The Bulletin of the Environmental Horticulture
Department at the University of Florida

Message from Our Chairman
Terril A. Nell


We are entering a new era with our academic pro-
grams -a new interdisciplinary major, Landscape and
Nursery Horticulture -that combines knowledge of
science and horticulture with the strengths of
Agribusiness Management, Communications, and
Landscape Architecture and Public Gardens. Our ar-
ticle on page 4 gives an in-depth look at our new
academic programs.
Much more is happening in the arena of statewide
Environmental Horticulture. Our faculty are striving
to make new information readily available to the
public on our website at hort.ifas.ufl.edu, and
through the Extension digital information source
(EDIS) at edis.ifas.ufl.edu. These websites can pro-
vide a wide array of information about all aspects of
Environmental Horticulture.
Finally, new research topics are expanding the im-
portance of environmental horticulture in the state
and are gaining recognition nationally and interna-
tionally. These programs deal with: the study of the
potential invasiveness of new ornamental plants; es-
tablishment and growth of trees in the urban envi-
ronment; reestablishment of native landscapes in
coastal areas, genetic engineering to extend flower
life; and studies leading to efficient use of water
and nutrients in production and landscapes. Clearly,
the use of plants and turfgrass affects the lives of
every person in Florida each day. We seek to main-
tain the Environmental Horticulture and Turfgrass
Industries as the "Environmental Stewards" of pub-
lic landscapes through our research programs.
Our successes are due in large part to our alumni
and friends, the university administration, and the
industry partnerships we have established within the
state, nationally and internationally. Thank you for
helping us develop new knowledge to share with our
students, the industry and the public.

Public Gardens Tour of Italy
May 7th through 17th, 2001
Ten days in Italy visiting some of the oldest gardens in Europe may have
seemed like a holiday to some. On the contrary! To the thirty one students
and faculty who took part in UF Environmental Horticulture's Public Gardens
Tour of Italy, it was a superlative learning experience. Though billed as a
public gardens tour, it also featured urban landscapes and production nurser-
ies as well as Italian culture, history, religious and secular architecture, and
cuisine. The trip complemented the studies of those whose major specializa-
tion in horticulture was either Public Gardens Management or Landscape and
Nursery Management.
An all-night flight brought the group into Rome. The Vatican and Sistine
Chapel tour was first on the following afternoon. The gardens at Villa d'Este
and Villa Lante were the first horticultural attractions with their hilly terrain
and mature plant collections. Striking differences in plant materials and
climate were immediately apparent. The cool May Mediterranean climate
caused significant
differences in flowering
season from torrid
Florida, allowing the
group to witness azaleas,
roses and geraniums in
full bloom. These first
gardens were excellent
introductions to the
recurring elements of
Italian garden design.
The tour had a wide
geographic range,
extending northward
from Rome through
Tuscany, along the Riviera, Villa d'Este, a landmark garden in Tivoli outside Rome
across the Alps into the Piedmont, and into the Lake Como District. Students
viewed plant materials unseen in Florida, the grandeur of ancient specimens,
and quickly gained a sense of the influence of climate on flora. The merging
of history, culture, religion, art and horticulture apparent in Italian garden
design was also impressive.
Beginning in Villa Lante, and over the following three days in Florence,
students were intrigued by formal hedges, topiary, and numerous examples of
pleaching and pollarding on public street trees. During the time in and around
Florence, a gem of medieval art and architecture, the group toured one of

2001 International Master

Gardener Conference Hosted

by the University of Florida
by Tom Wichman, Florida Master Gardener Coordinator

In late May, the University of Florida
hosted the 2001 International Master
Gardener Conference and Trade Show
in Orlando. The conference was lo-
cated at the Hilton in the Walt Disney
World Resort.
The event opened to welcoming re-
marks from Dr. Terril Nell, our Depart-
ment Chair; Dr. Mike Martin the Vice
President of IFAS; and Greg Ruse, the
Vice President of Disney Construction
Manufacturing and Horticulture.
The four-day event was highlighted
by three general sessions. Rebecca
Kolls of Rebecca's Garden, who often
appears on Good Morning America, dis-
cussed her experiences as the host of
a gardening show. Ruth Kobayashi of
Paul Ecke Ranch, and Dr. Dave Clark
of our Department, discussed the his-
tory and future of plant breeding in-
cluding genetically modified plants.
The presentation by Rene Van Rems of
the California Cut Flower Commission
gave a history of flowers. Rene's per-
formance was in character as a sev-
enteenth century Flemish artist and
was sponsored by a host of companies
from the floral industry.
The conference involved as many as
twelve concurrent hands-on workshops
and educational lectures covering a
wide range of horticultural topics.
There were nationally known speak-
ers significant representation from the
UF Environmental Horticulture Depart-
ment. A poster display of selected
Master Gardener projects from around
the country, and educational presen-
tations by the volunteers, gave a per-




