Pollinators and Their Health

By Kathleen Cue, Nebraska Extension Horticulture Educator

One third of our food supply exists because a pollinator moved pollen from one flower to another. Their quest for nectar and pollen means we reap the benefits by harvesting fruits, vegetables, and legumes. Despite the necessity of pollinators for a reliable food supply for humans, pollinator habitat is in jeopardy because of reduced food sources and chemically-dependent pristine landscapes.

Helping pollinators is a local issue. Gardeners can make a difference for pollinator health by planting more flowers, supplying a water source, reducing the number of insecticides used and leaving a few dandelions and white clover for them to feed on.

Raised Beds around Trees - A Bad Idea for Landscapes

By Kathleen Cue, Nebraska Extension Horticulture Educator

As we plan for our much anticipated outdoor projects this gardening season, let’s discuss the tree-killing practice of building raised beds around trees.  Don’t get me wrong here—I am not talking about planting hosta beneath a tree, I’m talking about building a RAISED bed around a tree. This unfortunate practice leads to many dead trees, often years later when the tree owner no longer connects the tree dying with the creation of the raised bed.

The Hard Truth about Rocks at the Bottom of Planting Containers

By: Kathleen Cue, Nebraska Extension Horticulture Educator

As we get our containers ready for planting our amazing annuals or that coveted tomato plant, conventional “wisdom” dictates we must first add an inch or so of gravel.  Problematic? You bet!   

Rocks in the bottom of containers do not contribute to better draining soils and healthier plants.  Instead plant roots encounter saturated soils that don’t drain efficiently.  It all has to do with something called a perched water table.

Emerald Ash Borer

Emerald Ash Borer—Where Is It In Nebraska and When Should Tree Owners Treat For It?
By Kathleen Cue
Nebraska Extension Horticulture Educator

The much-dreaded emerald ash borer (EAB) was identified in Douglas County in 2016.  Since that time, EAB has been found in several other locations that holds implications for counties in the eastern part of Nebraska.

Infestations of this insect are known to kill ash trees in a relatively short time period—from 3 to 5 years in most cases.  Once an ash tree is dead, the tree quickly becomes brittle and is a threat to nearby homes, vehicles, and yes, people.

Japanese Beetles

Japanese Beetles
By Kathleen Cue
Nebraska Extension Horticulture Educator

With over 300 ornamental and edible plants they like to feed on, Japanese beetles (JB) can quickly become an overwhelming insect in the landscape.  Last year, one gardener brought in his peach so covered in Japanese beetles that it was hard to identify the fruit as a peach!

If you didn’t have Japanese beetles last year, then hurray, you may not get any this year or if you do get them, they will be in such low numbers that hand-picking will take care of the problem.  But if you had JB last year, chances are very good you’ll have them this year, too.

Summer camp brings cattle, history, and STEM to campers

August 2, 2024
A metal fence separated a few boys from a bunch of cattle as they looked at each other. Nodding their heads, the boys agreed it would be nice to take one of the cattle back home with them. The boys were part of the Summer Youth Empowerment Camp, which brought more than 30 children to visit the UNL Panhandle Feedlot and the UNL Panhandle Research Extension and Education Center in Scottsbluff on July 24.
