GOOD VENTILATION IMPORTANT 
Lawn grasses grow better in extensive areas 
where the air has an opportunity to move freely 
across them than in restricted and poorly venti- 
lated locations. To wall in a lawn area or plant 
a heavy screening border of shrubs, which fre- 
quently reaches to the bottom branches of an al- 
ready existing circle of trees, is to shut out the 
beneficial air currents which dry the grass of dew 
before the heat of day and aid in proper cooing 
of the plants. Under such conditions a general 
weakening of the grass may always be expected 
and in very hot and humid periods during the 
summer it is usual for damage due to overheating, 
scald, brown patch, and leaf spot to be much more 
severe than in areas where ventilation is not inter- 
fered with. 
A beautiful lawn does 
not just happen—it is 
made with good seed 
and years of proper 
care. 
A WISE PRECAUTION 
The incorporation of the correct Permalawn 
Plant Food in the seed bed before sowing will 
cause the young plants to grow vigorously and 
lessen the danger of damage from heat for the 
spring seeding and of winter injury for the fall 
seeding. This simple precaution may mean the 
difference between success and failure. 
SEED LIGHTLY 
It is better to sow too little seed than too much, 
with its resultant crowding-out of the desirable 
turf grasses. Permalawn Seeds should be seeded 
at the rate of 4 pounds per 1000 square feet in 
sunny areas, 5 pounds per 1000 square feet in 
semi-shady areas, and 6 pounds per 1000 square 
feet in shady areas.
