The Use of Floral Arrangements
in Alabama Funeral Homes
Alan Cotton and Kenneth C. Sanderson
Nature of Work:
A survey of 100 Alabama funeral homes was conducted to determine:
(1) If the funeral home personnel believed that flowers help comfort the
family, (2) to what extent funeral home directors suggest a particular
florist to the family, (3) if any restrictions are placed on floral offerings
accepted at the funeral home and what these restrictions are, (4) 
what type
of floral arrangements are preferred in the funeral home, (5) in the 
opinion
of the funeral home personnel, what type of flowers hold up best, (6) what
complaints funeral homes have against flowers, (7) what trend the 
directors
see in the omission of flowers and if the omission of flowers hurts their
business and (8) if the funeral homes believe they have a good working
relationship with the florists of their city. Seventy-five 
funeral homes
replied to the questionnaire.
Results and Discussion:
(1) All of the funeral home directors believe that flowers do help 
com-
fort the family.
(2) Only 12 percent of the funeral home directors said they recommend a
particular florist; 88 percent 
do not.
(3) Ninety percent of the funeral home directors do not place 
restrictions
on types of floral offerings accepted. Ten percent of 
the directors place
restrictions on size, quality of flowers, appropriateness and construction 
of
the arrangements.
(4) The funeral home directors favored floral designs as follows: Sprays
(72 percent), specialty pieces (17 percent), baskets (6 percent), 
potted plants
(4 percent) and vase arrangements (1 percent).
(5) Almost 75 percent of the directors stated that carnations 
remain fresh
for the longest period of time in their funeral homes; chrysanthemums 
(13 percent),
gladiolus (8 percent) and roses (2 percent) are listed 
next as long-lasting
flowers.
(6) Arrangements or designs leaking water is the major complaint 
of the
funeral home directors against florists. Failure to deliver 
on time, poor quality
of flowers, poor design in arrangements, lack of variety in flowers, and steel
picks cutting employees hands are ranked next, in order. One funeral home director
thinks flowers are a waste of money and that too many flowers are carried to
the funeral home.
(7) Twenty-nine percent of funeral home directors replied that the trend of
omitting flowers at funerals is increasing; 60 percent of the funeral home
directors said the trend is constant and 11 percent stated that the omission
of flowers is decreasing. Most Alabama funeral home directors (72 percent) believe
the omission of flowers does not hurt their business.
(8) Almost all of the funeral home directors (96 percent) reported
they have a good working relationship with the florists of their city;
only 4 percent stated they do not.

Effect of Growth Retardant Treatments on the Height of
Rieger Elatior Begonias cv. Schwabenland Red
Kenneth C. Sanderson and Willis C. Martin, Jr.
Nature of Work:
Schwabenland Red Reiger begonias were obtained from a commercial source
and potted into 6-inch clay pots containing a soil, sphagnum peat moss, per-
lite (1:6:3, v/v/v) medium on March 15. This medium was amended prior to
transplanting with 56.7 g of Osmocote 14-14-14 fertilizer per bushel. Every
2 weeks, the plants were fertilized with 20-20-20 fertilizer at the rate of
227 g per 100 gal. All plants were drenched with a fungicide mixture of 21
ml of Truban 25 Ec and 60 g Benelate WP per 39 gallons immediately after
transplanting. Sprays of Kocide 101 (2 lb. per 100 gallons) were alternated
weekly with sprays of Daconil 2787 (2 lb. per 100 gal.) to control foliar
diseases. For the first 2 weeks of growth, the plants were lighted with 10
ft-c of incandescent light for 1 hour each night. Plants were grown under shaded
conditions (2,000 ft-c) at 700 F. Watering was done with a Chapin automatic
watering system to prevent disease problems. The growth retardant treatments
shown in Table 1 were applied to 10 plants per treatment on April 16. Drenches,
consisting of 150 ml of material, were applied directly to the medium surface.
A Halaby mist blower was used to apply the sprays. Data on height were obtained
on May 13.
Results and Conclusions:
All growth retardant treatments reduced plant height, however, a drench
of 2 p.p.m. ancymidol caused the greatest height reduction. All ancymidol
treatments were more effective than chlormequat drenches, the currently
suggested height control treatment for Rieger begonias. Flowering of plants
treated with ethephon was delayed and perhaps even reduced.

