Receiving a graduate edu-
cation would be much
simpler if students had to
concentrate only on
coursework, tests and
conducting a specific
research program. Today,
many Environmental Horticulture graduate
students are satisfying their course require-
ments of the graduate program on the Gaines-
ville campus. However, unlike a few years
ago, the students are likely to conduct re-
search in Gainesville and at one of our Re-
search and Education Centers during their
degree program these graduate students
have Co-Major Professors in Gainesville and at
a Research and Education Center. Students
must become accustomed to balancing the
professional and academic philosophies of two
faculty members and the need to stay in one
location for three to four months and another

UF/IFAS Hosts First ENH
Science Camp for
Middle School Children
The Mid-Florida Research Et Education Cen-
ter (MREC) in Apopka was abuzz with noise and
laughter June 21st-25th. Although it was UF's
summer break, laboratories and classrooms
were put to use to stimulate interest in Envi-
ronmental Horticulture and associated scienc-
es. Statewide faculty and staff teamed up to
offer a diverse program exposing 21 middle
school children to the following topics:

location for the remainder of the year. Sounds
like the real world multitasking to achieve a
goal! In the case of our graduate students,
they are receiving outstanding academic
knowledge, experience that will guide them
through their professional and personal lives
for many years and the ability to work with our
faculty on- and off-campus. These students
learn the value of communication among peo-
ple at multiple locations and are exposed to a
much larger portion of academic and industry
related experiences than those students who
remain in one location for a degree program.
While these multi-location programs are diffi-
cult, the mentoring and experiences gained by
the students are life changing they truly learn
the value of the strong, coordinated statewide
Environmental Horticulture program within UF/
IFAS. Read more about this
topic on page 2. ....-

The Growing Environment: Exploring the roles
of water conservation and healthy soil. Camp-
ers experimented with several different soil
types defining such terms as porosity and par-
ticulate and witnessing first hand the filtering
effects of each soil type. This exercise was
followed by a discussion on water use, reuse,
and irrigation. Campers made their own sprin-
klers with interchangeable heads to show the
difference between standard irrigation and
micro irrigation. The concepts of flow and
water pressure were topics for discussion at
the dinner table that evening as campers en-
thusiastically shared what they had learned
with their families.

Plant Identification and use: Learning about
plant characteristics and how to best use them
in interior and exterior landscapes. Taking into
consideration the light and water needs of
various plants, campers designed their own
dish gardens. This exercise was most appropri-
ate, as Apopka is known as the "Indoor Foliage
Capitol of the World." It was interesting to
observe campers as they carefully chose a
variety of plants and potting materials that
would function well together and be aestheti-

cally pleasing.

The "Split Personality" of Environmental Horticulture

A new trend is emerging in graduate
study in the Environmental Horticulture
program. Several students who in the
past worked in one location with a single
committee chairperson are now working
with faculty statewide and have two or
more co-chairs serving on their graduate
committees. While the challenge of
distance is a hurdle to overcome, these
students have found that there are real
benefits in being involved in research
throughout the state.

Christopher Cerveny is working with Dr.
Jamie Gibson (Milton) and Dr. Rick Schoe-
llhorn (Gainesville) on his M.S. Chris
comes to us from Michigan State Universi-
ty, where he graduated in 2002 with a BS
in horticulture. His studies focused on
greenhouse floriculture production. After
graduation, Chris applied his talents as a
grower of specialty annuals and perenni-
als in Kalamazoo, Michigan until he real-
ized he wanted to continue his academic
career; this ultimately brought him to

Chris is based in Gainesville during the
academic year and works at our Milton
campus during the summer months.
Working from two locations provides
many challenges for a new graduate
student, but Chris has found ways to
meet these challenges head on and to
enjoy the benefits that it awards. "I see
this system as a potential for other Uni-
versities around the country. Having this
extension experience will assist me expo-
nentially in the future." Chris communi-
cates regularly with his advisor via e-mail
and telephone conversations. Chris will
be studying tropical perennial stock plant
management and cutting performance, so
the distance between his two research
locations provides an excellent model for
simulating long distance shipping practic-
es. "I think this scenario awards me an
opportunity not available elsewhere."

