The Bulletin of the Environmental Horticulture Department

Message from the Chair

Environmental Horticulture has pro-
gressed, expanded and advanced since
the department was established in 1956.
Many great and talented students have
taken our classes. The industry have
participated in our field days, short
courses and extension programs state-
wide. And, gardeners have gained valu-
able information from county agents,
publications and our websites. These
programs were made possible as a result
of a knowledgeable and creative faculty
and staff and the support of the UF/IFAS
administration, the industry and govern-
ment agencies. ALL of these students,
alumni, industry, faculty and staff,
through their own personal commitments
and interest have made Environmental
Horticulture at the University of FLorida/
IFAS a Leader both nationaLLy and interna-
We have moved from a unidimensional
program focused on production tech-
niques to a multifaceted one also con-
cerned with environmental sustainability,
native plant restoration, Landscape man-
agement, urban tree establishment and
maintanence, wildflower seed production
and use, biotechnology, water use effi-
ciency in production and the Landscape,
and invasive plant management. ALL of
these areas have been established
through sound research programs and the
teaching program has been modified to
inform students about new and emerging
issues. And, speaking of teaching, who
would have believed 15 years ago that we
would offer a CoLLege of Agriculture and
Life Sciences degree in Environmental
Horticulture at six Locations in the state
with some of the courses offered simulta-
neously in aLL Locations? The Environmen-
tal Horticulture program has adapted to
meet the needs of the people and indus-

try in FLorida. As we reflect on the past
and Look to the future, what is next? No
doubt, new issues wiLL emerge, new con-
cepts wiLL be developed, and the faculty,
students and industry wiLL adapt for the
betterment of the environment and our
FLorida gardeners. E y

Horticulture is
GROWING again!
In the Latter part of April 2003, a por-
tion of the Environmental Horticulture
Department relocated to newly renovated
facilities on the south side of the UF cam-
pus. Mehrhof HaLL and two nearby Labora-
tory and office buildings, formerly housing
the PouLtry Science Department, were
completely renovated and refurbished.
Mehrhof HaLL (BLdg. 559) now houses the
Center for Consumer and Landscape Horti-
culture as weLL as computer support staff.
The other two facilities are the PLant In
Vitro CuLture, MoLecular Biology and
Micropropagation Teaching Laboratories
(BLdg. 68) and the Horticultural Systemat-
ics Laboratory (BLdg. 550). The move has
increased our usable space and allowed
some vital restructuring of Laboratories to
meet changing programmatic needs. This
move was timed to coincide with major
renovations of W.M. Fifield HaLL that are
scheduled to continue for at least 24
months. Consult our website at http://
hort.ifas.ufl.edu for current faculty and
staff addresses.

University's wordmarks have
been redesigned for the year-
Long commemoration. As part of
the celebration, our department
has designated this edition of the
Environmental Horticulture News
as its Sesquicentennial edition.
The article on page two gives a
brief glimpse of the Long history
of horticulture at this institution.

She University of Florida is observing its sesquicentennial year in 2003. The
wordmarks of the University and all of its major publications have been
changed for this special celebratory year. The Environmental Horticulture Depart-
ment hasn't been a separate department for these 150 years, as it is today; it hasn't been
known by its current name for very long (relatively speaking). The growth of the environmen-
tal horticulture and turfgrass industries have been especially significant over the last three
decades, and during the same period, the UF/IFAS Environmental Horticulture Program has
developed into one of the leading research, teaching and extension programs in the U.S.
today. Horticulture has occupied a variety of Locations in some of the most cherished histori-
cal buildings on the University of FLorida campus. It has been a continuaLLy changing entity, as
has the ever-growing and changing University of FLorida itself. But it is anything but new.
Environmental horticulture has been at the core of the activities and goals of the University of
Florida since its earliest inception. The original building in which horticultural activities were
housed was FLoyd Hall (top Left), originaLLy called the Agriculture Building but Later named for
the doyen of UF horticulture, WiLbur FLoyd (pictured at right), who taught all the horticulture
and botany courses from the beginnings of the Gainesville campus until his retirement in the
Late 1930's.
At some point in the 1940's horticulture was structured into three departments, each with
its own chairman and faculty. One of these focused on teaching, one on research, and one
department's function was extension. The three horticulture departments were combined
into a single horticulture department early in 1956, only to be split four ways Later that year
into Fruit Crops, Vegetable Crops, Ornamental Horticulture, and Food Science and Human
Nutrition. The original faculty of this new Ornamental Horticulture Department is pictured on
page 4. Dr. Tom Sheehan, one of the original faculty members of the department, stiLL an
active emeritus professor, was a major force for the 1980's name change to our department's
current epithet, "Environmental Horticulture." On page 4 are pictured the five chairman
who preceded the current chair, Dr. Terril Nell (see his message and photograph on page 1).

