and is knowledgeable enough to service your lawn. You could (as I did) wind up re-sodding after complete destruction by well intended but undertrained technicians. I followed their watering and maintenance suggestions (regular watering and keep the lawnmower blade high) yet their consistent application of too much fertilizer eventually destroyed my entire centipede lawn. I terminated the contract in 2009.Since termination, I have re-sodded my centipede lawn and will, from now on, maintain it myself.