spective of the excellent work going
on across the U.S.
The horticultural trade show was
marked by large crowds, generous ven-
dors, and numerous door prize draw-
ings. Master Gardeners from Florida
were recognized for their outstanding
projects and many for ten, fifteen, or
twenty years of service to the Univer-
The final day of the conference took
place at Epcot. The 2001 International
Flower & Garden Festival was in full
swing and the Master Gardeners were
treated to a private viewing of the
Gardens of the World Showcase with
the opportunity to meet the garden-
ers who make the magic. A dessert
reception was sponsored by the Epcot
International Flower & Garden Festi-
This event was supported by at least
30 generous sponsors, who donated
over $150,000. The conference was
attended by 749 Master Gardener Vol-
unteers from 32 states and three coun-
tries. It was an incredible opportu-
nity to showcase the University of
Florida, IFAS, the statewide Environ-
mental Horticulture Program and the
Florida Master Gardener Program.
International Master Gardener Con-
ferences occur every two years. There
is a rotation designed to take the event
to different regions of the U.S. and
Canada. The 2003 conference is
scheduled for June 19 22 and will be
held at the Northern Kentucky Conven-
tion Center in Covington, Kentucky.

New 21st Century

The Environmental Horticulture
Department at the University of Florida
announced major changes to its Land-
scape and Nursery Management program.
In an effort to better connect with the
demands of the growing environmental
horticulture industry and academic
discipline, faculty has recently developed
a new undergraduate interdisciplinary
Drawing upon expertise in landscape
architecture, agricultural business,
agricultural communications and horticul-
tural sciences, the new program offers
three specializations for students:
landscape and nursery management,
public gardens management, and environ-
mental horticulture operations. Addi-
tional supporting course work in technical
agriculture is provided by soil and water
science, entomology and nematology,
forestry and plant sciences.
A minor in Agricultural Business will
be awarded to all students in the land-
scape t nursery management specializa-
tion. They will be exposed to courses in
business and human resource manage-
ment, finance, strategic selling, and
"This new curriculum will prepare our
students to meet the challenges of
business today. That means a well-
rounded individual who understands all
aspects of the horticulture industry.
Graduates will be capable of working with
people, while understanding the concepts
of good design, maintenance and success-
ful growing practices," states Dr. Terril
Nell, department chair.
Understanding the importance of
work experience, students are required to
complete an internship for a minimum of
two months at a landscape management
firm, nursery or plant production facility.
With the program offered in five
locations throughout the state, the
Department of Environmental Horticulture
is actively seeking new students to fill this
current demand for knowledgeable,
experienced individuals.

Jenny Hayes completed her summer
internship with Congressman Adam
Putnam in Washington, D.C. Jenny is a
member of Florida Blue Key, has been
elected to the Golden Key National Honor
Society, and has received numerous
scholarships and awards since entering
Environmental Horticulture's undergradu-
ate program. After graduation, she plans
to study business and agriculture law. Congressman Adam Putnam
Congressman Putnam said of Hayes, and Jenny Hayes
"Jenny really jumped into her responsi-
bilities here. I was an intern for Congressman Charles Canady so I've seen what an
internship is like from the other side," reported Putnam. "Not only is Jenny sharp,
but her knowledge and appreciation of the challenges facing Florida's Agriculture
industry allowed her to contribute to the development of the Farm Bill in a way few
summer interns could."

