"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."

Joshua Tree Experts is a certified, full service, tree care, lawn care, and pest control firm who are dedicated to creating healthy, beautiful, and pest-free environments for our raving fans (a.k.a. our clients). We offer general tree care services, insect and disease management for shrubs, spotted lantern fly control, lawn fertilizer, crabgrass & weed control, core aeration, free soil testing, exterior and interior pest treatments, targeted treatments for mosquitoes, fleas, and ticks, and much more. Visit us at JoshuaTreeExperts.com or call us today to begin to love where you live! We offer service to both residential and commercial properties. Lehigh Valley: 310 Center Street Stockertown, PA 18083 (610)-365-2200

"Hired Joshua Tree originally in 2019 for a new lawn install. Our yard is small but the dirt was very compacted due to it being new construction so we knew we needed an aeration and seeding to get it started. After a few weather related hiccups that washed the seed away, they actually came back twice over the course of 6 months to touch up/redo areas that were bare. Every single crew member is helpful, knowledgeable, and responsive to all of our questions, concerns, and requests, on the phone and in person. Their treatment reports come instantly via email and are very detailed and thorough. The website is easy to navigate and has a portal to submit questions and requests that get answered promptly. We had such a great experience that we've now hired and prepaid for them to do 2 seasons of lawn treatments and we will continue to do so. The proof is in the pudding; our lawn looks amazing, and we know this because our Ring camera picks up people walking down the street and we can hear them say so. We've been homeowners at different properties for almost 20 years and have used many other lawn companies and Joshua Tree is hands down, the best in the business. Thank you for making our lawn so amazing!"

"On the 24th of January, I paid and signed for a 365 dollar inspection of my house. He set down glue traps and claimed to come the following week for a checkup. The next week, no show and no call. I got a call a couple days later about an appointment and I called and asked to cancel everything I was signed up for. Today I check my bank statements and I have been charged fifty dollars for the past four months without my knowledge or any services performed. I call to cancel AGAIN and get a refund and they are telling me that there is nothing they can do to give me back the 200 dollars they’ve stolen from me. This place is a scam and unprofessional. They will rob you blind and try to justify it. I have not received a call, text or email with any receipts regarding these transactions and I wasn’t even aware that I was on a plan."

Lawn Fertilization and Treatment questions, answered by experts

You can fertilize right after mowing as long as you've collected the clippings. If you leave grass clipping, they can form a mat that prevents the fertilizer from reaching the soil. Plus, grass clippings are rich in nitrogen, so if you leave them and then apply fertilizer, you can end up with too much nitrogen in the soil.

Starting a mowing business can be profitable if you manage your business wisely, calculate costs accurately, and invest in time-efficient, high-quality equipment. With good customer service, you can lock in loyal customers who invest in weekly lawn care services that turn your business into a successful one. 

Lawn care businesses can earn anywhere from $40,000 to over $100,000 per year depending on how you operate, but you’ll need to factor in the cost of equipment to determine your actual profit margins.

While you may see some germination by simply tossing a handful of new seeds on a lawn, you'll have more success by following the proper reseeding or overseeding process step-by-step. Without properly tilling, mowing, amending the soil, and watering your lawn, the new seed could blow away or simply fail to take root.

Yellow patches, poor growth, or widespread weeds indicate a need for treatment. Soil testing can confirm nutritional deficiencies that require intervention.

Chemical herbicides will kill moss permanently. The same goes with bleach water. However, moss can start growing again once a new layer of dirt and debris is caught in your sand in paver joints. Therefore, the problem is not about killing moss permanently, but ensuring effective prevention of moss regrowth.