Even though the Department did not exist in its current form per se before 1956, horticut-
tural curricula are part of the earliest University Records. They were also taught in the Florida
Agricultural College (Lake City), one of the two immediate predecessors of the University of
Florida (aLong with the East Florida Seminary in Ocala) that were abolished by legislative act
to create UF in 1905. The 1908 UF catalog Lists six horticulture classes: plant propagation,
otericulture, pomology, plant breeding, greenhouse construction and management, and land-
scape gardening. By 1914, twelve courses were listed, including evolution of cultivated plants,
forest mensuration, three courses about citrus, and truck gardening, aLL of which were sub-
jects important in the predominantly agricultural Florida economy of that era. The University
has grown and diversified tremendously since that time; the "offspring" of the original Horti-
culture Department now occupy many campus buildings and offsite locations in Florida, teach
dozens of courses, including distance education courses throughout the state, and dissemi-
nate valuable information to millions of Florida residents about state-of-the-art techniques
for growing and using plant materials. This growth is phenomenal considering the first Agri-
culture Building (Floyd Hall) housed eight departments in 1929, only one of which was horti-
If the founders of the University had realized what they were creating, they would no
doubt have tried to gather more than the initial 900+ acres they purchased out on the western
fringes of the small town of Gainesville in 1905.

"This institution was founded to assist well-disposed, .
ambitious young men, and young women, in obtaining a
good education. Idlers, triflers, unruly boys, and refractory
girls are not sought. Should such come to us, we will use all
reasonable effort to correct their evil ways......"

Tom Yeager Developing Environmentally
Friendly Best Management Practices i H.
for Horticulture

Environmental quality has become a paramount concern for today's society. Now, more than ever,
this issue has become crucial to agricultural operations because of urban sprawl and the resulting in-
creased contact of urban with agriculturaL areas. Agriculture operations have always used environmen-
taLLy conscious practices, but now, the phrase "BMP's," or "Best Management Practices," is employed.
Producers of nursery and other crops have realized the need to become proactive in their communication
of the beneficial effects of their management practices to society now that society increasingly ques-
tionS what goes on around it.
Dr. Tom Yeager of the Environmental Horticulture Department has been conducting research to devel-
op BMP's for nursery operations for several years now. He is not alone; coLLaboration and financial sup-
port for this research has come from a variety of sources such as the nursery industry, private compa-
nies, Horticultural Research Institute, Water Management Districts, FLorida Department of Environmental
Protection, FLorida Department of Agriculture and Consumer Services, USDA-ARS, UF, and various associa-
tions and endowments. Research has involved a team approach with faculty from Research and Educa-
tion Centers, USDA-ARS, and other disciplines such as Agricultural and Biological Engineering, Food and
Resource Economics, and Soil and Water Science.
In nursery production, a major concern is to minimize nitrogen runoff from excess fertilization. This
runoff contaminates groundwater and eventuaLLy, drinking water. Research has focused on minimizing
fertilization and use of water resources, together with the monitoring of nitrate runoff. Dr. Yeager
stresses that the development of BMP's should avoid assumption, relying instead on sound and thorough
research. His research over the years has included studies of container spacing, irrigation methods,
measuring nitrate runoff, types of plant and multipLant containers, soil media, and interfaces between
growing area and the underlying ground.