Ellie Danielson earned her B.S. from UF's
School of Forest Resources and Conserva-
tion, majoring in Natural Resource Con-

servation and specializing in Environmen-
tal Education. She is currently working
towards an M.S. in Environmental Horti-
culture with Dr. Sandy Wilson of the
Indian River Research and Education
Center (IRREC) at Ft. Pierce and Dr. Rick
Schoellhorn (Gainesville Campus).
Ellie began her research in Ft. Pierce
and returned to Gainesville in the fall
semester to continue her studies here on
the native blanketflower (Gaillardia
sp). Ellie also has committee members at
the North Florida REC in Quincy and West
Florida REC in Milton.

According to Ellie, "It can be hard to
work with professors in different places.
It takes a lot of mailing to stay in touch,
and LOTS of gas." She also feels she has
the best of both worlds with the advan-
tages of working at different campuses.
"There is more field area for experiments
in Fort Pierce, and a totally different
environment from Gainesville. The cam-
puses have different kinds of equipment
and specialists."
Her research focuses on how wildflow-
ers grown from seeds gathered statewide
perform in different parts of the state,
an aspect of research known as "prove-
nance testing." She will be using field
plots located at the North Florida,
Gainesville, and Ft. Pierce campuses to
grow the flowers. The data from her
study can be used by wildflower growers
and the Florida Department of Transpor-
tation, providing information on the
suitability of blanketflower types for
different locations.
Ellie's advice to anyone traveling
between campuses is: 1) communicate
often with your committee members; 2)
figure out a way to study during the long
drives; and 3) get SunPass for those turn-
pike drives!

Philip Kauth received a BS in Biology and
a minor in Chemistry from University of
Wisconsin-Stevens Point. After being
involved with the Native Orchid Conser-
vation Committee of the Northeastern

Wisconsin Orchid Society, he decided to
pursue graduate studies in orchid re-
search. He looked for universities whose
faculty studied orchid production and
found Dr. Wagner Vendrame (Homestead).
Philip's other co-chair is Dr. Michael Kane

Philip's research involves the produc-
tion of native Florida orchids, specifically
two terrestrial orchid species: Calopogon
tuberosus and Sacoila lanceolata var.
lanceolata. His goal is to develop pro-
tocols and techniques for mass-produc-
tion of terrestrial orchids using micro-
propagation and seed culture techniques,
because native terrestrial orchids are
excellent candidates for garden and
landscape plants. Literature on micro-
propagation of terrestrial orchids is
scarce, specifically for the native spe-
cies, and he hopes to increase the litera-
ture and our knowledge of the subject.
Another of his goals is to educate people
about native production, cultivation, and
As with other students, his major
challenge in working with faculty from
different sites is the distance; he has not
yet worked in Dr. Vendrame's lab. Philip
has found writing grants, exchanging
ideas, and keeping updated on current
projects is not easy. But he believes that
the positives outweigh the negatives.
Members of research centers around the
state have areas of expertise that faculty
in Gainesville may not have, such as
orchid production. Communication skills
are always improving, and the opportuni-
ty to collaborate with a dedicated indi-
vidual is exciting.

Carmen Valero-Aracama, a native of
Spain, is a doctoral student working with
Drs. Michael Kane (Gainesville) and Sandy
Wilson (IRREC). Carmen is the recipient
of both a Fulbright Scholarship and UF
Alumni Fellowship. Earlier she completed
her M.S. degree in Japan at Chiba
University under the direction of Dr.
Toyoki Kozai.

plete 2-3 internships during their academic career. This year 29 students from
the Gainesville and Milton campuses participated in internships throughout
Florida and the U.S.

