Lawns, Gardens & Landscapes

Green roofs help manage stormwater by capturing rainfall.

In your lawn is overly shaded and/or has poor drainage, moss may be a problem.  Moss is a fast growing, shallow rooted plant that covers the ground, smothers grass and exhausts food reserves from the soil. When moss appears in a lawn, it is usually because growing conditions for turfgrasses and landscape plants are adverse, usually too little light and air circulation.  Other conditions favorable for moss invasion include soil with poor aeration and percolation, compaction, low fertility and high acidity or alkalinity.

Following are effective strategies for managing lawns during periods of hot and dry weather: 1. Learn to recognize wilting in turf plants. It is relatively easy to recognize wilting on a houseplant. The leaves droop and the stem may wither, and the whole plant may have a “dull” appearance. Because turf plants are much smaller and thinner than houseplants, it is much more difficult to recognize drought stress in turf plants.

Weeds in the lawn will drive us crazy through the whole summer, but don’t forget about them yet. Fall is the best time to treat for broadleaf weeds, even though we don’t notice them as much now because they are done blooming for the year.

As we begin a new year and will soon be thinking about lawns and landscapes, here is a reminder to focus on water. A limited resource we can’t live without. A New Year’s landscape resolution can be to conserve and protect water resources.  Now is a good time to analyze past growing seasons. When the weather was dry, were there plants that needed more frequent irrigation to prevent them from wilting? Could these be replaced with drought tolerant plants?

Planting for Water Savings Spring will be here before we know it, which is very exciting for plant enthusiasts. We can get outside and do some cleanup once it starts to get warm. Don’t get too excited though, winter could still show up for a couple more months. One thing you can do now, though, is plan your garden. Choose Well-Adapted Plants

With a tip of the cap to National Groundwater Awareness Week, which was March 11-17, the landscape and gardening industry must do their part to prevent groundwater and surface water pollution on the properties we manage.

With spring weather finally in the forecast, I get excited thinking about my gardening activities for the summer. One of the things that is always on the front of my mind is watering. Will this be another dry year, a normal year (if Nebraska even has normal), or a wet year.

In the overall “holiday” turf fertilization schedule, where Arbor Day, Memorial Day, Labor Day and Halloween are indicators of good timing for applications to cool season turfgrasses (Kentucky bluegrass, tall fescue, perennial ryegrass), early summer is a key timeframe for encouraging healthy growth.  When growing warm season turf species such as buffalograss and zoysiagrass, Memorial Day is perhaps the most important time to apply fertilizer, perhaps followed by a light 4th of July application if a lawn is thin or in need of recovery.

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?

While we can’t ever control or even predict the weather, it is important to have a plan on how to deliver water to our home gardens during the hot, dry months of the summer. While Nebraska may be the capitol of crop irrigation systems, many home gardeners don’t give quite as much thought about water management and delivery in their home vegetable gardens or landscapes. Aside from reducing water need through some good management practices, delivering water in an efficient and sustainable way is important when planning and planting our home gardens.
