PEARLWORT 



TT) EARLWORT is a small, grass-like annual which grows so 

 -/close to the ground that mowing will not prevent its 

 seeding. It is found in circular patches, which should be cut 

 out as soon as they appear, as the plant spreads rapidly. 



PENNYWORT 



Z'he leaves of Pennywort resemble those of the well 

 known ground ivy. Like the latter it must be dug up. 



MOSS ^ 



Jl/Toss is seldom troublesome in greens, perhaps because 

 -* rJ. they are usually well drained and well fertilized. On 

 the fairways it may be found in shaded or undrained places 

 and on poor soil. It has been generally thought that the 

 proper treatment of infested ground is a liberal application 

 of lime, but recent investigations have shown that moss will 

 grow on neutral as well as acid soil. Where Kentucky Blue- 

 grass grows it is well to use lime, first scarifying the surface. 

 Lime may help to run out the moss and it will at least stim- 

 ulate the Blue-grass. It may be impracticable to attempt 

 drainage, but the soil can always be enriched by top-dress- 

 ing. 



PO A ANNUA - 



77< ARLY in the spring. Annual Blue-grass, because of its 

 X2/ pleasing appearance attracts considerable attention. It 

 disappears in early summer. By some it is regarded as a de- 

 sirable plant for the green, but in most sections of the country 

 is treated as a weed. No matter how closely it is clipped, 

 Poa Annua will produce seed, and it will increase each year 

 if left alone. It is said that Creeping Bent will eventually 

 crowd out Poa Annua.