2004 Student Trip

DestiXation: Holland by Dr.SandraWilson

May 2nd marked the beginning of the
2004 Environmental Horticulture Tour of
Holland. Four faculty members, one staff
member, three graduate students and 19
undergraduate students from Milton,
Gainesville, Fort Pierce, and Homestead
UF campuses visited seven major nurs-
ery/grower production sites, five famous
museums and/or gardens, and numerous
other flower markets, bulb fields, and
retail garden centers of Holland.
Highlights of the trip included
attending the PanAmerican Seed 2004
European Spring Pack Trials in Rijsenhout,
where more than 100 new varieties were
introduced, and the Hem Genetics Spring
Pack Trial in Hem where exciting new
series selections of Dianthus, Petunia,
Pelargonium and Salvia were displayed.
Our group also learned about the
breeding programs of several large Dutch
growers, including Fides Goldstock
Breeding in De Lier, who have become
important international suppliers of high
quality varieties of chrysanthemum,
kalanchoe, New Guinea impatiens,
fortunia and garden mum due to their
integration of new breeding techniques.
Micropropagation, potted orchid produc-
tion, and commercial seed cleaning and
sorting practices were also demonstrated
at various facilities.
Many of the nurseries utilize advanced
mechanization technology. Lekkerkerk
Plants in Groeneweg, who breed and
produce potted gerberas (and introduced
the Fortune Series F1 potted gerbera),
automated their facility in 2002 so that
young plants can be sorted by transplant-
ing into three sizes without human
intervention. Other complete automa-
tion techniques including media potting,
sorting cuttings and potted plants,
sticking cuttings, transplanting, moving
flats, and washing trays were seen at
Perfecta Plant in Kudelstaart (foliage and
rose producers) and Fides Goldstock
At Bloemenveiling Aalsmeer the daily
auction of over 19 million cut flowers in
12,000 varieties was witnessed firsthand.
Other destinations included the
Zuiderzee Museum in Enkhuizen, brilliant
displays of over six million bulbs at
Keukenhof Gardens in Lisse, the
Amsterdam floating flower market, the
Vincent van Gogh collection of 278 works
at the Kroller-Muller Museum, and the

17th-century-style formal gardens of Paleis
Het Loo.
This enjoyable international horticul-
tural tour afforded our group a great
opportunity to learn. As in previous
travels to a diverse array of international
destinations, no one left disappointed!

Observing advanced horticultural technology was a
major goal of this tour.

FDEP Grant Awarded to Verify Turfgrass BMP's

The Florida Department of Environ-
mental Protection (DEP) has awarded a
five-year, $3.5 million grant to verify Best
Management Practices (BMPs) for home
Lawn grasses. Home lawns are often tar-
geted as being primary contributors to
non-point source pollution of these water
bodies due to the nitrogen and phospho-
rus found in most home lawn fertilizers.
In reality, research has shown that proper
lawn fertilization practices will not cause
non-point source pollution. In an effort to
ensure that proper fertilization and man-
agement practices are followed by the
lawn care industry, BMPs have been de-
veloped for preservation of Florida's
water resources.
To provide additional data, a series of
experiments will look at how nitrogen
rates, sources, and application timing
impact non-point source pollution. Sever-

al lawn grass species will be used. The
research will look at nitrate and phos-
phate leaching in response to different
fertilizer and irrigation treatments
Research is being conducted in
Gainesville, Jay, and Ft. Lauderdale
under the direction of Laurie Trenholm,
Jerry Sartain, Bryan Unruh, and John
Cisar. Specific components of the re-
search include:

