Green Lawn Fertilizing is the largest locally owned lawn care company in the Philadelphia Tri-State region. We have been listed in the Philadelphia 100 five times years and INC 5000 9 of the last 10 years based on our rapid growth as a family owned business. We owe our tremendous growth as a business to building honest, trustworthy relationships with our customers and employees. Every aspect of our business is focused on our commitment to providing superior customer service and we take great pride in being A rated on Angie’s list as a result. From day one, when our owner, Matt Jesson, founded Green Lawn Fertilizing, our mission was to become a leading independent green industry company by providing a superior customer experience. 20 years later we feel confident that we have achieved that goal as we have overall exemplary online reviews including over 400 A ratings on Angie’s List! We were recognized among all small or medium sized businesses in the region by the Greater Phialdelphia Chamber of Commerce as their "Customer Service Excellence" award winner. We have also been listed as Lawn and Landscape Magazine’s #9 Lawn Care Company in the country. We are also active members of: NALP, NPMA, LCAP, PPMA and Project Evergreen's Green Care for Troops.

"I had written a poor review after getting unsatisfactory answers about an insect control treatment, which was supposed to have been done with one of my weed control visits , but was not listed as done. Within an hour, Joe B, a manager at Green Lawn, called me to apologize and explain why the treatment may not have been correctly recorded in my records. He was apologetic and kind. The fact that he responded so quickly and was so sincere really impressed me. I also have found the technicians (who do the treatments) to be very friendly too. Therefore I’ve upped my rating and intend to use this company again in 2026."

"Juan, his son and the rest of the crew did a great job in repairing and installing a16 foot second wall with column to my patio. They also had to remove half of the pavers to re-level the patio and added pavers to fill-in the 3 feet of bed between the house and the patio on the left side of the steps. They were punctual and very professional. They laid down 4x8 plywood from my front driveway around the back of my house for heavier equipment to protect my grass. My wife and I could not be more pleased with the job that they did and plan to have them back next spring to add some lights to the other wall and columns as we really like the one's that they installed on the new wall."

We are a small town business with down home pricing. We believe in collaborative team work with our customers to ensure they get the product they want along with information they need to be satisfied with their purchase. We believe in educating our customers, so they can make informed decisions about the product they are purchasing. At Fancy Cutz, it's not about making another sale; it's about building a positive relationship with each and everyone of our customers.

"Contacted Fancy Cutz to speak to the owner about problems with 2 Security cameras. Owner did not return the call, instead had one of his employees call back to let us know there were no appointments available for over 3 weeks. I asked the employee why so far down the road, it does not make any sense to have non-functional Security cameras if you can't have service within a reasonable time frame. The only response to that was "we're just very busy, do you want the appointment?" No other option was offered, so I declined the appointment with Fancy Cutz and I called another Company.. Customer care should be a big part of all business relationships."

"I used their service for two seasons, and received 7 treatments plus an Aearation & Overseeing at the end during each season. I must say that their formula works because after the first couple of treatments, my yard went from a dirt pile to sprouting full, very green grass. At the end of the two seasons, most of my yard came in, with the exception of a few bald spots near the garden. I gave them a C for price, because they are on the higher side when compared to other services-particularly the aeration service. I do like that their customer guarantee provides that they will come back out and repeat your last treatment if you aren't satisfied or aren't seeing results, and I've only had to do that twice in two seasons. Unfortunately, if you aren't home to catch the service tech who is treating your lawn, it's almost impossible to get anyone on the phone directly from the office. Calls always go through a central customer service line, and I've never spoken to my service tech, even after leaving a message or two. Which is why I gave them a C on responsiveness."

"It was a rush to get everything done before winter , and was close, but it got done. We were very pleased with the design, plant suggestions for the sun exposure, which respected our likes/dislikes, and with the quality of installation work. The solution to our swampy sump discharge was innovative and subtle in my mind RSC is not the cheapest outfit in LSD but they do great work. This is the second project they have done for us, and if I need another contractor, they'll be in the mix"

Lawn Fertilization and Treatment questions, answered by experts

No, watering dead grass will not bring it back to life. If the grass on your lawn is truly dead, no amount of water will bring it back to life. However, some methods can bring dying grass back to life. Consider aerating, overseeding, or analyzing your soil to get to the root of why the grass is dying. 

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

In most cases, it is worth paying for professional lawn care. DIY lawn maintenance is possible, but it can get extremely time-consuming, especially to make your property look well-maintained. Not only is lawn maintenance time-intensive, but it can also get expensive, even to DIY, especially considering the cost of fuel and maintenance for your lawn care tools. Professional lawn care services average around $100 per service, making it a relatively inexpensive investment, especially for how much time it saves you.

Yes—hiring a professional lawn care company is worth it if you don’t have much free time to devote to lawn care. Lawn care pros will ensure that your lawn receives the vital nutrients it needs to grow and thrive, and you’re guaranteed to have a healthy, beautiful lawn. Aside from that, it’s a convenient service that frees up your time so you can do the things you love and enjoy. 

Water your yard a little more deeply after a drought for about two weeks (while still avoiding overwatering). Continue to water in the early morning hours before 10 a.m. You'll also want to invest in some high-quality fertilizer to get more nutrients to your roots and help them grow back stronger and quicker. Look up your grass and soil type, or do a soil test, to see what type of fertilizer you need.
