rFonz Super Fonz Lawn Care, LLC
Su pe By Ellen A. Vincent, Clemson University Environmental Landscape Specialist
Alfonso (Fonz) Hernandez began
specializing in lawn maintenance in
1997. He worked for other people
in South Carolina, learning the
combined craft of lawn care and
business management. He and his
wife Angie noticed something about
lawn care companies--they seemed
to be a magnet for employees and
sometimes owners who didn’t
really care about plants or people.
Angie had a background in human
resources and communications, and
had worked for MCI and Sprint
while Fonz possessed a serious work
ethic packed full of accountability
and responsibility. So when they
combined their talents to launch
their own business in 2006, they
already had a business philosophy:
be passionate about the work.
Extend personal care and attention
to details, “do it for love” says Fonz.
They also knew exactly who to
hire: people who are also passionate
about their work.
The first piece of equipment was
a Honda push mower and the
first yard was located in Lake
Keowee. Fonz has grown slowly,
only buying what he can afford
to pay for. Now there is a small
fleet of Toros and a team of four
full time and two seasonal workers.
They serve residential customers in

possible with an understanding of their life history, monitoring methods
and available management tools. This presentation will provide the
audience with information on the life history of scale insects and wood
boring insects (ambrosia beetles, clearwing moths and flathead borers),
the methods in detecting and monitoring their activity, and effective
management tools (e.g. pesticides and cultural control).

GREEN GONE BAD
Green Gone Bad
Featured Ornamental Plant – ELAEAGNUS PUNGENS (Thorny Olive, Silverthorn)
Featured Ornamental Plant: Elaeagnus pungens (Thorny Olive, Silverthorn)
Some exotic ornamental plants behave badly when they escape from the place they
are planted. Infestations of these plants have negative impacts on nature. One of
these plants is Elaeagnus pungens; common name: Thorny Olive or Silverthorn.
Elaeagnus pungens is a dense evergreen shrub in the family
Elaeagnaceae (not a true olive). The native range of Elaeagnus
pungens is Eastern Asia. It was introduced in the U.S. as an
ornamental plant in 1830. It has been frequently planted in
hedgerows and on highway right-of-ways and is also used for
landscaping. It has escaped ornamental plantings and begun to
spread into natural areas in the midlands and coastal plains of
South Carolina. An example of a severe infestation can be seen
at The Audubon Society Wannamaker Preserve on the north side
of Hwy.6, five miles east of Saint Matthews, S.C. A project to
control this infestation is ongoing by members of the Columbia Audubon Society in order to improve
habitats for native birds and restore the native plant community.
Elaeagnus pungens shrubs typically have multiple stems and very dense
branches with long shoots extending from the top. Twigs are brown with
brown scales and hairy when young. The leaves are alternate, oval to
elliptical, with irregular wavy margins and silvery surfaces especially
underneath, 2-4 inches in length and thick. Axillary clusters of small,
sweet-smelling, white to brown flowers develop in the fall. Fruit are
small, red, dotted with small brown scales and develop in the spring.
Thorny Olive resembles two other exotic olives, autumn olive and
Russian olive which also have silvery foliage. It also can take the form of a climbing plant, growing
over and shading out other plants. The name Silverthorn, comes from the thorns on its branches.
Elaeagnus pungens often becomes a problem when it escapes from
planted landscapes into natural areas. Because Thorny Olive is a
fast-growing, weedy ornamental, it can grow and thrive in a variety
of conditions, and can tolerant shade, drought, and salt. Mammals
and birds disperse seed, widening its area of distribution.
Reproduction also occurs via stem sprouts. Silverthorn can spread
and climb into trees, leading to the displacement of native
vegetation. When established, an infestation reduces biodiversity,
wildlife habitat quality, available forage, and native insect life.
It may not be widely known among horticulturalists and
landscapers that this plant can be harmful to natural habitats.
Please consider removing this species from your inventory and
gardens. There are several native shrubs that can be sold and
planted in its place. These include the evergreens Morella
cerifera (wax myrtle), Ilex vomitoria (yaupon holly), Ilex glabra
(inkberry), Ilex opaca (American holly), Baccharis halimifolia
(groundseltree), Osmanthus americanus (wild olive or
devilwood), Kalmia latifolia (mountain laurel), or Leucothoe Escaped plant
fontanesiana (highland doghobble).

One of the most enjoyable and reward-
ing aspects of urban forestry is making the
annual rounds to visit wholesale tree nurser-
ies to select and tag trees for planting. Those
foresters who order a specific list of trees by
phone or through a broker are missing an
opportunity to discover hidden treasures in
the form of tree species or cultivars that are
new or overlooked. One small species that is
well worth the search is Chinese Fringetree,
Chionanthus retusus. Originally introduced
from Asia in 1845, the USDA Hardiness
Zone for this tree ranges from 5 to 9B/10A
While the native Fringetree, Chionanthus
virginicus, may be better known, Chinese
Fringetree has consistently provided supe-
rior performance in Savannah, Georgia. The
southern type of Chinese Fringetree can be
grown as a standard in tree form, with a
mature height and width range of 15 to 25
feet. This superb tree has many desirable
attributes. In the spring it is an absolute
showstopper, displaying an explosion of cas-
cading lacy white blooms on new terminal
shoots as foliage emerges, whereas the native
Fringetree flowers on older wood, prior to
leaf emergence. During the growing season,
rounded leaves are thick and leathery, with a
lustrous dark green color which persists late
into the year, slowly changing to yellow in
December, occasionally even into January.
Chinese Fringetree has proven to be more tol- Licensed Grower of Encore Azalea®
erant of a wider range of site conditions than
traditional ornamentals. It grows well in full
sun to partial shade, can handle occasional
drought or wet feet, has few pest problems,
and can thrive in the heat. One potential
criticism from a management standpoint is
that once established, annual terminal shoot
growth in an optimal location can approach
two feet or more. This can lead to an imbal-
anced crown if uncorrected. Periodic pruning
is necessary to maintain shape and form of
specimen trees; however, the effort is well
worth the reward.
Individual seedling grown Chinese
Fringetrees have a unique character which
makes them a fine choice for use as a speci-
men ornamental. Chionanthus retusus ‘Tokyo
Tower’ is a new introduction from Japan with
a narrow, upright growth habit (15-20’ height
x 5-7’ width) that offers a great option for
those smaller planting spaces that don’t quite
accommodate a larger tree.
