Wildfires were headline news in 2023, including the Lahaina, Hawaii fire and scores of fires across Canada and Nebraska. It’s comfortable to think a devastating wildfire can’t happen in your area, but it’s better to be aware of the possibility and be prepared. Learn the aspects of Fire Smart Landscaping including creating a defensible space, planning ahead for a fire event, and management of the surrounding landscapes to decrease potential fire damage.  

I often hear from vegetable or flower gardeners who are unhappy with their soil quality. They routinely incorporate organic matter in the soil each fall, but are still disappointed with their heavy soil. Why aren’t they developing beautiful crumbly dark brown soil that’s easy to plant and great for vegetable root crops? Routinely tilling your garden soil each fall and spring could be the culprit.

Mulch is very important to the overall health of our plants, but are all mulches created equal? Some may have more benefits than others and some may not be as helpful as we think they are. Benefits of Mulch Mulch, when properly applied, can provide a lot of great benefits to our plants, including:

Many Nebraska soils have high clay and silt content making them prone to compaction. Foot traffic from both human and pets, equipment and vehicles are all common causes of soil compaction. Look for the following as signs of potential soil compaction in your landscape.

Plant roots grow in soil pore spaces. Pore spaces are also where oxygen is found. Just as plant roots cannot grow without water, they cannot grow without oxygen. Soil pore space is important to plant growth and efficient water use. Soils with good structure have adequate pore space making them well drained while still having good water and nutrient holding capacity. Ideal soils have 50 percent soil particles and 50 percent pore space. An important aspect of good soil structure is soil aggregation.

Join us on March 5, 2021 for the Nebraska Virtual Green Infrastructure Tour!  We will re-visit communities across Nebraska to higlight green infrastructure projects and programs, both large and small.

Soils with good structure and those that not compacted help expand root systems. Roots hold soil in place to reduce erosion, a leading cause of water pollution. Soils that are not compacted allow for increased infiltration of rain and irrigation water. Soil management is important to healthy plants and healthy ecosystems. Following are a few tips for improving residential landscape and garden soils and why it is important for root systems and plant health.

Rain gardens are an aesthetic feature of your residential landscape that also has a hydrologic function. Hydrologic means related to water. A properly designed and constructed rain garden for a residential landscape (no underground drainage system) is designed like a bathtub to hold water and let it slowly seep into the soil beneath the garden. This water is available for plant growth, and this water is removed from runoff that leaves your yard and does not contribute to downstream flooding or pollution.  How well does your rain garden serve its hydrologic function?

Rivers and streams are complex. They are filled with a dizzying array of life, from relatively simple bacteria and algae to more complex forms such as plants, insects, and fish. When everything is working well, rivers provide many benefits to society, including fishing and other recreation opportunities, drinking water, irrigation, and transportation. However, there are also many ways that people can disrupt the natural functioning of rivers. For example, it may be necessary for cities to build systems that rapidly remove rain water to prevent flooding damage to homes and businesses.

Join us, as we tour some of the newest stormwater management projects in Omaha and re-visit established green infrastructure projects. Six of this year’s tour stops are new to the tour! Criteria for tour stop selection included ensuring a variety of consultants, various project scales, various management practices, and availability of tour guides. Tour stops will include:

Permeable pavers let water pass through the spaces between them which are often filled with small gravel or sand.

You can reduce water runoff from your yard by planting a rain garden. A rain garden is a small depression planted to flowers and ornamental grasses. It is designed to temporarily hold and soak in rain water from a roof, driveway or open area. A rain garden is not a pond or wetland. It is dry most of the time and holds water after a rain. Water collected in the rain garden slowly soaks into the soil and disappears in less than 48 hours.

Landscapes which are sustainably designed, installed and managed conserve water, lower the rate and volume of runoff water from rain, snowmelt and irrigation, and help reduce the amount of pollutants reaching surface water. Water related benefits achieved with sustainable residential, business, and community landscapes include:

What is stormwater? It's water from rain or melting snow. Watch the video and learn about rain water runoff and why it can be a problem.
