LETTUCE 
Sow 14 to 1 pound in seedbed to plant an acre, or plant 1 to 142 pounds per acre in field. 
For the garden make two plantings at different times. Sow 1 packet in a protected seedbed for 60 to 80 plants to set 50 to 75 
feet of row at each planting for a family of 3 or 4 people, or plant 1 packet of seed in 50 to 75 feet of row at each planting. 
Culture. First sowings are made in Florida the beginning of 
September and continue until March. Low, damp soil is best 
suited for this crop. Lettuce must be grown rapidly in order 
to give it size, tenderness, crispness, and high edible quality. 
Therefore, the land must be highly fertilized and moist. In 
Florida about one ton per acre of 4-7-5 fertilizer is commonly 
used for the Boston, Romaine and leaf types, where 800 to 
1200 pounds per acre of a 3-8-8 fertilizer is recommended for 
the Iceberg type. Broadcast the seed on good moist seedbeds 
that have been thoroughly prepared, or sow in rows six inches 
apart and use a light roller to press seed into soil. A pound of 
seed sown broadcast plants a bed three feet by a hundred yards. 
Place burlap or well-washed old fertilizer sacks over the beds 
until seeds sprout. Old fertilizer sacks must be thoroughly 
washed before using to prevent burning of seed sprouts. Be 
sure seedbeds are kept thoroughly moist at all times after the 
seed is planted. In hot weather germination may be hastened 
and improved by placing moistened lettuce seed in moist cloth 
in the ice box for several days before sowing. In level culture, 
lettuce plants are usually set 15 by 15 inches in the field, or in 
rows 11% to 2 feet apart, and 10 to 15 inches in the row, or in 
double rows 16 inches apart, with 314 to 4 feet from center to 
center of double rows, and 14 inches in the rows. Plants should 
be watered as set in field. For insect control see page 54. 
Rusting of head lettuce and Romaine is usually due to boron 
deficiency. To prevent or stop this trouble, it is recommended 
to spray with | lb. borax to 50 gallons of water. This should 
be applied at the rate of not more than a total of 4 pounds 
borax per acre in two applications. ‘Too much borax is toxic. 
The number of days in parentheses after each variety repre- 
sents the time required to develop marketable heads from the 
planting of seed in seedbed or in the field or garden under 
average Florida conditions.

KILGORE’S MAMMOTH ROMAINE. (73 days.) Our Mam- 
moth Romaine is taller and much more vigorous and makes 
much larger heads with correspondingly heavier yields com- 
ared to other strains of Romaine or Cos lettuce. It can be left 
in the fields for 10 days to two weeks after it is ready to harvest 
without danger of bolting to seed. It forms firm, solid heads 
with the leaves well capped over the top. We have selected and 
re-selected this strain until it is very uniform in all respects. 
See second paragraph under “Culture” for control of rusting, to 
which this strain is somewhat susceptible.

DARK GREEN COS. (new). (70 days.) A large, self-closing, 
upright growing sort, with cylindrical or long loaf-shaped 
head with very dark green, slightly crumpled leaves. A big 
improvement over the old Paris White Cos for Florida growing 
conditions, being a sure header of larger size, firmer, better 
folded heads, and much more attractive in appearance and of 
excellent quality, being exceptionally crisp, tender and of 
endive-like flavor. A sure header under Florida growing 
conditions.

5 to 25 Ibs. $1.90 per Ib. 
SIMPSON, BLACK-SEEDED. (46 days.) The best large, very 
early, non-heading or leaf variety. The leaves are very broad, 
much blistered and crumpled, and excessively frilled on the 
borders, light yellowish-green in color, very tender, of fine 
delicate texture, and of excellent quality. .

5 to 25 Ibs. $1.99 per Ib. 
WHITE BOSTON (Ocoee Strain). (75 days.) This strain of 
White Boston was originated and developed in the Winter 
Garden section of Florida, and has been selected under Florida 
conditions for the development of a large framed lettuce 
similar to Big Boston. It produces larger heads, and bigger 
yields than any other strain of White Boston. 
Pkt. 10c; 0z. 20c; 14 Ib. 60c; 1 Ib. $2.00 
5 to 25 Ibs. $1.90 per Ib. 
BIG BOSTON. (75 days.) The heads are of cabbage or butter- 
head type, large sized, broad, slightly spreading, globular, with 
a broad shoulder at the base. The outer leaves are broad, al- 
most smooth, but wavy at the edge, medium light green with 
a tinge of brown on outer leaf margins. 
Pkt. 10c; 0z. 20c; 14 Ib. 60c; 1 Ib. $2.00 
5 to 25 Ibs. $1.90 per Ib. 
MIGNONETTE. (67 days.) An early maturing, exceedingly 
high quality, small, crisp head lettuce, not grown for com- 
mercial shipment, but useful for the Florida home gardener 
and for local markets because of its exceedingly high edible 
quality, being deliciously sweet-flavored, crisp and tender. 
Pkt. 10c; 02. 35c; 14 Ib. $1.00; 1 Ib. $3.50 
5 to 25 lbs. $3.40 per Ib. 
BIBB (Genuine Kentucky strain) (60 days.) A very distinct, 
small, early maturing, loose butter-head type lettuce, with 
thick, tender leaves of deep glossy green color, rich in vitamins, 
with a beautiful rich, creamy yellow interior head possessing 
superior crispness and delicious flavor. Recommended for 
home gardens and local markets where high edible quality is 
desired. Set plants only 6 inches apart because of their small 
size. 
Pkt. 10c; oz. 20c; 4 Ib. 60c; 1 Ib. $2.00; 5 to 25 Ibs. $1.90 per Ib. 
GREAT LAKES. (83 days.) The plants of Great Lakes are 
large, vigorous and have a distinctive, deep grassy-green, at- 
tractive appearance. Leaves are large, with rather deeply 
serrated margins, and very heavy midribs. The heads are 
relatively large, compact, firm and solid, with abundant wrap- 
per leaves which cover the heads, protecting them from cold 
and heat injury. Experience indicates that Great Lakes will 
stand higher temperatures, is much less subject to bottom rot, 
tip burn and slime rot, and does not bolt as readily as other 
varieties of this type. It offers a real possibility for prolonging 
the Florida lettuce growing season in late spring, and in early 
fall. This variety won a medal in the All-America selections 
of 1943. 
Pkt. 10c; 0z. 40c; 14 Ib. $1.15; 1 Ib. $4.00 
5 to 25 Ibs. $3.90 per Ib.
