"Ron and his assistant arrived on time to do some fall cleanup landscaping at my house. What would have taken me three days to do, plus hauling away the debris, took them under two hours. It was the very best money I ever spent - more so because I got to meet such lovely people, but also because they helped me a great deal. I will be calling them in the spring for a clean up and masonry work."

"White Garden Designs is the Best!! I have used him for at least 10 years now and nobody cares more or is more detail oriented than Charlie. I have recommended him and his company to dozens of friends and everyone was as pleased as I am. They always show up on time and if there is ever a problem (which I haven't had) they will always make it right. He takes pride in his work and it shows. He also is a Koi pond specialist, designing and maintenance. This man does it all. He is the go to guy for all your landscaping and pond needs."

"Jorge and crew from Greenscape Lawn Care provided excellent customer service including prompt & friendly communication, fair and upfront pricing, & efficient completion of the project. Jorge listened to my vision and was dedicated to making my vision to come to life. He provided quick digital mockups of my design using pictures of my space. It was the best way to determine the details of my design preferences. The team provided helpful feedback of my design through the whole process. Their quality of work is gold standard, they do not cut corners on any detail. Their work ethic is excellent and their dedication to a projects success is apparent at every step of the process. We are so happy with our new space and receive compliments on it daily from our neighbors and friends."

Landscaping FAQs, answered by experts

Many people have used old tires in gardens as raised beds, planters, tree rings, and DIY decor. However, these uses are not recommended due to the toxicity of many of the chemicals used to manufacture tires. These chemicals can leach into the soil and water as the tire breaks down, creating environmental pollution and health hazards for gardeners and their families.

Pavers are one of the most affordable methods of creating an elevated outdoor space. Gravel is an equally affordable alternative. If your budget permits, you can look into building a permeable driveway to ensure proper drainage. Grid pavers, pervious concrete, brick, and brick pavement are all effective materials. Permeable driveways are great options, especially if you live in an area with heavy rainstorms.

Lakefront landscaping offers benefits such as enhancing aesthetic appeal, increasing property value, supporting ecological balance, and providing recreational opportunities while preserving the shoreline's natural beauty.

Unless it only rains once in a blue moon where you live, you’re going to want water-loving plants in your garden bed or pot. A few ideas for plants that aren’t super fast-growing (meaning they’re good in pots or near foundations) and can handle a lot of standing water include: 

  • Acorus (Sweet flag)

  • Colocasia esculenta (Taro or elephant ear): In many climates, these are annuals, making them less desirable because you need to adjust the chain again after each replant.

  • Equisetum scirpoides (Dwarf horsetail rush): non-dwarf varieties of horsetail are fast growers and can take over quickly.

  • Juncus effusus (Curly rush)

  • Osmunda regalis (Royal fern): Royal fern can grow quickly but can also handle being crowded, making them good container plants.

Grass is the most popular and safest option for planting over a septic drain field, but you can also plant small flowering plants and other lightweight plants that don’t have woody or deep roots. Avoid trees and bushes within 10 feet of the field, as the woody roots can crack the perforated pipes. You should also avoid planting vegetable or fruit gardens over your drain field, as a leak from the pipes could contaminate the soil and put anyone who eats the produce at risk.
