We are Carmelo landscaping LLC. We provide a professional and safe service. Businesses started back in 2012 by Carmelo himself and still working with the crew to help bring the best. We service the Tri state area, mainly Chester County & Delco

"Carmelo and Miguel did a superb job at removing leaves from our yard. We took advantage of the "deal" for 2 hours of work by 2 men, and prioritized the most important areas to focus on. Carmelo and Miguel were terrific, they worked hard to get as much done as possible within the time frame, and were very amenable to focusing on the main areas we requested help with. One thing we did not realize was that the time required to take the leaves to the disposal area needed to come out of the total time allotted, so we weren't able to get everything completed as we had hoped, but the job was well done, and the price paid was worth hiring someone to do it. Definitely would like to employ their service in the future."

"Ended up being a HORRIBLE experience. Never again. Everything started off great. Sign up for service. I was told I'd receive a call the day before the Tech was scheduled to come, and they would service the front and back yards. Fast forward a week, no call from Ned's or Tech, someone just shows up. Guy walks around the house, takes pictures, treats the front yard, and leaves. I call because no one told me he was coming, and he didn't do the backyard. I'm asked to provide proof; unfortunately, my old camera system can't handle a 20-minute download to prove that the customer is not lying. I've been waiting a week to speak to the rep who signed me up, but I haven't received a call. Because the Tech said he completed the work, they believe him. If I could give Zero Stars, I woiuld."

Lawn Fertilization and Treatment questions, answered by experts

First, you should figure out whether you have dormant or dead grass. Dead grass won’t come back, so you’ll have to reseed if you’re hoping for a lush lawn. However, grass can go dormant if it hasn’t received enough water or if temperatures are too cold. If it’s still decently warm outside, you can revive dormant grass by watering it. But if it’s mid-January in New England, for example, you’ll need to wait until the weather warms up again. If you want to keep grass green in winter, consider a grass like Kentucky bluegrass, which maintains its color year-round.

Properly preparing the soil for planting grass seed may include applying fertilizer several weeks before spreading the seed if you plan to overseed the lawn. However, in most cases involving a brand-new lawn, spreading a starter fertilizer along with the grass seed will give it the best chance of taking root quickly and growing strong.

Fast-track your seeds to success by pre-soaking them for 24 hours in a shallow container filled with tap water. The water will penetrate the husk and moisten the embryos inside. After one day of soaking, sow the seeds in the soil. Never soak the seeds for more than one day (unless the specific variety calls for longer), as prolonged soaking could cause them to rot.

The best fertilizer for your lawn contains a balance of the nutrients your grass needs for long-term health. A soil test can tell you the optimum nutrient balance. However, to repair yellow grass quickly, assuming all it needs is fertilizer, apply a nitrogen-rich blend that promotes fast growth.

Sulfur is a secondary nutrient that helps grass grow lush and green. It combines  primary nutrients including nitrogen, phosphorus, and potassium. Sulfur helps the grass absorb nutrients to create a lush, green appearance. While sulfur isn’t necessary for every lawn, it can help most lawns be stronger and greener.