Back to School, Back to Life
by Kimberly K. Moore, Asst. Prof., Ft. Laud. REC
There are many
unique students
enrolled in our
statewide pro-
gram. I had the
pleasure to work
with one of them
this summer in my
sl laboratory.
Jeanette Wooding
received one of
SUF's College of
Agricultural and
Life Sciences
research intern-
ships. She be-
came a part of the Environmental Horticulture Department
in an interesting way.
Jeanette, originally from Jamaica, has lived in South
Florida since 1978. She was a legal secretary for 14 years,
put her two children through medical school, and enjoyed
gardening and floral arranging in her free time. After her
children finished medical school, she decided to return to
school herself.
Jeanette was working toward an AA degree in health
service administration when her husband passed away. She
sought comfort in her garden, and one day, while working
there with her son, she confided her uncertainty about what
to do after graduation. He suggested a career in something
she loved gardening. With this thought, Jeanette visited
the Fort Lauderdale REC and decided to pursue an Environ-
mental Horticulture degree. After putting two children
through medical school, her children are now paying for
their mother to get her own degree.
Looking around at Jeanette's garden, it is obvious that
she loves what she does. Jeanette said she "found" herself
in her garden, which brings her joy
during difficult times. When
she graduates, Jeanette
wants to teach others about
the pleasures gardening
can bring them. She is I.

If anyone is wondering what to do
with millions of recalled Firestone
tires, a University of Florida re-
searcher has a suggestion: Grind
them up and spread them on athletic
fields and golf courses. UF turfgrass
specialist Grady Miller said ground-
up tires, also known as crumb
rubber, could help increase the
durability of turf used in high-traffic
applications. "We want to prevent
the kind of damage people can cause
to turfgrass," said Miller, an assis-
tant professor Environmental
Horticulture. "Turf can be stripped
out by cleats in the goal and corner-
kick areas of soccer fields and
between the hash marks on football
fields. "For golf courses, it's
primarily where carts enter and exit
near greens and tees," he said.
Miller is testing the rubber product
on test plots of grass on the UF
campus, on a Gainesville-area golf
course and several area athletic
fields. In one method, the crumb
rubber and two other compounds
being evaluated are spread evenly
over the top of grass, a process
known as top-dressing. In another
process called aerification, research-
ers literally punch small holes in the
ground and fill them with test
material. Eventually, the products
work their way down into the soil
layers, where they may deliver the
strongest protective benefit, he
Miller said after more than a year
of study, the crumb rubber does
seem to protect grass to some
degree. While more research is
needed to assess the amount of that
protection, the use of the crumb
rubber could provide another

Grady Miller, a turfgrass specialist with
the Environmental Horticulture Depart-
ment at Gainesville, spreads crumb rub-
ber on a test plot of grass on the UF cam-
pus. Miller says crumb rubber, made from
ground-up automobile tires, could help
protect grass used in high-traffic areas
such as golf courses and athletic fields.
He said the process also is a safe way to
recycle old tires and keep them out of
landfills. (AP photo by Eric Zamora, UF/

benefit, he said. "The fact that we
can recycle a waste product like old
tires and improve turf condition at
the same time is a great thing,"
Miller said. "When tires are pro-
cessed into crumb rubber, the steel
belts and all potentially hazardous
metals are removed. This leaves an
essentially inert compound that will
stay in the soil and protect the turf
for several years," he said. "We may
actually have a different use for
rubber that can potentially improve
how we manage turf." According to
Miller, managers and athletes alike
would benefit if grass in athletic

fields could be made healthier. "Turf
managers would benefit because it
might be easier to manage grass
which may require less fertilizer or
water," Miller said. "End users would
benefit as well in that they may be
able to play on better-quality turf."
During the course of the study,
Miller said, researchers noticed an
unexpected outcome from using the
product. "The black rubber absorbs
a lot of heat," Miller said, "and last
year we noticed a strong greening
effect with this particular treatment.
This may have been caused by heat
transfer from the rubber to the grass
early in the spring during the period
when grasses are just starting to
actively grow." In addition to the
crumb-rubber product, researchers
are evaluating ordinary sand and a
heat-treated clay compound Miller
said could prove particularly useful
in water-starved areas. "The porous
ceramic compound holds water, so
there's been a lot of interest from
environmental groups and turf
managers," Miller said. "The goal is
to find ways to reduce water use by
holding more moisture in the soil."
Miller said the bottom line is to
determine if any of the materials
actually help the grass. "We are still
trying to work out the differences
between the three treatments and
see if one of them has any specific
advantage," Miller said. "One may
protect against physical damage
better, while another may have
better water retention or just may
improve grass density. "When you
cover grass with sand, it often
promotes denser growth," he said.
"This may be a benefit of the sand
that we don't see with these other
coarser materials."