2003 Student Trip Destination : Costa Rica

In early May, 31 students, faculty and staff from the statewide Environmental Horti-
culture Department embarked on a ten-day journey to several areas of Costa Rica. The '-
group toured a multitude of sights by bus, beginning with the Lush tropical foliage and
avian Life of the seaside resort town of Punta Leona. The city of Cartago and the Na-
tional Shrine, followed by Linda Vista (BaLL Horticulture) with its impatiens bedding
plant breeding seed production programs, were next. The group spent four days in the
Orosi Valley, an area rich in horticultural operations. They also got an education in
changing ecotypes, vegetation and agricultural operations as they moved from sea Level
to 10,000 ft. to visit the famous Irazu volcano and national park, almost 6000 acres of
primary forest which includes a cloud forest.
Other agriculturaL/horticuLtural operations visited were: Florexpo, a major producer
of cut flowers, bedding plants, and unrooted cuttings of poinsettia and coleus for ship-
ment to Europe and the U.S.; coffee plantations, one of which ships to Starbucks; cut Tais
flower and foliage producer Finca Plantas y Flores Ornamentales; Agricola Sol in La
Tigra (second Largest foliage producer in Costa Rica); and orchid tissue culture propaga-
tor and grower Taisuco de Costa Rica. They also visited Fides North America, a most
impressive company owned by Kirin (Japan), that runs 17 acres of covered greenhouse
space where cuttings of kaLanchoe, chrysanthemum, geranium, New Guinea impatiens,
and fortunia are produced.
A visit to Costa Rica would not be complete without a trip to the Arenal Rainforest,
where the group ascended 240 feet and moved across the top of the tree canopy via zip
Line, viewing tropical foliage as weLL as the bird, butterfly and monkey fauna. The
group's final destination was Tabacon, a Lush 32-acre resort and gardens at the foot of
the Arenal volcano. Tropical trees and foliage bank the volcanic waters which flow
through the entire area into smaLL waterfaLLs and pools where guests soak and relax. It
was a fitting end for ten rigorous days of horticultural exploration. Everyone agreed ".. ,
that Costa Rica was a pleasant destination worth revisiting.

Technology Training Takes

Doctoral Student to Germany
The investigation of plant stress tolerance is a basic study
that wiLL eventuaLLy Lead to the engineering of plants tolerant
to extreme temperatures. Dr. Charles Guy's Laboratory in the
Environmental Horticulture Department has been working with
the much-studied relative of cabbage, Arabidopsis [see the
article on pg. 6 of the Environmental Horticulture News vol.8(1)
(2002)] as a model to understand these processes in plants.
His Laboratory is now integrating two new cutting-edge tech-
nologies known as "pLant microarrays" and "metabolic profiL-
ing," techniques that have been used in the past to study
both plants and animals, to further their understanding of
the complicated mechanisms plants employ when they respond
to heat and cold stresses.
Currently, there are no facilities to study metabolic profiL-
ing in the United States, so a coLLaboration was established
with Dr. Joachim Kopka at the Max
PLanck Institute (MPI) in GoLm, Ger-
many. A doctoral student in Guy's
Laboratory, Fatma KapLan, traveled
to Germany in February to train in
metabolic profiling analysis proce-
dures using gas chromatography mass
spectrometry (GC-MS) techniques.
This coLLaboration wiLL bring cutting-
edge scientific techniques to the Uni-
versity of FLorida and hopefuLLy be a
dynamic methodology in the contin-
ual attempt to improve agriculture.