Effect of Various Experimental Chemical Pinching Agents on the
Height of Flowering of Potted Chrysanthemums
Kenneth C. Sanderson and Willis C. Martin, Jr.
Nature of Work:
Two experiments were conducted to determine the effects of 3 new experi-
mental, chemical pinching agents on potted chrydanthemums. Exp. 1 considered
2 Armak chemicals, TD 6773 MO and TD 6528. Exp. 2 considered Uniroyal's
UBl-P273 in addition to the Armak compounds. Sunny Mandalay chrysanthemums
were grown under normal cultural conditions for potted chrysanthemums. In Exp.
1i, five unrooted cuttings were directly rooted under mist into a 6-inch pot on
February 14. Photocontrol for Exp. 1 plants consisted of lighting them at
night for 4 hours from February 14 to March 5, and covering them with black
cloth from 4:30p.m.to 7:30 each day from March 5 until the flowers showed color.
Plants for Exp. 2 were propagated on February 28, lighted February 28 to March
18 and blackclothed from March 18 until show of flower color. A 1:1:1 medium
of soil, sphagnum peat moss, and perlite was amended with 75 g limestone, 
50 g
superphosphate and 50 g of gypsum prior to use as the cultural medium. Plants
were fertilized weekly with 20-20-20 at the rate of 2 lb. per 100 gal.
Pinching treatments were applied when the shoots were judged appropriate
for pinching (approximately 2 weeks after sticking the cuttings). A Halaby mist
blower was used to apply a minimum amount of chemical material or until the
leaves glistened. No surfactant was added to any of the treatments (some chemicals
contained one). Each experiment was replicated twice. Data on height and the
number of flowers per plant were recorded at flowering.
Results and Conclusions"
Successful pinching of potted chrysanthemums was obtained with sprays
of 1.50% TD 6773M0 in Exps. 1 and 2 and 0.50% UNl-P293 in Exp. 2 (Table 1).
Further testing of these chemicals is warranted. All chemical treatments reduced
plant height in Exp. 1. With the exception of TD 6773M0, all the Armak chemi-
cals increased plant height in Exp. 2. Uniroyal's UB1-P293 caused a slight
reduction in plant height in Exp. 2. Armak's TD 6528 at concentrations of
0.0-. to 0.4CVP drastically reduced the number of flowers per plant and appeared
to be phytotoxic on plants at these concentrations (plants showed distortion
and burn on the margin of leaves).

An Evaluation of ACR 1158D as a Growth Retardant on Chrysan-
themums, cvs. Sunny Mandalay and Orange Bowl
Kenneth C. Sanderson and Willis C. Martin, Jr.
Nature of Work:
Three experiments were conducted from April 29, 1975 to August 18, 1975
in evaluating a new growth retardant,ACR 1158D,manufactured by Hoffman-LaRoche.
Exps. 1 and 2 utilized the chrysanthemum cultivar Sunny Mandalay whereas Orange
Bowl was the test cultivar in Exp. 3 Six-inch pots of 5 plants each were
treated 2 weeks after pinching (when the breaks were 3-4 cm long) with the follow-
ing treatments: none, 5,000 ppm SADH, 50 ppm ACR 1158D, 100 ppm ACR 1158D and 150
ppm ACR 1158D. Plants were sprayed with a fine mist until incipient runoff.
Treatments of 30 pots each were replicated 4 times. Normal greenhouse culture
for potted chrysanthemum was used: liquid fertilization, photocontrol for
flowering and a 620 F. minimum night growing temperature. At flowering
the height and number of flowers per plant were recorded.
Results and Discussion:
All growth retardants reduced height, however a 5,000 ppm SADH spray
yielded the shortest plant (Table 1). Sprays of 150 ppm ACR 1158D were more
effective in reducing plant height than lower concentrations. Higher con-
centrations of ACR 1158D should be investigated but in Exps. 2 and 3, plants
sprayed with 150 ppm ACR 1158D visually did not appear to be taller than plants
sprayed with 5,000 ppm SADH. In general, growth retardant treatment increased
the number of flowers per plant (Table 1). In all experiments, plants sprayed
with 150 ppm ACR 1158D had more flowers per plant than untreated plants.

