REQUIREMENTS OF PUTTING GREENS I55 



is to systematically go over the entire green 

 every season and cut them out with a sharp 

 knife as far down at the roots as possible. 

 And the same way with crab or summer 

 grass. This treatment, faithfully pursued 

 for a season or two, followed by careful seed- 

 ing, will make it almost impossible for weeds 

 to find a lodgment. 



WATERING 



"During the hot and dry summer months 

 the greens should be thoroughly soaked at 

 least twice a week by letting the water run 

 through a revolving sprinkler. If necessary 

 keep the water going all day, moving the 

 sprinklers from time to time. Watering in 

 this way, even under a hot sun, is infinitely- 

 better than just wetting the surface in the 

 evening. The latter practice, in point of 

 fact, does more harm than good, as it results 

 in the roots of the grass bunching themselves 

 close to the surface — ^the only place where 

 the moisture is — instead of boring down, as 

 they should. Therefore don't be afraid to 

 soak a green. No injurious effects will 

 come from the hot sun pouring down its rays
