ROLLING 
Rolling should be done in early spring when soil is damp. Usually 
the time when rolling can be dope effectively is limited to one or two 
days* The ground settles quickly and after it becomes compacted rolling 
does little good. Rolling when sod is too wet is detrimental* 
FERTILIZING 
Below is a schedule to apply a good lawn fertilizer having an 
analysis of 10-6-4 or similar analysis. 15-26 lbs. in March or April, 5- 
6 lbs* in June, 5-6 lbs- of Bone Meal in October* 
In dry weather soak well once a week. Light watering promotes shallow 
root development which is not desired for a permanent lawn* 
MOWING 
In Spring and fall the cutter bar of the lawnmower should be raised 
up so that the grass does not get cut too short* The reason for this is 
that in spring the top of the grass plant must be let grow if we are to 
have good root development. In the fall the grass which is not cut helps 
to protect the roots thru cold weather. In summer the grass should be cut 
often enough so that the clippings can be left on without being noticeable* 
It will require two or three cuttings per week thru June to make a healthy 
turf look attractive. If for any reason the grass does become tall the 
clippings must be removed or severe burning will result often killing the 
roots completely. The reason for leaving the clippings on the lawn is that 
they add fertility to the soil and protect the roots from the hot sun and 
add organic matter- WEEDS 
Follow suggestions made under section headed "Rejuvenating Old Lawns". 
Crab Grass, ground ivy, chick weed and narrow leafed plantain are hard to 
combat. When found they usually are so thick that digging seems impossible. 
Sodium Chlorate broadcast over the infected area will turn all the weeds as 
well as the grass brown but it has been found that the grass will live thru 
and in a short time green up with practically all weeds eliminated. The 
treatment of Sodium Chlorate is about the only way to combat ground ivy and 
chick weed. Plantain and crab grass spread thru seeding. If lawn is kept 
clipped regularly the seed does not get a chance to mature and control can 
be effected. In all weed control remedies it usually takes more than one 
season to bring about results. 
PESTS-EARTHWORMS 
Two ounces of bichloride of mercury dissolved in fifty gallons of 
water and sprinkled to 1000 sq* ft- is a good remedy or mix two ounces of 
bichloride of mercury with two Cu. Ft- Sand and scatter over 100 Sq. Ft* 
Surface. Sprinkle thoroughly after either of the above applications are 
made- Bichloride of mercury is a poison and care should be exercised in 
keeping the fowls or birds from eating the dead worms- 
ANTS 
With the aid of an oil can squirt carbon bisulphide in to the ant 
holes. Cover opening with damp earth or blanket. If necessary make holes 
nine or ten inches deep where no opening can be found- Repeat treatment 
every week until ants disappear. 
MOLES 
Moles may be trapped with a special mole trap or poisoned with Calcium 
Cyanide placed in their runways at short intervals of 8-10 feet, all open¬ 
ings covered with moist earth Care should be taken in using calcium cyanide 
as it is a poison.