Gardening Tips


by Dr. Robert J. Black
As the temperature begins to moderate,
the desire to work in the yard returns to
most Floridians. For most of us, it's j ust been
too hot to do anything but try to keep the
lawn from becoming a hay field. As a re-
sult, many hours of
hard work will be re-
quired to restore our
landscapes to what
they looked like in the
spring. This is not all
bad since most of us
enjoy working out-
doors and we all can
use the exercise.
A job of this magni-
tude can be over-
whelming unless you
approach it in steps.
The logical first step is
a general clean-up of
the home grounds. Re-
move those summer
annuals which are be-
ginning to look shabby.
Weed and remove tree
branches and other
trash from flower and
shrub beds. Edge side-
walks, driveways and
beds if you have ne-
glected this task dur-
ing the summer It
After the clean-up is accomplished, you
are ready to move to more enjoyable tasks.
If you want a fall flower garden, start pre-
paring a good planting bed. Locate the bed
in an area which receives full sun at least
half a day and stay away from large trees.
Tree roots are strong competitors for fertil-
izer and water so plant your flowers in a
spot where trees will not compete. Spade
or till the planting site six inches deep sev-
eral weeks before planting. Incorporate two
to three inches of organic matter and a com-
plete fertilizer such as 6-6-6 at the rate of
two pounds per 100 square feet of bed area.

Hardy annuals you can plant in late Sep-
tember include alyssum, calendula, can-
dytuft, dianthus, baby's-breath, nasturtium,
pansy, petunia, phlox, snapdragons, statice,
sweet peas, and viola. These are just a few
of the plants which can be started now.
Don't forget that September is the month
to apply a fall application of fertilizer to
St. Augustine and bahiagrass lawns. Centi-
pede lawns should have been fertilized last
month. A complete fertilizer such a 16-4-8
should be applied at the rate of one pound
of actual nitrogen per 1000 square feet of
lawn. Shrubs and trees which do not receive
fertilizer when the lawn is fertilized should
receive an application at this time.
September and October are the months
when gibberellic acid is used on camellias.
On many varieties, the flower size may be
increased significantly, producing a bloom
much earlier than would be the case with-
out treatment.
Select a well developed flower bud. Re-
move the pointed growth bud adjacent to
the flower bud. A
small cup will be left
where the growth bud
has been removed. Fill
the cup with one drop
of the acid solution.
Usually a difference in
bud size between
treated and untreated
camellia buds is ap-
parent in a week. By
encouraging earlier
flowering in camellias,
freeze damage is re-
duced and flowers be-
come available for
holiday decorations.
Watch your lawn
and ornamental plants
for pests. It's still
warm enough for in-
sects like scales, white
flies, mites, aphids,
and caterpillars to be
damaging shrubs. Sod
webworms and army-
worms can ravage
lawns and brown
patch disease can be a problem. Watch out
for these problems and start control mea-
sures as soon as you notice damage.
This should keep you busy until it's time
to start raking leaves. Remember to take
your time and don't try to do everything in
one day. Fall gardening can be a very relax-
ing and enjoyable experience.

Everett R. Emino (continued from pg.6)

he will develop a research program
focusing on cultural systems for green-
house and outdoor production of cut
flowers, cultural physiology of greenhouse
crops and the horticultural and agronomic
utilization of compost for sustainable
agricultural systems. He will join faculty
from our teaching programs around the
state in developing the plant propagation
course for interactive distance education.
He will be responsible for teaching the
plant propagation laboratory in
Gainesville and other courses that will
enhance the Landscape and Nursery
Management Specialization. Everett is
also looking forward to mentoring gradu-
ate students and having graduate students
join his research program. As part of the
transition, Dr. Emino will be spending next
summer on a six month faculty develop-
ment leave.
Dr. Emino has two grown children and
two grandchildren. He and Jeanette
MacBean of Truro, Nova Scotia were
recently married and returned to Gaines-
ville after a honeymoon in Cape Breton
Island, Nova Scotia. In addition to his new
responsibilities in the department he is
looking forward to spending time with his
wife and grandchildren and using his
vacation time at his farm.