Nitrogen rates and irrigation amounts
on newly planted and established

Lawn grass phosphorus requirements

Impact of fertilizer application to dor-
mant and semi-dormant Lawn grasses

Nitrogen source and timing application

Guaranteeing Quality Flowers for Consumers

For consumers to plunk down
discretionary dollars for fresh flowers,
they want to know they're getting
value for their money. The prolifera-
tion of floral outlets has made avail-
ability a non-issue; the pivotal point
in consumers' minds now regarding
fresh flowers is value. In a consumer's
mind, stems that last and perform
well in the vase equate with value -
Stems that don't perform well prove
frustrating and, in many cases, cause
consumers to believe the failure is
somehow theirs. In either case, short-
lived flowers don't earn repeat cus-
tomers. The fresh flower industry
must conquer the many silent killers
of vase life-such as microorganisms,
ethylene, and water quality. Then cut
flowers will become, in essence,
"fresher," Lasting longer in the vase
and boosting consumer confidence in
the value that fresh flowers offer.
The floral post-harvest program
has been working to enhance flower
quality and extend flower longevity.
The value and importance of Cooling
(temperature management), Care
(harvesting and use of the proper
solutions) and Cleanliness have been
demonstrated in our program and
shared with growers, wholesale flo-
rists, retail florists and mass market
retailers nationwide. Recently, we
identified a combination of commer-
cial products that allows the supply

side of the industry to provide Lilies
and alstroemeria with leaves that
remain green and flower that last
several days longer. Flowers are
treated with a solution of natural
plant hormones and anti-ethylene
materials. We are encouraging the
floral industry to use these treat-
ments on ALL fresh cut Lilies and al-

ENH Summer Camp (continued from pg.1)

New Age Plants: Understanding the sci-
ence of genetics and the use of biotech-
nology in plant breeding and propagation.
Students were exposed to and practiced
tissue culture techniques. Campers also
learned about research being conducted
on-site to assist Florida's grape growers
combat a variety of plant diseases that
can be detrimental to the future of the
grape industry in Florida.

Plant Pathology: Through field explora-
tion and the use of microscopes, campers
learned what it was like to be a plant
pathologist, investigating evidence to
determine the possible cause of a plant's
demise and to identify the disease re-
sponsible for the damage so that correct
treatment could be applied. Campers
learned the differences between com-
pound and dissecting microscopes and the
proper use for each. They also had the
opportunity to get up close and personal
with plant diseases and fungus that are
common in the central Florida area.

Biological Control and Integrated Pest
Management: Appreciating the differ-
ences between good bugs and bad bugs,
and understanding just what makes a
pest a pest. Thanks to local faculty and
the UF Entomology department outreach
program many campers were helped to
overcome their fear of bugs by handling
live specimens in the department's trav-
eling insect show. Watching termites
trailing the ink lines they had just drawn
on paper fascinated campers. They also
Learned about diversity within the insect
world and the importance and function of
various insect parts. This session con-
cluded with the campers designing and
building their own insects out of fruits
and vegetables and various other materi-

Residential Landscape Design: Everyone
likes an appealing landscape and many
parents were excited to find out that
their children were exposed to the basics
of residential landscape design. The
importance of plant characteristics and
environment were emphasized to assist
campers in plant selection for a function-
al yet pleasing landscape design. Camp-
ers prepared both a before and after
design and were able to compare what
they thought design meant and what it
actually entailed. A brief walk through
the teaching garden brought to life many
of the concepts they had developed on

Arboriculture: Putting into practice
proper planting techniques and the value
of pruning; campers had the opportunity
to plant a tree in the teaching garden as
well as learn about tree roots and how
they grow. After observing a tree climb-
ing demonstration by graduate student
Scott Jones (Gainesville) they headed
back to the classroom and practiced
proper tree pruning techniques using
illustrations on the chalk board.

Hydroponics: Whether grown commer-
cially or for personal use, campers
learned that hydroponics is a viable alter-
native to traditional growing methods. A
video highlighted research being conduct-
ed in the Apopka area and how individu-
als could implement hydroponics garden-
ing in their own back yard. They learned
growing hydroponically outdoors requires
consideration of the seasons, importance
of plant selection and response to envi-
ronment. Proper fertilization was
stressed and campers were provided with
instructions, their own tub, seedlings,
and supplies to begin growing hydroponi-
cally at home.

Floral Design: Discovering the meaning
behind particular flowers and experi-
menting with Ikebana. Campers Learned
there are many hidden meanings behind
flowers and designed a virtual bouquet
that expressed a special message. After
a live demonstration of Oriental floral
design (Ikebana) students made their own
arrangement to take home.

