No yearly contracts required for maintenance customers, month to month billing available. OLCB License #9292. Owner and Landscape Contractor: Robert Kinsey. Designer and Office Manager: Sarah Kinsey. Additional email - [email protected]. Award Winning .

"Robert and the team at Artistic Landscapes were so amazing to work with. After my spouse and I fell ill over the summer, we had to let the yard go, and it took us a long time to recover so we never had enough energy to catch up. By the time we called Robert, we felt embarrassed of our yard and anxious to get it resolved. We have struggled in the past getting landscapers to follow through with giving us bids so we were nervous about starting that process again. Other crews that we hired wouldn't complete the job as described and made us feel like we were being difficult for asking questions or speaking up. This was NOT the case with Robert and his team. They were kind, communicative, affordable, flexible and the end product was gorgeous. They promised 100% and gave us 200%. We kept the crew on for monthly maintenance which will ensure that we have a gorgeous yard for years to come. Thanks to Robert, Salvador, Eduardo, Sarah and all of the folks who worked on our project in some way. We are eternally grateful, and feel like proud homeowners again."

Lawn Fertilization and Treatment questions, answered by experts

When hiring a lawn aeration professional, they may suggest other related services to get your lawn looking lush and fabulous. Prior to scheduling any of the following services, you should consult your lawn care pro about the order and timing of multiple projects to ensure best results for your grass. These services might include:

Whether you’re putting down fresh seed or reseeding, there are a few things to keep in mind when seeding your lawn. Be sure to choose the correct seed for your climate, seed at the right time of year, and water two to three times a day for the first week. Generally, Dudley recommends seeding in spring and fall as it is usually cooler and rainier.

Lime isn't a fertilizer. Instead, it helps fertilizers, plant food, and naturally occurring nutrients reach the grass by boosting the pH level in acidic soils. While adding lime isn't a crucial task in some locations, it's vital to keeping a lawn healthy in many areas. Lime's ability to encourage healthy grass by making nutrients in the soil more effective makes the task worth the effort, regardless of location.

Sulfur makes grass greener as it creates a rich, healthy growing environment. It can help reduce the pH level in the soil to ensure the roots can get all the nutrients they need, such as nitrogen, phosphorus, and potassium. Sulfur also makes grass denser, lusher, and stronger. It’s a soil amendment that can make a big difference in the health and appearance of your lawn.

Clover lawns stand up better against dog and cat urine than traditional turfgrass. If your pets love to hang out on the lawn on a sunny day—or if you find yourself with a lot of visiting neighborhood dogs—you could save yourself from yellow and brown patches by making the switch to a clover lawn.
