“I like Greenup. They do exactly what they say they're going to do. If you have a question, the individual that's doing your yard at the time will answer them, which is great. They spray my yard with lawn fertilizer and bug killer. I'd give them an A.”

“Greenup does fertilizer for my grass. They deserve an A.”
“It was easy—easy to set it up, and easy to maintain it. They did lawn treatments. I chose them because they were better known. I'll give them an A.”
“So far, so good. They come and do their job, and it seems to work. They just do lawn treatments for me. It was good at the beginning, but because we've had so much dry, hot weather, everything is beginning to turn a bit brown. Greenup came and sprayed, but it's just one of those things that happens here, and I have no complaints about them. They're good. I'd give them an A.”
“They just do lawn treatments, and my grass looks great. My lawn people recommended them to me. I would give them an A.”

“I liked that the service does what they say it's going to do, and my lawn looks great. I'd give them an A.”
“They did everything they said they were going to do, and it has affected my lawn in a significant fashion. I think they said the company was veteran owned, and that caught my attention. They're an A.”
“They do the job, it seems to work, and they're on time. Right now, the lawn's a little dry, but that's because of the weather—it has nothing to do with Greenup. They put a brochure on my door, and I checked them out and decided to try them. I would say they're an A.”
“Greenup was right on target. There was a terrible drought before they came, but the product they used had my grass feeling like carpet. They were very nice and helpful, and I would definitely give them an A.”
“I like that my yard is green, and they customized how they communicated with me. Greenup has been very honest, and I definitely enjoy it. I'd give them an A+.”
“The lawn seems to be getting better; it was in pretty poor shape, and I think what they've done has definitely helped. I'd give Greenup an A+, without a doubt.”

“They do the lawn, and they treated our bushes that had fungus on them. Their product seems to work, and their technicians are knowledgeable. I sure would recommend them. Their customer service is good. I'd say Greenup is A+.”
“Those guys are doing great. Everything seems to be fine. We're not having any problems with any plants or weeds or anything right now. They come out and leave instructions to let us know what we need to do—if we need to water or something. It's convenient for us. They spray bushes and stuff, and I know they put different things in the yard. They fertilized it, but they do shrubs and things like that, too. I'd recommend them. The grade they get is an A+.”
“Greenup has done a good job—it's green out there. I think they do fertilizing, too. I would recommend them. They're A+.”
“They do a great job, and my yard has never looked better. They fertilize my lawn for me. They do what they're supposed to do, and there's no commotion about it. They come out every two months, I believe. I think I've already recommended them to a friend. I'd give them an A+.”
“Greenup has done work for me in the past. They seem very knowledgeable, and what they've been doing has made our lawn better. They come out to put fertilizer down on my lawn about every six weeks to two months, and I've noticed a change. I would recommend them to a neighbor or a friend. They get an A+.”
“So far, so good—my yard seems to respond after their treatment, so I'm happy. They come out to do fertilizing work for me. Their customer service is fine so far—A+.”
“Greenup shows up when they're supposed to, and they treat the lawn. They come seven times a year. I'd give them an A+.”
“They're prompt, and they stick to the schedule. They come out to fertilize my lawn, and they send flyers when they come. They ask which services I want, but they're not pushing it down my throat—I can choose to do things or not. I've noticed a change since I started using them. The lawn is green, and there are no brown patches or beetles—it's great. I'd recommend Greenup, and I'd give them an A+.”
“I like their friendliness. I like that they're on time and that they explain everything to me. They fertilize the yard—I think they've done it six times. They come out about every six weeks. I would recommend Greenup—they're A+.”
“This is my first year using Greenup. They're always on time, they can do what I ask them to do, and they're very personable. They did a very good job. They did lawn treatments and aeration for me. I really wasn't having a problem with my yard—I just needed some upkeep on it. It looks good. It was nice to get the aeration. I couldn't find anybody to do that, so I was really happy that they did it for me. They've been very prompt and up-to-date with the recurring lawn treatment. I've been really pleased with them. They deserve an A+.”
“Greenup is always on time whenever they come, and they do a good job. They do the backyard, the front yard, and the basic maintenance for the grass. My lawn has improved for sure. I would definitely recommend them—A+.”
“They're prompt and courteous, and they get the work done as requested. They've got a good business model going. They keep the lawn fertilized and green, and if we have any brown patches or any type of fungus or whatever on our shrubs or anything, they come out and fix it. It's taken care of very quickly. I'd give them an A+, for sure.”
“They're very reliable. They fertilize my lawn. If they tell you they're going to be at your place at a certain time, they're very punctual. They either come on time or they come early—I'm not really used to service providers like that. I think Greenup is really great about not trying to upsell you when they come over. They treat your lawn, and if they see a problem, they'll flag it or put it in the report, but I've never felt that I've been upsold on anything. I had a couple of issues with what I thought were ground worms. I asked them about it, and the technician said, 'It's actually not that. You don't need to pay for that. What it is, actually, is that your dog is urinating in that spot constantly.' He's really honest and forthright with his services. I would recommend them. I don't have any complaints with them, so I'll give them an A+.”