In addition, their days included infor-
mational walks through our half-acre
teaching garden, outdoor games, crafts,
and other 'camp'-related activities. To
fill in the gaps, we invited speakers from
a local Raptor Rehabilitation clinic and
the Orange County Recycling program.
On Friday, one of our campers dads came
in and shared his collection of snakes and
did a presentation on snake handling. The
program was a weeklong event from 8 am
- 5pm daily. Initial feedback indicates
that our collective efforts were well
received. Many parents have requested
advanced registration for next year.

Dr. Jyotsna Sharma joined our facul-
ty at Quincy in January 2004 with a
60%/40% research/extension appoint-
ment. Her Ph.D. degree in Plant Sci-
ences is from the University of Missouri-
Columbia. Jyotsna subsequently com-
pleted a postdoctoral term with Dr. Bill
Graves at Iowa State University.
Dr. Sharma's research includes ecol-
ogy, physiology, molecular ecology and
propagation of rare native plants. A
major focus of her current program is
mitigation of contaminants in runoff
from agricultural sites. She recently
was awarded funding (in conjunction
with Dr. Tom Yeager and other co-prin-
cipal investigators from UF) from the
Florida Department of Agriculture and
Consumer Services Office of Agricultural
Water Policy to study remediation of
runoff water using native monocot
species at statewide nursery sites. One
major project in this grant is the evalu-
ation of contaminant removal capacity
of selected plants and associated mi-
crobes by assessing ecological interac-
tions among microbial communities in
both the rhizosphere and plant roots.
While she outlines and refines the
methodology for remediation projects,
Dr. Sharma is collaborating with re-
searchers at the center and at other
universities on several studies involving
native woody plants. Some of these
projects include assessment of nema-
tode susceptibility and propagation of
uncommon taxa using patented hor-
Dr. Sharma also is spearheading the
establishment of a botanic garden at
the North Florida Research and Educa-
tion Center. This is an ongoing project;
several plants already have been in-
stalled in and around the retention
pond as part of the first phase.

Dr. James L. "Jamie" Gibson is lo-
cated at the West Florida Research and
Education Center (WFREC) and holds a
60/40 Teaching/Research appointment.
Jamie received his B.S. degree in Plant
and Soil Science from West Virginia
University, Morgantown and later
earned his M.S. and Ph.D. degrees from
North Carolina State University, Ra-
leigh, NC in 2000 and 2003, respective-
ly. There, under the direction of Drs.
Brian E. Whipker and Paul V. Nelson, he
conducted research on various floricul-
ture crops. His Ph.D. research investi-
gated how fertilization affected shoot
and root growth of cuttings from vari-
ous vegetative annual stock plants.
Jamie also developed cultural require-
ments for ornamental kales, mustards,
and chards in the Floriculture Program
at NCSU.
Jamie will teach Introductory Nurs-
ery Management and Greenhouse and
Nursery Crop Culture. Web-based
courses currently being developed for
2005 and 2006 include: Advanced Nurs-
ery Management, Principles of Irrigation
and Water Quality in Horticulture (team
taught with Turfgrass Extension Special-
ist, Dr. Bryan Unruh), and Retail Man-
agement and Marketing in Horticulture.
Dr. Gibson will be working with the
WFREC Student Club to help coordinate
plant sales, nursery tours, and service
Jamie's research program will serve
to develop production and management
solutions for the ornamental plant
industry. Nutrient deficiency studies
with tropical perennials and retail and
marketing research at Northwest Flori-
da garden centers have become the
initial projects in Jamie's Nursery Pro-
duction and Management Research