Effect of Ancymidol (A-Rest) on Growth and Flowering
of Seed Propagated Geraniums
Kenneth C. Sanderson and Willis C. Martin, Jr.
Nature of Work:
Ancymidol is reported to retard plant height and stimulate flowering in seed-
ling geraniums. In 2 experiments the material was applied to seedlings at the
2-4 true leaf stage using the following concentrations: 0, 0.41 mg per sq. ft.
0.63 mg per sq. ft., 0.85 mg per sq. ft., and 1.10 mg per sq. ft. A spray
volume of 0.9 ml per plant was used in applying the sprays.
Exp. 1 was conducted from April 26 to July 10, 1974. Seedlings of Care-
free Scarlet, Carefree Bright Pink, Carefree White and Sprinter were pro-
pagated in peat pellets (Jiffy-7's) on April 26, transplanted to a 1:1:1
(v/v/v) soil, sphagnum peat moss and perlite 
medium on May 28 and treated on
June 10. The seedlings were potted in a Ranco fiber pot which may have in-
fluenced the result. The experiment was repeated in the spring of 1975 using
Carefree Scarlet seedlings propagated in Jiffy Mix. Three types of pots were
used: clay, fiber,and plastic.
Results and Conclusions:
The retardant action of ancymidol has been reported to be interferred
with by pine bark media. Results of the 1974 experiment showed very little
difference in plant height. Ancymidol plants flowered earlier with little
differences were observed in plant height in the 1975 experiment. Despite the
fact that the 1974 experiment utilized a wood product pot, it does not seem
to be the cause of retardant failure. Plants in both experiments were sprayed
during hot weather and high temperature has been reported to inactivate another
retardant (SADH). Other causes of inactivation which should be investigated
are type of sprayer, spray coverage, timing of spray, time on plant, humidity,
and plant age.

Effect of Watering Methods on Growth of Potted Chrysan-
themum cvs. Nob Hill and Yellow Nob Hill
Kenneth C. Sanderson and Willis C. Martin, Jr.
Nature of Work:
Watering methods have been reported to influence the growth of potted
chrysanthemums. An experiment conducted in 1975 considered hand watering,
Chapin EV-2"spaghetti" watering, and Vattex mat (capillary) watering. Rooted
cuttings of the chrysanthemum cultivars Nob Hill and Yellow Nob Hill were
transplanted to clay pots containing a 1:1:1 soil, sphagnum peat moss and per-
lite medium on February 19, 1975. Normal cultural practices for the flower-
ing of single stem potted chrysanthemums were followed. All plants were sprayed
with 5,000 ppm SADH (B-Nine) on March 12 and March 26. Data on plant dry
weight were collected at flowering on May 7.
Results and Conclusions:
The plants did not appear to differ in plant height. The 2 applications
of SADH probably were responsible for height control. Dry weights of plants
were as follows:
Nob Hill Yellow Nob Hill Mean
Hand Watering. ..... . . . 4.9 4.5 4.7
Vattex Mat .. ......... .5.4 6.3 5.9
Chapin Tube .. ........ 5.2 5.1 5.2
The automatic watering systems produced plants with increased dry weight
Capillary watering by a Vattex 
Mat yielded plants with 
the most dry weight.

An Evaluation of Four New Chemical 
Pinching
Agents on Azaleas
Kenneth C. Sanderson and Willis C. Martin, 
Jr.
Nature of Work:
Azaleas are usually pinched 
or sheared to induce branching. 
Recently,
a chemical pinching agent, Off-shoot-0 
has been introduced that effectively
pinches the azalea by killing 
the top of the plant. Occassionally, 
plant
damage will occur with Off-shoot-0 
if plants are overtreated or 
in a
succulent condition. Cultivar 
response to Off-shoot-0 also varies. 
Several
new materials have been tested 
as pinching agents on various plants.

