wash the foliage, Burning due to fertilizers, sometimes 
may be avoided or materially reduced by mixing the 
fertilizer with 2 or 3 times its volume of screened soil. 
LIMING—Most lawns will require a topdressing of 50 
to 75 pounds of ground limestone per 1,000 square feet 
every 2 or 3 years. This is best applied during the 
Fall or early Spring. 
ROLLING—The primary purpose of rolling turf is to re- 
establish contact between the soil and the roots of 
grasses that have been lifted by heaving. The opera- 
tion helps to maintain a smooth surface, but one 
should not attempt to level the lawn by using a heavy 
roller, since this is likely to pack the soil too greatly. 
Where leveling is required the low places should be 
filled with loam. 
WATERING—Sprinkle the lawn only when it is actu- 
ally suffering from a lack of moisture. Soak to a depth 
of 2 or 6 inches. No further moisture should be needed 
for several days. 
Frequent light sprinklings compact the soil and are 
of more benefit to summer weeds than to the lawn. 
GRUB PROOFING—An initial application of DDT to 
the seedbed should control grubs for several years. 
About every 4 or 5 years an additional treatment of 
DDT at the rate of 10 pounds per 1,000 square feet of 
lawn should be made. It may be topdressed uni- 
formly over the surface of the soil. 
RIDDING YOUR LAWN OF WEEDS 
The best way to control weeds is to grow a thick, 
healthy lawn. The practices of liming, fertilizing, mow- 
ing, watering, etc. as discussed are your best guide 
to doing this. Should your lawn suffer from weed 
infestation there are some good treatments for elim- 
inating the pests. 
BROAD-LEAVED WEEDS—Such weeds as dandelion, 
buckhorn plantain, ground ivy and many others are 
easily destroyed with 2, 4-D weed killer. This material 
is cheap, efficient and non-injurious to the grasses. 
See your Doughten Seed Company Dealers for a 
supply. The 2, 4-D will not kill crab grass. 
CRAB GRASS—This is the most difficult lawn weed to 
control. Good management is the best answer. Ferti- 
lize regularly in the Fall and early Spring to stimulate 
the good grasses when the crab grass is dormant or 
has not begun to grow. Mow no closer than 1}/, inches 
and water only as needed.
