Using Native Plants to Attract Wildlife

By Shawn Banks

My wife, Debbie, loves to sit out on the porch and watch the squirrels chase each other around the yard.  There is this one squirrel she has named Crazy Squirrel, because it plays by itself doing flips, tricks and chasing a stick.  She also enjoys watching the birds coming into the yard to take a bath, catch a worm, or enjoy some seeds or nectar from the many flowers in our yard. 

The squirrels love the mighty oak trees in the front and side yard.  Native oaks like willow oak, white oak and red oak seem to be their favorite haunts running up and down the trunk and jumping from branch to branch.  They also seem to enjoy the neighbors’ pecan and tulip poplar trees.

The birds really go after the berries from the dogwood tree.  Debbie notes that the birds leave the Nandina berries until last and sometimes they don’t even eat those.  The little hummingbirds will come right up to the porch to visit the flowers of the herbaceous plants we have planted up close, even when Debbie is out there watching.  She really likes to watch the redheaded finches fight over the seeds from the purple coneflower.  It is the interaction of all the wildlife together that she enjoys watching.

Native plants (flora) have evolved with the native wildlife (fauna) to be mutually beneficial.  The birds, squirrels, and other animals eat the fruit the plants produce, and deposit the seeds in new locations.  This allows the flora to spread and find new ground to grow on.  The bees, butterflies, other insects, and hummingbirds pollinate the flowers that produce an abundance of nectar.  In each case, both the flora and fauna receive some benefit from each other. 

For more information on using native plants for landscaping including lists of native plants for wildlife, check out one of the Urban Wildlife publications (Landscaping for Wildlife with Native Plants, Managing Backyards and Other Urban Habitats for Birds, Butterflies in your Backyard) or visit the North Carolina Wildflower Preservation Society on the web at http://www.ncwildflower.org .  You can also contact your local office of the N.C. Cooperative Extension Service for copies of the publications or more information.

Goshik: The Beauty Queen

By: Kelley Schroedl, Master Gardener Volunteer

Perhaps on more “most beautiful” lists than another other shrub, Osmanthus heterophyllus ‘Goshiki’ is lovely in all four seasons.  Spring’s growth emerges in soft pinks, oranges, creams, greens, and white.  Summer heat melts away the pink and orange hues leaving marbling and flecks of white and cream on green leaves.  Summer through winter, ‘Goshiki’ foliage adds color and texture to the landscape.

Often called a false holly because of the spiny, evergreen leaves, it lacks pricking power of a true holly.  While softer it is nearly as tough with fewer disease or insect problems.  It is deer resistant, drought tolerant once established, and adaptable to container planting.

In Johnston County, this shrub does best in part shade with fertile, moist soils.  It tolerates full sun, shade and drier soils but the growth rate will be slower and the plant will be shorter.  Having a slow to medium growth rate, ‘Goshiki’ can achieve a mature size of 8 ft. x 8 ft.  While this shrub has dense foliage and a pleasing form if left to grow naturally, it can be pruned to keep it compact.

Add this beauty queen to your garden or landscape to brighten shady corners, form hedges or grace container plantings.  Her performance and appearance are sure to give years of pleasure.  ‘Goshiki’ Osmanthus awaits adoption in garden centers near you.

Armored Scales

Order: Homoptera

Gloomy Scale under microscope

Are your plants wilted, yellow, have curly leaves, cracked bark, and deformed blemishes or discolored halos on the fruit?  These are all symptoms of armored scale injury on ornamental plants. Armored scales destroy plants by inserting a tiny straw-like mouthpart into bark, fruit, or leaves and sucking fluid from these. Armored scales are insects that produce a waxy plate-like cover over their bodies.  They vary in color and are less than 1/8 inch in diameter.

If scales become too numerous, spraying infested plants with horticultural oil on a day when no rain or fog is expected in late winter or early summer should provide good control.   Horticultural oils on deciduous plants are effective in spring or summer.  Scales are often well controlled by natural enemies such as lady beetles, predaceous mites, and small parasitic wasps.