Orchid Short Course 2003
The 2nd Orchid Production and CuL-
ture short-course took place at the
Morikami Museum Auditorium, in DeLray
Beach, April 5-6. Dr. Wagner Vendrame
from UF's Tropical Research and Educa-
tion Center tailored the program to the
needs of both students and orchid enthu siasts.
Several renowned orchid specialists gave presentations.
Dave Baskin from Kerry's Bromeliads entertained attendees by
comparing wholesale orchid production to a shoe factory; Paul
Martin Brown of the UF Herbarium enlightened the crowd on
wild orchids of North America; Dr. WesLey Higgins and Diana
FoLsom from Marie SeLby Botanical Gardens spoke about or-
chid diversity, and Georgia Tasker, a journalist from the Miami
Herald, gave a broad view of orchids in the news. ALso, Dr.
KimberLy KLock-Moore from Environmental Horticulture at the
Fort Lauderdale REC reviewed orchid nutrition and Drs. Rob-
ert McMiLLan and Catharine Mannion spoke about orchid dis-
eases and orchid pests, respectively.
UF-IFAS students had first priority to register for this one
credit course, which included an enjoyable tour of the beauti-
ful International Orchid Center at the American Orchid Soci-
ety. The Environmental Horticulture Department is extremely
thankful to the Boca Raton Orchid Society for their assistance
in supporting and organizing the short course, which had plen-
ty of positive feedback. Comments were made about its easily
understood form, the usefulness of the AOS tour in showing
active research methods used in orchid production, and new
information passed along about curing orchids of diseases.

Once again, ALumni Career Night was a highlight of the spring semester. The evening program hosted six graduates of the
Environmental Horticulture department who are currently working in some aspect of the "green industry." This year's participants
included Mark Kann ('99)of Meadow Oaks Golf and C.C., Doug Brogan ('95) of The Lawn Enforce-
ment Agency Inc., Joan Bradshaw ('85), City of St. Petersburg Conservation Specialist, David
Ressler ('96), Cherry Lake Tree Farm, Jennifer Norris Bray ('00), RentokiL Interiors, and Whit WiLL-
iams ('00), First Coast HorticuLturaL.
Students and alumni sat down in an open forum after a delicious meal and discussed job
search, interviews, and what to expect once out in the industry. ALumni advised which special
classes to take and how to prepare for the job market. The top two recommendations were "net-
work" and "don't always go for the top paying position, be sure you wiLL be comfortable in the job
you choose." The alumni also visited with faculty and discussed potential job and internship op-
portunities with individual students. Students were pleasantly surprised during this enjoyable
evening at how much helpful information they received. If you would Like to participate in next
year's event please contact Lisa Hall at Lhalt@ifas.ufl.edu.

Internships are a valuable Learning experience and often are
a good starting point for a
career. Many of our students'
internships have resulted in
their employment. Students
must complete at Least two
months at an internship site;
some choose to stay as Long as
a fuLL year, such as Erin Eck-
hardt (Longwood Gardens).

Spring Semester was an especially busy one for the club.
In January, students designed the floral decorations for
the Sesquicentennial CeLebration opening ceremony and
parties as a fundraising event. Later that month, they
attended TPIE in south FLorida, networking with growers
and attending meetings and other events. The club was
awarded Most Outstanding for Community Service at the
University of FLorida for their work with the Alachua
County Youth Fair Horticulture Expo, the City of Gaines-
ville's Dreamers' Garden, and Idylwild ELementary
SchooL's student ButterfLy Garden. Their final fundrais-
ing event included the spring hydrangea sale to earn
funds for the Costa Rica student trip and the annual
Spring Banquet. The elegant Spring Banquet, held at the
Thomas Center, was an evening of great food, fun, and
awards to faculty and students. A special award of ap-
preciation was given to Dr. Dennis McConnell "for his
personal commitment and sincere dedication to the
success of students throughout the years." The semester
ended with 13 club members participating in the Long-
anticipated trip to Costa Rica.

The Turfgrass CLub's spring semester was busy as weLL as
entertaining. At this year's GCSAA convention in AtLanta,
the club made contacts and Let off mid-semester steam.
In the annual UF vs. Lake City golf tournament at HaiLe
PLantation, the UF boys held their own in a close match
that was more friendly than competitive. They also de-
voted time to the Local Boys and Girls CLub by helping
refurbish one of their basebaLL fields. Their big fundrais-
ing event this year was installing a Large Landscape for a
Local homeowner. The club worked diLigently for more
two days to complete the project in time for the home-
owner's party. They got a good taste of working under a
deadline with no flexibility! Congratulations to the new
club president, Bruce Prock, and his newly elected fellow
officers. The semester ended with an end of the year
hog roast, which gave spotlight to some of the best bar-
beques ever eaten thanks to both Jim Spratt and Dr.
Jerry Sartain.

