nitrogen per 1000 square feet per month. Translated 
into commercial fertilizer standards, 8 to 16 pounds of 
a 6% nitrogen fertilizer or 21 to 5 pounds of a 20% 
nitrogen plant food would be required. It may be nec- 
essary to use a carrier such as water, sand or loam to 
apply the above quantities evenly over 1000 square 
feet. High nitrogen water soluble plant foods can best 
be applied in liquid form. During hot summer months 
use organic fertilizers. See your dealer for advice and 
equipment. 
Fertilizers may be applied in liquid or granular form, 
but should be thoroughly watered immediately after 
application. Frequent light applications will minimize 
the danger of burning your lawn. Do not apply dry 
chemical fertilizers to grass that is wet, either from dew 
or from watering. Apply dry chemical fertilizers to dry 
lawns. Then water well. 
WATERING — It is very important to maintain the 
proper moisture conditions for your lawn. Excessive 
or inadequate watering is equally harmful. The best 
method of irrigating your lawn is to thoroughly soak at 
one watering, being sure moisture penetrates to a depth 
of at least six inches. A good mechanical sprinkler is 
recommended, as hand watering about homes usually 
means hasty and inadequate watering. Generally speak- 
ing, one inch of water will penetrate the soil to about 
six inches. You may determine how long it will take 
your sprinkler to carry this much water to the soil by 
using several empty coffee cans, placed in a line from 
the nearest to farthest reaches of sprinkler on the lawn 
to catch water. In this manner you can determine 
whether or not your sprinklers are delivering equitable 
amounts of water to your lawn, or you can plug your 
lawn as you would a watermelon, replacing the plug, 
to determine how far down your watering operations 
had carried. By using this method, in a relatively short 
time, you will be able to determine, within minutes, 
the length of time required to soak your lawn to the 
desired depth. 
Without question, frequent shallow watering is the 
cause of more lawn troubles than most any other single 
reason. Roots will follow moisture and once the root 
system has been developed to a depth of at least six 
inches you will save on your water bill by virtue of less 
frequent irrigations and less water wasted. 
INSECT CONTROL — The most common 
lawn insect is the Lawn Moth or Sod Web- 
worm. Gray moths usually visible at dusk, 
fly low over the lawn when infestation oc- 
curs. Since prompt remedial action ts essen- 
tial, the following test to determine the 
presence of Sod Webworm should be 
made. Thoroughly water the affected area 
and then apply a pyrethrum or lindane solution around 
the outer edge. If Sod Webworms are present they will
