PERFEGRO LAWN GRASS SEED 
HOW TO BUILD A NEW LAWN 
PLANTING TIME—Spring, Summer and Fall. 
SOIL PREPARATION—Cultivate to a depth of 6 to 8 in. with 
garden fork, rototiller, or tractor cultivator; soak heavily 
to settle clods. Pulverize surface with garden rake and form 
smooth, level seedbed. Sprinkle, allow 10 to 12 days for 
weed seeds in newly upturned soil to sprout. 
‘FERTILIZING—Apply lawn food at the same time lawn is 
. 
seeded. High-analysis lawn fertilizer should be applied at 
16-20 lbs. per 1,000 square feet. 
SEEDING—Kill sprouted weed growth with light raking. Apply 
at 1 lb. per 250 sq. ft. Rake seed lightly into the soil. An even 
coat (about 1-4 in. thick) of peat moss or weed-free straw 
spread over the lawn will help your seed sprout better and 
faster. Firm surface with a lawn roller or wide board. 
SOWING TiP—Empty half of seed into container. Mark out 
area to be seeded. Sow half of seed lengthwise to area. Take 
handful of seed, walk slowly forward, swinging arm in wide 
arc, letting seed flow through fingers. Repeat with remaining 
half across area. 
HOW TO REPAIR AN OLD LAWN 
Turn over bare spots to a depth of 4 to 6 in., adding a good 
fertilizer and a good loam soil if possible. Rake surface evenly, 
seed at same rate listed above, firm ground with a roller, 
unless your soil is heavy clay or adobe, then keep well watered 
until seedlings are well rooted. Don’t let newly seeded spots 
bake or dry out. To repair thin lawns, vigorously rake the soil 
surface to prepare the seedbed. Seed at the same rate listed 
above and cover lightly with rich top soil or peat moss. Water 
carefully and keep the surface moist until the seedlings be- 
come well rooted. 
KENTUCKY BLUE GRASS—Special Recleaned Seed—This is 
the most widely used grass for Lawns; forms a close, thick

off weed attacks, and crowds out crab grass. Holds its color 
well in hot weather, even with a minimum of water. Its dense 
compact turf stands up to hard wear and abuse. Sow one 
pound of seed to 500 to 750 square feet of lawn area.

over the ground and send down roots from their joints. It is 
very fine bladed and forms a thick velvety turf. It is quick 
growing and crowds out dandelions and other weeds. Sow 
one pound to 300 square feet.

COOS OR’SEASIDE BENT—This variety differs only from the 
Astoria Bent in that it creeps more on top of the ground, 
thus forming, when it has been well established, somewhat 
of a turf or matting on top of the soil which tends to crowd 
out weeds. Postpaid—Lb. $1.75, 5 Ibs. $8.50, 10 Ibs. $16.50. 
FACTS ABOUT WEEDS 
Any New Lawn Has Weeds! Because they are slower grow- 
ing at first, fine lawn mixtures are sometimes weedier at first 
than cheap, fast-growing mixtures. Don’t let early weediness 
discourage you! After grasses get established, they gradually 
choke out most weeds. Others can be controlled with weed 
killers. By the end of the first year, your lawn grows so thick 
it crowds out most weeds. 
HIGHLAND BENT—This grass produces a luxuriant, heavy and 
very firm turf, it is of fine texture, hardy and very resistant

ent to any lawn seed mixture.

BUFFALO GRASS FOR LAWNS—Treated to hasten germina- 
tion. This is a low-growing long-lived drought-resistant peren- 
nial grass that spreads by numerous surface runners. Pro- 
fuse branching of runners enables this grass to form a dense 
sod. The leaf surface is a gray green, turning to purplish in 
late fall. Seed should be applied at the rate of from % to % 
pound per 1,000 square feet of lawn area. The seeding rate 
is readily obtained by spacing the seed % to % of an inch 
apart in the rows, or by dropping 15 to 20 seeds per foot of 
row, in rows one foot apart. After the lawn is up requires 
very little water, making it an ideal grass for farm lawns, 
parks and cemeteries.
