SURVEILLANCE CONTINUES FOR WALNUT TWIG BEETLES IN NEBRASKA
The Nebraska Department of Agriculture (NDA) will begin another year of surveillance work for the walnut twig beetle (WTB). The beetle, combined
with the fungus it carries, causes thousand cankers disease (TCD) in walnut trees and was discovered in Scotts Bluff County during last year’s
surveillance work.
The WTB is native to North America and is the only insect presently known to transmit the fungus that causes TCD. The disease disrupts the flow
of water and nutrients, ultimately causing the infected walnut tree to die. Early symptoms are yellowing of leaves and foliage thinning of the upper
crown of the tree. Trees usually die within three years after initial symptoms are observed.
PLANT NATIVE: BLACK CHERRY
Black cherry, with its spreading limbs and arching branches, is the largest and most important native cherry
for wildlife. It blooms in spring, loaded with small, fragrant white flowers, each clustered together to form a
narrow pendulous raceme. The abundant flowers are very attractive to small native bees and other pollinating
insects. The shiny, dark green leaves turn lively shades of yellow, orange, and red in the fall. The tree produces
copious amounts of small black fruits in the summer, highly prized by many songbirds, and i’s a larval host to a
good number of butterflies and moths. It has a reputation as weedy and aggressive in forest restoration, where
new seedlings can overtake open ground. In the home landscape this tree has not been a problem, however it
might seed around here and there. It is seldom planted in home landscapes, but for gardeners wanting wildlife
habitat, it’s worth planting.
BENEFICIAL LANDSCAPES: SPRING BLOOMS!
No flower is quite so welcome as the first one to open in spring. And fortunately for
gardeners in the midwest, some of them are tough enough to bloom even through
a snow drift. Spring bulbs like snowdrops, squill and crocus are some of the earliest
flowers to open, with daffodils, hyacinths and tulips soon to follow.
There are some wonderful perennials for blossom and color early in the spring also.
Though it will vary according to microclimate, the perennials below begin to bloom in
March or April and are listed generally in order of “appearance.”
PLANT NATIVE: BLACK WALNUT
American black walnut is one of the most valuable
natural forest trees in the U.S. Its fernlike foliage
provides light, airy shade so it’s a great shade trees
for larger properties in areas where the juglone
produced by the tree won’t stunt the growth of
plants beneath it. The flavorful nuts contain more
protein than any other tree nut; its valuable wood
makes beautiful furniture; husks are used to make
natural dyes; and the hard shells are
SPECIALTY CROP GROWERS, PESTICIDE APPLICATORS CAN WORK TOGETHER TO PROTECT SENSITIVE CROPS
Specialty crops, like fruits, vegetables, hops and honey, add value and diversity to Nebraska agriculture, the state’s
number one industry. That’s why the Nebraska Department of Agriculture (NDA) encourages growers and outdoor
pesticide applicators to work together to protect sensitive commercial specialty crops and pollinators from pesticides.
Pesticides include all categories of pest control products such as herbicides, insecticides and fungicides.
“Specialty crops are one way for Nebraska farm and ranch families to diversify and grow their agriculture businesses,” said NDA Director Steve Wellman.
“In order to protect and support specialty crop producers and agriculture in Nebraska, growers and pesticide applicators need to communicate with
one another throughout the planting and growing season to raise awareness of specialty crops and beehives in the area.”

Japanese Beetle Update & Shipping Nursery Stock Out-of-State
Nebraska has numerous counties infested with Japanese beetle (Popillia japonica). As this pest becomes more common across the state, the prevalence
of Japanese beetle has implications for nurseries that ship out of state.
The Nebraska Department of Agriculture (NDA) monitors for Japanese beetle across Nebraska. Based on trapping results, the following counties are
considered infested as of 2020: Adams, Buffalo, Burt, Butler, Cass, Clay, Colfax, Cuming, Dakota,
Dawson, Dodge, Douglas, Fillmore, Furnas, Gage, Hall, Hamilton, Howard, Jefferson, Johnson,
Kearney, Lancaster, Lincoln, Madison, Merrick, Nance, Nemaha, Otoe, Pawnee, Phelps, Pierce,
Platte, Polk, Richardson, Saline, Sarpy, Saunders, Seward, Scotts Bluff, Thayer, Thomas, Thurston,
Washington, Wayne and York.
