CHRYSANTHEMUM MANUAL 
SOUTHERN CULTURE 
It is true the material presented in this manual is pri- 
marily from experience gathered for the northern part 
of the United States. Yet many of the pointers are 
similar for all parts of the country. 
We have noted that the early-flowering varieties 
from October 15 to November | flower approximately 
one week later in the southern states, while those 
flowering naturally November 15 to December | 
bloom one week earlier than the dates given in this 
manual. Last Pinch dates will have to be governed 
accordingly. 
When shading, it has been suggested that the black 
cloth be placed on the beds late in the evening, 7 or 8 
p.m. and left on until 8 or 9 a.m. Shading the usual 
time traps the excessive heat under the cloth and ap- 
pears to affect foliaae and flower buds. Pink and 
Cloth Houses 
Much has been written about the construction and care 
of the cloth house. It seems that this subject is well 
taken care of, although there are a few new ideas 
that should be mentioned.

During the months of July and August, little growth 
may be expected, therefore fertilization should be kept 
to a minimum. When the nights get cooler in Septem- 
ber, October and November, growth is more rapid, 
and the fertilization program should be parang 
accordingly. 
The young plants should be illuminated until May | 
to prevent premature flower buds. 
The length of day is constantly changing. In Ohio 
the shortest day has 9 hours of light, while the longest 
day length is 15 hours. In Florida, it varies from 10 for 
the shortest and 14 for the longest. In Ohio, the day 
length will change about 15 minutes each week. 
To grow quality stock, it is necessary to use some 
type of covering such as aster cloth, onion bag or 
Saran. Saran plastic shade cloth woven from flat, 
elliptical yarn is now available to give varying per- 
centages of shade, Cloth can be obtained that will 
cast 46% to 90% of shade. The cloth that casts 46% 
shade is recommended for chrysanthemum culture. 
Saran will outlive copper screening.