GENERAL UPKEEP

  • Soil SamplingCollect
    soil
    samples for FREE testing,
    so you'll know how
    much
    fertilizer & lime to add.  Test your lawn, flower beds &
    vegetable
    garden.  Testing should be done every 3 years.  The kits are
    available
    at the Cooperative Extension office.
  • Clean up and throw away any diseased plant material
    Do
    not
    throw it in a compost pile.  Leaving infected plant
    material
    (leaves, fruits, nuts)
    on on the ground or plants, provides a source of
    inoculum for re-infection next year.
LAWN CARE

 

  • Fertilize fescue lawns for winter.  The November
    fertilization
    (near Thanksgiving) is the most important one of the year for
    cool-season grasses. The soil is still warm enough to permit the growth
    of strong roots that will enable the grass to withstand next summer's
    baking heat. Use a slow-release fertilizer formulated for turf, and
    apply according to soil test results.

TREES, SHRUBS & ORNAMENTALS

  • Planting ShrubsFall is for
    planting!
    September through early February is
    an ideal time
    to plant deciduous trees/shrubs and perennials. Plant evergreen plants
    from September – November.  The cool weather permits
    establishment of a root system before next year's hot weather. Find
    pictures of recommended planting techniques at: https://www.ces.ncsu.edu/depts/hort/hil/hil-601.html
  • It's time to move shrubs from one place to
    another. https://www.ces.ncsu.edu/brunswick/mastergardener/mg201113.html
  • Mulch shrubs/trees, perennials & herbs after the 1st
    killing
    frost for winter protection. Apply a layer 3" deep. Mulch comparisons
    and general info: https://www.ces.ncsu.edu/depts/hort/hil/hil-608.html
    Daffodils
  • Plant spring flowering bulbs as the weather turns cold.
    For
    best landscape effect, plant groups of bulbs in between shrubs, or
    scatter bulbs in wooded areas; avoid planting bulbs in straight
    lines. 
    Always plant quality bulbs.  Daffodils ,
    Spanish
    Bluebells (Hyacinthoides
    hispanicus), and Snowflakes (Leucojum aestivum) are bulbs to consider.
    By contrast, Tulips and Dutch hyacinths decline after their
    first season and are best treated as annuals. Tips for
    planting/purchasing bulbs at: https://www.ces.ncsu.edu/depts/hort/hil/hil-611.html 
  • Use shredded leaves as mulch.  Fallen leaves contain
    lots
    of nutrients,
    but they decompose slowly. Help the process along by grinding up yourCompost Pile
    leaves rather than sending them to the landfill.  You don't need a
    shredder;
    simply rake the leaves into rows and run them over with a lawnmower.
  • Compost your yard waste! As
    you cut back your perennials
    in
    preparation for winter, think about returning that bounty to your
    garden in the form of compost.  Compost is nature's favorite
    fertilizer
    and soil conditioner.  Recycle grass clippings, leaves, and
    non-diseased
    garden refuse.  For information on how to compost: https://www.ces.ncsu.edu/depts/hort/hil/hil-8100.html
  • Here are some tips on how to protect your plants from cold
    damage
    :https://www.ces.ncsu.edu/depts/hort/hil/hil-604.html 
LANDSCAPE IDEAS



  • Before you put those plants in the ground, consider this ….Landscape
  • Landscape with a plan. A well-thought-out landscape plan
    will produce a
    more "finished" effect.  Analyze your
    property and draw a simple map, noting which areas are sunny, shady,
    moist or dry.  Consider where you need evergreens for screening,
    shorter plants to maintain a view, and about creating a
    landscape that will be appealing throughout all four seasons. 
  • Put the right plant in the right place.  Choose
    plants well suited to the growing
    conditions in your yard.  We can provide many publications
    describing plants
    that
    are
    well-adapted to our county. Master
    Gardener Volunteers, nursery professionals, gardening books geared
    toward North Carolina are also excellent
    resources.
  • Allow space for plants to grow to their mature size. 
    A
    common
    mistake is placing a large or fast-growing plant where there is not
    enough room for its full height and spread.  The error results in
    continuous
    pruning in an attempt to keep the plant to a size nature
    never intended it to be.  Builders and beginning landscapers often
    place
    shrubs too close together, because the plants look so small when they
    come from the nursery.  Find out how large the plant can be
    expected
    to grow, and place them where they can fulfill their potential.
  • Put the garden to bed for the
    winter
    . Pull out all annuals
    that have completed their
    life cycle and cut back perennials.

VEGETABLES & FRUITS

  • HerbsWinterize your herb
    garden
    : https://www.ces.ncsu.edu/depts/hort/hil/hil-8112.html
  • Rototill the vegetable garden
    to
    expose harmful insect
    larvae and
    disease organisms to the cold and predators. You'll be set to plant
    next
    spring instead of
    waiting for the soil to dry out enough for tilling.