PLANT NATIVE: BUR OAK
Bur oak is our most common native oak. It’s big and majestic, tough and reliable. This rugged oak is well
suited for the challenges of weather on the Plains with its thick layer of ridged, corky bark and stout, ice-storm
resistant twigs. The rugged, wide spreading branches stand out in winter, accented by frost or snow, and offer
welcome shade on hot summer days. The leathery, fan-shaped leaves help make this picturesque shade tree a
great choice for the landscape. Bur oak is tolerant of a wide range of soils, moisture conditions and the rigors
of urban life. Oaks provide valuable nut forage for a variety of wildlife and no other plant genus supports more
species of butterflies and moths than the oak.
BENEFICIAL LANDSCAPES: Nebraska’s Unique Native Trees
Nebraska, like the rest of the Great Plains, is not well-known for its trees. After the retreat of
the last Ice Age glaciers about 10,000 years ago, grasslands came to dominate the center of the
continent leaving Nebraska only 3% forested at the time of settlement. Someone flying high
above Nebraska now could be forgiven for looking down at the vast quilt-like pattern of farm
fields and prairie and think that the state is devoid of important trees. They would be wrong.

BENEFICIAL LANDSCAPES: Healthy Soil, Healthy Plants
Most gardeners are aware that soil preparation is important in a new landscape with poor or
compacted soil, but when spring fever hits it’s easy to start planting as soon as the weather
warms up. Putting in the time to ready your soil makes a big impact, though, and will make a
difference in the long-term.
Many soils in built areas (around homes, businesses and roads) are compacted “dead” zones
that can make it tough for new plants to establish roots. Making the effort to build and heal your
soil now, before you plant, can prevent major plant loss later on.
PLANT NATIVE: AMERICAN CURRANT
This thornless currant grows naturally in low-lying moist woodlands. Its spring
blossoms are yellow-green and showy with a bell-like shape. The small flowers
are clustered together like dangling 1-3” long earrings, and are of special value to
native bees. The attractive maple-like leaves are food for caterpillars of the Green
Comma Butterfly. The fall color is a lovely red, which usually begins with coloring
of the veins and the leaf margin. The fruit that forms is a small dark purple
berry about a third of an inch in diameter. Black currants are very nutritious,
high in Vitamins A and C, and in potassium, phosphorus, and calcium. In the
landscape this easy-to-grow shrub does best in full sun and moist soil. Shrubs
may show signs of stress in dry, hot sites and become spindly in too much shade.
The selection ‘Riverview’ is a great choice, originally collected from naturally
occurring plants growing along the Big Sioux River in South Dakota.
BENEFICIAL LANDSCAPES: Gardening in the Time of Covid
You know that feeling. That glorious feeling of running your hands through the dirt. Feeling the
earth connect with your body. Nature and you. Happiness and peace of mind overtake you as
you shake off the cares and strife.
It’s not just connecting with nature gardening gives you. It is the feeling of pure creation.
Planting a living entity, aiding its birth, caring for it as it grows to maturity, watching it grow into
a thing of beauty. Creating a life force. Let’s not forget the sweat equity. Gardening is a way to
get your exercise the fun way. Your garden workout aids in creating endorphins, our “feel-good”
chemicals that assist in stress relief.
Ralstonia Wilt in Geraniums
In April, Ralstonia solanacearum race 3 biovar 2 was detected on ‘Pink Flare’ geraniums (Pelargoniums) in a greenhouse in Michigan. These plants had
originally come from Guatemala. USDA APHIS PPQ is working with state departments of agriculture on a multi-state trace-forward effort, attempting
to track all annual geraniums of this variety that had originated from the Guatemala facility. At this time, nearly 400 facilities in at least 39 states
received suspect nursery stock. Stop sale notices have been issued at all facilities and any suspect plants are in the process of being destroyed and
the facilities disinfected. Fortunately, very few plants were shipped into Nebraska, but all nurseries are encouraged to monitor annual geraniums for
symptoms of wilt.