“Greenup does fertilizing for me, and they've done a good job. My yard looks good. As far as I'm concerned, they're an A.”
“I think we've been pretty happy with Greenup. I'd give them an A, and I'd recommend them.”
“Greenup works on my yard. They come and fertilize, and the grass is green. They do a good job—I don't have any problems with them. I would recommend them. The customer service is OK. I used to use another company, but I quit them. I went to Greenup, and I'm happy with them. I'd have to say they're doing well.”
“Greenup has done fine. We've been happy with their service.”
“They seem to know what they're doing as far as my yard goes, and I don't have to be home for them to do what they need to do. Some of what they're doing is fertilizing—they're trying to keep my yard healthy. I have noticed a change in my yard's health since I started using them. I would recommend Greenup. They get an A.”
“Greenup does fertilizing. They've improved the look of my yard, and they've been pretty easy to deal with and flexible about when they can come. I would recommend them, and I'd give them an A.”
“They did a great job. They do fertilizer lawn treatments for us. They were on time, and the grass turned out great. They've been out twice, I think. They should be out again soon. I'd say they're an A.”
“They're reliable, the stuff seems to work, and the grass is improving. I like that they make it easy to give them payments over the internet—that makes it convenient. They fertilize every seven or eight weeks. I'd recommend Greenup. They get an A.”
“I like that Greenup doesn't waste my time.”
“I have had no problems at all—I expect to continue using Greenup.”
“I like that they're a small business. They do fertilizing work for me about once a quarter, and I've noticed a difference in my lawn since then. I would recommend them. Greenup gets an A for sure.”
“Greenup does a great job. I like that they show up and do their job. I pay them once, and they come do what they're supposed to do. They are definitely an A.”
“I used a different company for over 20 years, and I got totally fed up with them last year. They changed their system, and I had a lot of trouble with them, so I switched to Greenup. They've been fine.”
“I'm a veteran, and I like that Greenup is a veteran-owned company. They come out once every six months and fertilize my lawn, and they do a great job. I've noticed a significant change since I began using them. I would recommend them, and I'd give them an A. They're really good.”
“Greenup comes out quarterly and fertilizes—so far, so good. I've noticed a change in my lawn, so I'd give them an A.”
“They do a very good job. The lawn looks very good. Greenup gets an A.”
“My yard looks better than it did last year. They come out to fertilize it about every six weeks, I think. I would recommend Greenup—their customer service is good. They leave their information on my door. I'd give them an A.”
“My husband had Greenup at his house, and we have Greenup at our new house. I'd give them an A.”
“We like that Greenup is a local company. They come out to fertilize our lawn once every two months. They come on time, and they always seem to know their stuff. I would recommend them. Actually, we have given their name to a couple of people already. I would say they deserve an A.”
“My lawn is green, so I'd give Greenup an A. I've recommended them.”
“Greenup has done a good job.”
“Greenup is a good company. They take care of my lawn by fertilizing it and everything.”
“They're responsive to email and phone communications. I prefer email because it's easiest for me, and I've found them to be responsive and able to provide the information that I need through email communication. I think they've also done a good job taking care of my yard, but most importantly, I appreciate the good communication that they have. They come out a couple times a year to put fertilizer down and help keep the lawn green. I think it's been working. Greenup deserves an A.”
“They apply a fertilizer treatment to the yard. It's painless, and I've noticed a significant difference—the yard looks a lot greener than the neighbors' yard. I would recommend them. I think they deserve an A.”
“They show up to do lawn treatments when they say they will, and the guy does a good job. They've been out two or three times, and my yard looks better. It takes the work off of me. It's an A for Greenup.”
“Greenup does a chemical fertilizer treatment for my lawn. They're prompt, they do what they say they're going to do, and they're good about leaving notices about what they will do to my lawn in the future. I've noticed a change in my lawn—it looks really healthy. I'd give them an A.”
“They're reliable. My yard looks great, so the outcome was good. Greenup seems like a good company. They do fertilizer and fungus treatment, and they aerate the yard in the spring—they do just about anything except for mowing it. I'd recommend them for sure. They're an A.”
“Greenup does fertilizing treatment for my lawn, and everything's good. I like that they've got chemicals, and they do the work while I sit in here and watch them. They're out where it's hot, but I'm in here where it's cool, and I usually drink a little iced tea. My grass is greener, it grows faster, and it stands up tall. It greets me every morning when I go out to pick up the paper. I would say they do a really good job, and I would recommend them. Greenup gets an A from me.”
“My lawn is improving, and I like that. I've been using them less than a year, I believe. They do fertilizing work every couple of months or so, and I don't have any issues as of yet.”
“Greenup does the yard maintenance, chemical spray, and stuff like that. They come on time, and they call us to tell us if they're not going to be on time. It's better than the other companies that we've used in the past, so that's nice. I would recommend them.”
“The Greenup guys are doing great. They spray bushes and put different things in the yard, and we're not having any problems with weeds or anything right now. They leave instructions and let us know what we need to do—if we need to water or whatever—so it's real easy and convenient for us. They get an A+.”