Preparing Landscape
Plants for Winter

Cold damage from frost or a hard freeze
is a hazard to many outdoor plants in Flor-
ida. Even in south Florida, where tempera-
tures seldom reach the freezing mark, cold
injury can and often does occur. With prop-
er cultural practices and several protec-
tive steps, damage from Low temperatures
can be minimized.
Many plants go through a "hardening"
process with the onset of Low temperature.
Hardening is a natural protective device in
plants, enabling them to survive Low tem-
peratures. Light is important in this hard-
ening process. Plants receiving little or no
Light often do not develop hardiness, even
with decreasing temperatures.
Most tropical and subtropical plants do
not go through this hardening process, so
we must use artificial means to reduce cold
damage to them. Nutrition is very impor-
tant to increase a plant's cold resistance.
A plant that is supplied with all elements
essential for growth will survive lower tem-
peratures and recover faster. A plant suf-
fering from a lack or imbalance of nutri-
ents will be more susceptible to cold inju-
ry. Optimal nutrient levels should be main-
tained throughout the year, because most
plants grow during the winter but at a slow-
er rate. Fertilization should be reduced pro-
portionately, say to one-third the normal
rate, but should not be completely stopped.
This is also true for watering. Plants re-
quire water during the winter just as they
do during the rest of the year. Remember,
people don't stop eating and drinking in

the winter and neither do plants!
Another way to minimize cold injury is
by suitable windbreaks. Windbreaks reduce
wind speed and also conserve heat in an
area. Evergreen plants make excellent
windbreaks, and can be effectively placed
so an area stays warmer than it would if it
were in the open. You can thus protect some
of your tender plants by placing them in-
side a windbreak of evergreens.
Covering materials such as cloth, poly-
ethylene plastic and paper can also be used
to reduce cold injury. These temporary
coverings trap heat and maintain higher
temperatures near the plant. Other mate-
rials such as leaves or soil can be piled
around the base of plants to keep the stems
from freezing. Leaves may be injured or
even killed but these coverings may pre-
vent the entire stem and roots from being
Sprinkler systems have also been used
for cold protection. A constant flow of wa-
ter over the plant may be of value, howev-
er, if the supply of water is stopped or is
not supplied fast enough, ice can build up
and break the branches of the plant. This
method is usually not suitable for home-
owners, since large quantities of water are
needed and most irrigation systems are in-
To summarize, a good healthy plant is
the best insurance against cold damage. A
healthy plant means a proper fertilization
and watering program are used. Use wind-
breaks or protective coverings for the en-
tire plant or at least for the main stem when
a cold snap is anticipated. If all fails and
the plant freezes, replace it with a more
cold tolerant species or grow that favorite
ornamental as a pot plant which can be
moved indoors on those few cold days we
have in Florida.

Tropical plants such as crotons need artificial
means to protect them from cold damage.

Retirements In
Environmental Horticulture

After three years in the Environmental
Horticulture Department, Dr. Everett Emino,
who came to ENH in 2001 from a position as
IFAS Assistant Dean for Research, has retired to
Nova Scotia. Dr. Emino, who originally hails
from there, will devote his time to his family
and farmstead, which includes keeping up its
100-year-old-plus farmhouse. In ENH, he was
involved in floriculture research and was
greatly interested in keeping FLorida cut flower
growers economically viable in the face of
foreign competition. His 2003 sunflower trials
at UF were very popular with horticulturists
and cut flower growers. Dr. Emino got his M.S.
and Ph.D. degrees from the Michigan State
University. Come back to FLorida to warm up
anytime, Everett!

Mary Ann Andrews checking out a gift
at her recent retirement party.
Much to the sadness of faculty, staff and
students of Environmental Horticulture, Office
Manager Mary Ann Andrews has retired to
private Life. All of us have greatly benefited
from her expertise and kind helpfulness over a
span of nearly twenty years in our department.
Before coming to Environmental Horticul-
ture, Mary Ann worked in various positions at
UF, including Poultry Science, the Education
Department, as well as the IFAS Deans' Office.
Mary Ann was treated to a great outpouring of
affection at her recent retirement party from
all those who have had the pleasure of working
with her. Mary Ann's plans are many, and
include a bit of traveling, gardening, gourmet
cooking and baking, just a few of her many and
varied talents. We hope she'll find time in her
busy schedule to visit. Mary Ann...we already
miss you!
