FOOD FOR PLANTS 71 



Frequent rolling is of great advantage, as well as 

 frequent raking. Every lawn in the spring should 

 be subjected to a searching inspection for weeds. 

 Early spring is the time for the heavy annual top- 

 dressing of fertilizers. . 



Two or three weeks after the application of fertil- 

 izers, a mixture of lawn grasses may be sown and 

 covered with a thin layer of finely sifted soil and then 

 rolled down. Rolling should not be continually in 

 one direction, but should be changed. 



If young grasses are growing amongst the old, it 

 will be an advantage to keep the lawn closely cut. 



By this practice roots are strengthened and the 

 density of the turf increased. In sowing lawn seed, 

 sow half the quantity going north and south, and half 

 east and west. 



Grass which has become brown or yellow may be 

 watered or treated with Nitrate of Soda and the 

 green color thus restored. Lawns may safely be 

 given applications of Nitrate whenever the sickly 

 green color of the grass appears, as this shows that 

 Nitrogen is the food needed. Finely sifted soil ob- 

 tained from decayed leaves is the best treatment for 

 lawns to provide them with humus. 



Our Formula for Meadows, Lawns and Golf Links. 



Nitrate alone 100 lbs. per acre 



or preferably 



Nitrate 200 lbs. per acre 



Acid Phosphate 200 lbs. per acre 



When potash salts can be conveniently obtained 

 we advise the use of fifty pounds of sulphate or 

 muriate of potash to the acre every other year.
