Key Tips for Reducing Pollutants

Water pollution can come from a variety of sources. Soil, grass clippings, fertilizer, pesticides, paint thinners, and motor oil can pollute water if picked up by stormwater runoff.

Landscape Management Practices

  • Aim downspouts towards planted areas or pervious hardscape and away from impervious paved areas.
  • Collect rainwater from rooftops in rain barrels or cisterns for reuse in landscape irrigation.
  • Amend soil with organic matter. Core aerate lawns to help avoid or reduce soil compaction, increase water infiltration, and promote healthy root systems.
  • Follow University and label recommendations and calibrate spreaders when using fertilizers and pesticides.  Only use these products when needed. Read and follow label directions for all lawn chemicals.

Landscape Design Practices

  • Install rain gardens in locations where they catch and temporarily hold rainwater.
  • Use natural drainage patterns, site grading, berms (planted earth mounds) or other methods to channel rainwater away from impervious surfaces (i.e. pavement) onto planted areas such as grass swales, filter strips, or rain gardens.
  • Plant and maintain healthy plant cover, especially on slopes to stabilize the soil and prevent erosion. Select plants adapted to the site and maintenance level.

How and Why to Separate Turf from Ornamentals

Regardless of the mix, the goal for green minded gardeners is to grow, plant and care for healthy landscape plants and turf. One of the most important factors in the success of these endeavors is getting to know specific needs of the plant material and how they can be combined effectively in a landscape without compromising the needs of each component.

Separate Turf and Ornamentals

Do you have trees growing right in the middle of your lawn? Do you swear under your breath every time you mow, having to trim around them and practice some fancy footwork trying to maneuver the mower around the trunk? If so, perhaps it's time to redesign your landscape, separating the grass and all of the other plants. If you are building a new home, or moving to one with little or no landscaping, you can avoid this maintenance nightmare by simply thinking of turf as a part of the landscape unto itself.

Water Zones

Landscaped Yard

Once good soils are in place, create water zones. Water zones are distinct sections of your property which contain plants with similar water needs. Group ornamentals into H-M-L zones in the landscape. Keep each distinct plant group by themselves – set watering minutes per zone accordingly.

Nutritional Value for the Landscape

Processing lawn clippings and tree leaves into the lawn provides nutritional value as well as reduces waste. Generally, turf clippings contain 6-7% nitrogen, 0.5 to 1.0% phosphorous and 2-4% potassium; when returned to the lawn, they can account for a fourth of the lawn's fertilizer applications each year.