“Greenup has turned my grass from looking all brown to perfect green. I signed up for their shrubbery and grass service, and they come out once a month. I would definitely recommend them.”
“My yard has never looked better. They come out every two months to fertilize my lawn for me, do a great job, and there's no commotion about it. I'd give them an A+. They've done great.”
“They're prompt, and they stick to the schedule. I've noticed a change—no brown patch and no beetles. It's great. They're A+.”
“They fertilize the lawn and take care of it. They do fertilization, pest control, herbicide, and pretty much everything. We still use them. I would say Greenup gets an A. It's been good.”
“Greenup showed up on time, and they made appointments and kept them. That made them an awful lot better than the competitor in the area with whom we had a uniformly negative experience on that front. At the end of the day, the lawn looks really good. They provide monthly fertilizer treatments and control of fungus and insects as appropriate throughout the year. The lawn is great. I've been using them for six months. A+ would be absolutely outstanding for them.”
“I have lawn maintenance done by Greenup. They do everything—they do full landscaping, and they also mow. I will continue to use them this year. I would rate them an A+.”
“I used Greenup to apply fertilizer. I've been with this company for five years. I have asked them to call me before they come so I can be sure I don't have anybody else working in the yard or on the house, and they're very good about that. They won't come until they actually reach me. I would give Greenup an A+ grade.”
“They fertilize my yard, and it looks greener now. The workers are good. It's not my first time using them, and I chose them because other companies weren't any good. I'd give Greenup an A+ because there are no problems.”
“They did lawn service, shrub fertilizing, and aeration at the beginning of the year. It's somewhere between four and six treatments this year so far. I've noticed an improvement in my yard, so I would continue to use them. I would give them an A+. They've done a good job.”
“I have had a pretty good experience with Greenup. I don't have any complaints. They have been taking care of my front lawn about every quarter. Recently, they did grub spraying to prevent grub insects in the lawn. I have been pretty well satisfied. I do have a service contract with them, and the customer service, when I call in, is great. They have done both chemical and organic treatments for me. The workers are real professional—I don't have any gripes about them. I just wanted to have a reputable company to take care of my lawn, and Greenup is it. They have been very professional about the business. They have been great. A+.”
“I like Greenup. They're simple, and their communication with you on their worksheets is consumer friendly. My lawn isn't green and pretty yet—it takes time. I've been with them for probably five months. The customer service is fine, and I've recommended them already. My neighbor told me about them, and then I told my other neighbor about them. We're all three very pleased with the work. I would give them an A+.”
“Greenup takes care of my trees and shrubs. The quality of the work is fine. They just come whenever to do the shrubs and the trees. I had trouble with other companies, so I just picked Greenup. They're an A+.”
“I've been using them for about a year, and I can tell a difference in my lawn. They come out about every six weeks. They're an A+.”
“My lawn looks pretty good. I've got a little brown spot, but I didn't have it treated. I'll probably hit it next year and get the three-stage treatment that they have for it. But other than that, everything looks great. I have a service contract with them. I went with Greenup because I had a bad experience with another company. I don't have any problems with them, so I'll give them a good recommendation. They get an A+.”
“I've had a good experience with Greenup. They seem to do what they say they're going to do. They are treating some bushes and a couple of small trees that were badly in need. They come out every three months and do it whether I'm here or not, and then they bill me. I started using them around the first of the year. I'd give them an A+. They come out and do the work, and there's no worry as far as I'm concerned.”
“Greenup did some work for me in the past. They do my lawn fertilization and treatment. They follow through, call before they come, and they always show up when they say they're going to. My lawn did look better. Right now, I've got a horrible case of lawn fungus, but I don't think that's their fault. I have a service contract with them, and the last time they came out, it was just routine. They use chemical treatments, but they are aware of children and pets. I would give them an A+. I've been satisfied with the service.”
“I have Greenup for mowing the yard and fertilizing. They're really good. I'd give them an A for maintenance, bugs, and fertilizing.”
“We've had a very good experience with Greenup. I'm very happy with them. They take care of the fertilization and fungal care for the shrubs and lawn. We added a service to take care of a brown patch in the front lawn. Every year we get a brown patch, so they're treating that. They're due to come out tomorrow, as a matter of fact, and follow up. They're very good. Everything is working out well.”
“I think they're a reputable company, and I did notice a difference in my lawn. They use a good product, and the lawn and shrubs appreciate it. I'd give them an A.”
“They're doing lawn treatments for me. I did some research on some different company options, and I chose Greenup because they were local and had good reviews. I have yet to meet one of the technicians because they tend to come during the week when I'm not here. They don't leave a mess behind. I've noticed that it has helped the lawn be a little more lush and full. I'd say they get an A.”
“When they said they would do something, they did it. The company we had before gave us a lot of trouble, and we were very unhappy with them. Greenup does a really good job. They come on a regular basis, and they will call if they offer something special. The lawn looks much better. I'd give them an A.”