Hobby Greenhouses

A smaLL greenhouse can be a relaxing
and useful hobby. It can be used to grow
specialty crops such as orchids, germi-
nate seeds and root cuttings for the
outdoor garden, and grow vegetables out
of season. A carefuLLy chosen and con-
structed greenhouse can be enjoyed year
The first step is to decide whether
you want a homemade or a ready-made
greenhouse. Ready-made greenhouses are
precisely built, and are usuaLLy more
attractive than homemade types, but are
usuaLLy more expensive and don't always
fit your situation. Homemade greenhous-
es can be made from scraps, are there-
fore much cheaper, and can be built to
the size that will fit your particular
Before building or buying a green-
house, select a suitable Location. The
area available wiLL determine the size
and type of greenhouse you wiLL build.
Located the greenhouse for maximum
sunlight, especially in morning, but pref-
erably aLL day. The southern or southeast-
ern exposure is the best. Eastern expo-
sure is the next choice, where morning

sun is available. Next best are southwest
and west, though western exposures wiLL
probably need summer shading. Northern
is poor, except for tropical foliage plants,
African violets and orchids.
Locate the greenhouse near sources of
water, fuel for heating and electricity.
This will substantially reduce building
There are two basic types of green-
houses: attached and freestanding. The
attached greenhouse is built against a
building using the existing structure for
one or more of its sides and has the ad-
vantage of easy access in bad weather. It
is also cheaper to heat because it shares
a wall with your house. The freestanding
greenhouse has more growing space,
costs more initially, and costs more to
The size of a greenhouse is influenced
by available space, Location, intended
use and cost. It should be Large enough to
house plant benches, a work bench and
storage materials. Larger greenhouses are
easier to manage because the tempera-
ture fluctuates very slowly.
Greenhouses are made with glass,
fiberglass, polyethylene, or vinyl cover-
ings. GLass houses are very attractive,
permanent, and expensive. These houses
should be built by a greenhouse manufac-
turer or purchased in a ready-to-assem-
ble package because they are difficult to
Fiberglass is an excellent greenhouse
covering. It is Lightweight, strong and
nearly hail proof, has good Light transmis-
sion and requires only a simple super-
structure for support. Poor grades of
fiberglass wiLL discolor and reduce Light
penetration, so use a grade that is guar-
anteed for 10-20 years. The type covered
with a polyvinyl fluoride film resists
weathering and extends its Life. If you

select fiberglass, choose the clearest
grade and do not use colored fiberglass.
PLastic film is cheap but temporary. It
is Lightweight and has good Light trans-
mission, but in sunlight it deteriorates
rapidly and must be replaced every three
to eight months. UV-resistant polyethyl-
ene is more expensive, but will Last much
Wood, steel or aluminum is used for
the supporting framework of greenhous-
es. Only pressure-treated Lumber or rot-
resistant woods such as redwood and
cypress should be used when building a
wood-frame greenhouse. Steel requires
constant maintenance to prevent rust.
ALuminum is the best material because it
is Lightweight, strong, requires Little
maintenance and will Last many years.
GLass and fiberglass greenhouses
should be built on permanent foundations
which in FLorida, where winters are mild,
can be nothing more than a wooden sill
of 2x6 boards or a six-inch concrete foot-
ing. The foundation should never be
higher than the plant benches and no
higher than 10-15" if plants are to be
grown on the ground.Plastic greenhouses
can be placed on the ground.
Before buying or building a green-
house, give careful thought to the size,
style and kind of control desired. Learn
about the problems of people who have
greenhouses and check Local building
codes and zoning Laws before you start
