LETTUCE 
Sow % to 1 pound in seed-bed to plant an acre, or plant 1 to 14% pounds per acre in field. 
For the garden make two plantings at different times. Sow 1 packet in a protected seed-bed 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. 
Cutture. 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 this crop, except the Imperial type, where 
800 to 1200 pounds per acre of a 3-8-8 fertilizer is recom- 
mended. Broadcast the seed on good moist seed-beds that have 
been thoroughly prepared, or sow in rows six inches apart and 
use a light ruller to press seed into soil. A pound of seed sown 
broadcast jlants 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 seed 
beds are kept thoroughly moist at all times after the seed is 
planted. In hot weather germination may be hastened and im- 
proved 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 
1% to 2 feet apart, and 10 to 15 inches in the row, or in double 
rows 16 inches apart, with 344 to 4 feet from center to center of 
double rows, and 14 inches in the rows. Plants should be 
watered as set in field. 
Rusting of head lettuce and Romaine is usually due to boron 
deficiency. To prevent or stop this trouble, it is recommended 
to spray with 1 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 named 
represents the time required to develop marketable heads from 
the planting of seed in seed-bed or in the field or garden under 
average Florida conditions.

IMPERIAL NO. 44. (82 days.) This variety is exceedingly 
slow to go to seed, even if started in hot weather or early fall, 
or if grown in yery late spring in Florida. It is one of the 
safest varieties of the Iceberg type from the standpoint of high 
temperature tolerance. It matures slightly earlier, makes slight- 
ly smaller, flatter and broader heads than Great Lakes. To get 
good size requires somewhat heavier fertilization than Great 
Lakes. It produces exceedingly solid, hard heads, of high 
quality over a long season. It is especially well suited for Flor- 
ida muck-land culture.

GREAT LAKES. (83 days.) This variety of the Iceberg 
type lettuce was introduced by us to Florida growers. As a 
result of commercial trial plantings in different sections vf 
Florida, this variety shows much promise, especially as a late 
spring hot weather variety. In our comparative trials it con- 
sistently cut a higher percentage of marketable heads than 
No. 44. The plants of Great Lakes are large, vigorous and have 
a distinctive, deep grassy-green, attractive appearance. Leaves 
are large, with rather deeply serrated margins, and very heavy 
midribs. The heads are relatively large, compact, firm and 
solid, with abundant wrapper leaves which cover the heads, 
protecting them from cold and heat injury. Experience indi- 
cates 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 No. 44. It can be planted earlier—before 
September 25th, and later—after December, than can be No. 44 
in Central and South Florida. It offers a splendid possibility for 
prolonging the Florida lettuce growing season in late spring, 
and in early fall. Our trials indicate this variety does as well 
or better than other varieties of this type throughout the entire 
lettuce planting season in Florida. This variety won a medal in 
the All-America selections of 1943, which is conclusive evidence 
of its superior characteristics.

5 to 25 lbs. $5.40 per lb. 
OCOEE WHITE BOSTON. (75 days.) This strain of 
White Boston was originated and developed in the Winter Gar- 
den section of Florida, and has been selected under Florida 
conditions for the development of a large framed lettuce simi- 
lar to Big Boston. It produces larger heads, and bigger yields 
than any other strain of White Boston. 
Pkt. 10c; oz. 20c; 14 Ib. 60c; 1 lb. $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, globu- 
lar, with a broad shoulder at the base. The outer leaves are 
broad, almost smooth, but wavy at the edge, medium light 
green with a tinge of brown on outer leaf margins. 
Pkt. 10c; oz. 20c; %4 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, it being deliciously sweet flavored, crisp and tender. 
Pkt. 10c; oz. 35c; %4 Ib. $1.00; 1 Ib. $3.50 
5 to 25 Ibs. $3.40 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. 
Pkt. 10c; oz. 20c; %4 Ib. 60c; 1 Ib. $2.00 
5 to 25 lbs. $1.90 per Ib. 
ROMAINE (WHITE PARIS COS OR TRIANON COS). 
(66 days.) This variety forms a large, medium green, well- 
folded head with blunt top, and when properly grown it is 
very sweet, crisp, mild, and of fine quality. 
Pkt. 10c; oz. 20c; %4 lb. 60c; 1 lb. $2.00 
5 to 25 Ibs. $1.90 per Ib. 
KILGORE’S MAMMOTH ROMAINE. (73 days.) Our 
Mammoth Romaine is taller and much more vigorous and makes 
much larger heads with correspondingly heavier yields compared 
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 
reselected 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. 
Pkt. 10c; oz. 20c; 4 Ib. 60c; 1 Ib. $2.00
