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."

"This man Francisco is a thief. He was purchasing a piece of equipment from us and ended up scamming us! We are out our equipment and hundreds of dollars. This is not an honest person. We gave him multiple opportunities to make it right and he has not done so! Be aware if you choose this company. What a pathetic piece of trash! I hope so badly karma comes his way!"

Lawn Fertilization and Treatment questions, answered by experts

Powdery mildew tends to grow mostly on leafy plants. The mold itself isn’t particularly harmful, except for those who are allergic to mold. However, you should treat it like you’d treat the discovery of any other mold, and get rid of it immediately. Powdery mildew can spread to your home, which can cause expensive damage. 

Fertilizing is optional after dethatching. However, the period immediately after dethatching is generally considered the best time to fertilize your lawn because the thick debris is now gone. As a result, applying water and fertilizer as the final steps of dethatching can help to spur incredible growth.

Custom fertilization considers grass type, soil condition, and climate, optimizing growth and reducing pests or diseases while improving overall landscape aesthetics.

Each season’s climate influences approaches needed for effective suppression.

Too much clover in your lawn can indicate several issues with your soil. Clover can thrive in soils with abnormally high pH, low-cut grass, and low nitrogen. Amending these issues can push clover out for good.

Hardy perennial clover loves the low nitrogen and compact conditions that often come with poor, infertile soils. But other factors also contribute to a clover explosion, including drought conditions, cool temperatures, under fertilization, and over-irrigation. You’ll need to evaluate all these elements when planning to kill off the clover.