The present investigation considers 
4 new experi-
mental chemicals, Hoffman-LaRoche's 
Atrinal
TM 
and Armak's TD 6528, TD 6772M0
and TD 6596 were investigated in 
Exp. 1 and Atrinal
T 
was compared with shear-
ing and Off-shoot-0 in Exp. 2.
In Exp. 1i, established liners 
of Kingfisher azaleas were 
treated on
January 14 as shown in Table 1. 
Plants were sprayed until run-off 
with a
Halaby mist blower. No surfactant 
was used in formulating sprays. 
Sheared
plants were sheared according 
to commercial practices. 
The number of shoots
per plant was determined on 3 plants 
per treatment and 4 replications 
on April
15, 1975.
For Exp. 2, liners of the azalea 
cultivars Alaska, Gloria, Red 
Gish, Red
Ruffles were potted on March 
31, sheared on July 3 and treated 
on July 10.
A low pressure, high volume 
hand sprayer (ASL Killaspray) 
was used to apply
4 concentrations 
of AtrinalTM and 
Off-shoot-0R at 
the concentration 
shown in
Table 2. Approximately 110 ml 
of spray were used to treat 60 plants 
in a 65.2
sq. ft. area. Sprayed to 
visible leaf coverage, an 
estimated 18.3 ml of
material was applied to each 
plant. Shoot number per plant 
was determined
during October 3 through October 10.
Results and Conclusions:
None of the chemical treatments 
produced as many shoots as 
shearing in
Exp. 1 (Table 1). All chemical treatments 
yielded plants with more shoots
than untreated 
plants. AtrinalTM 
at 4,000 ppm 
produced plants 
with the most
shoots in Exp. 2. All Atrinal-treated 
plants had more shoots than 
plants
sprayed with Off-shoot-0R. 
Generally, all cultivars gave 
a similar response
to treatment. Red Gish and 
Alaska plants produced comparable 
shoot numbers
at 3,000 ppm AtrinalTM 
as at 6,000 ppm AtrinalT

Effect of Growth Retardants on Clerodendron
thomasoniae Balf.
Kenneth C. Sanderson and 
Willis C. Martin, Jr.
Nature of Work:
Clerodendron thomasoiae 
Balf. is a tropical, 
twining, evergreen shrub
frequently found 
in conservatories 
and greenhouses 
throughout the South.
Its genus name is 
derived from the 
Greek kleros meaning 
chance and dendron
meaning tree. Natives 
believed that the tree was 
chance cure for certain
ailments. C. thomasoniae 
is one of 100 or more 
species in the Verbenaceae
family. Common names for the 
plant include glorybower, white 
bleedingheart,
bleedingheart glorybower, 
bleedingheart, bagflower, Cornell 
flower, glory-
vine, baf-flower, Southern 
bleedingheart.
For many years C. thomasoniae 
has been grown as a pot plant 
in Europe.
In Norway approximately 
75,000 plants are grown for 
Mother's day sales. 
It
can also be grown in 
hanging baskets, on trellises 
and arbors, or as a trained
specimen plant in tubs. 
Major production problems 
are control of height
and flowering. Pinching 
has been recommended in the past 
to compact growth,
induce branching, and stimulate 
flowering. Chlormequat and 
a-cylopropyl-a-
cylopropyl-a-methoxypropyl-5-pyrimidine 
methanol (ancymidol) 
have been re-
ported to show promise 
as growth retardans on 
C. thomasoniae however 
confusion
exists on chemical effectiveness, methods of application 
and rate of appli-
cation. Auburn research 
compared these two retardants 
on plants propagated
from one node cuttings 
(2 cuttings per 12.5 cm 
pot) on July 1, 1974. 
Plants
were grown in steam pasteurized, 
1:1:1 soil, sphagnum peat moss, 
and perlite
medium which was amended prior 
to planting with 0.6 kg 
CaNO
3
,1.1 kg 20 super-
phosphate, 0.2 kg FTE, 
.03 kg FeS0
4
, and 1.6 kg OsmocoteTM1 
"14-14-14" (14.0
N-6.2p-11.6) per m3. 
Following transplanting, 
plants were fertilized 
each week
with liquid fertilizer 
(20.0N-8.8P-16.8K) at the 
rate of 2.4 g per liter. 
Plants
were grown in a lightly 
shaded greenhouse equipped 
with fan and pad cooling.
Plants were soft pinched 
on July 29 and August 2. 
Ancymidol and chloromequat
treatments were applied 
to the plants on August 
26. Method of application
and rates were determined 
from preliminary tests and 
previous research (12).
Drenches were applied directly 
to the medium and sprays 
were applied to the
plants with a Halaby mistblower 
until the leaves glistened 
(Table 1). A
randomized block design 
consisting of 3 replications, 
6 treatments, 4 pots per
treatment and 2 plants 
per pot was used. Plant 
height was recorded 
on the
plants on September 30.
Results and Discussion:
Ancymidol drenches (0.3 or 0.6 mg per 
13.5 cm pot or sprays (1.9 to 3.8
mg per plant were more 
effective in reducing 
plant height and overcoming 
the
vining habit than 450 mg 
chloromequat drenches (Table 
1). The combination 
of
450 mg of chlormequat with 
0.3 mg of ancymidol did 
not increase the effect-
iveness of a drench in 
retarding Clerodendron 
height.
