Lawns 



and the nature of the existing conditions. On a 

 lawn we usually place the plants we desire, by using 

 turf containing grasses suitable for the purpose, 

 or by sowing a mixture of seeds free from weeds. 

 If the conditions are favourable to the grass all goes 

 well, but if they are unfavourable and bare patches 

 arise, weeds and moss are apt to estabhsh themselves ; 

 and if the conditions are then more favourable to 

 the weeds or the moss, the grass will gradually be 

 killed out and its place taken by the more favoured 

 tribe. 



The application of sulphate of ammonia favoiirs 

 the growth of grasses more than does any other 

 manure. It also acts detrimentally upon broad- 

 leaved plants if strewn upon them, and where time 

 permits there is no better method of killing them 

 than by putting as much sulphate of ammonia on 

 their crowns as would cover a sixpence. Where this 

 cannot be done sulphate of ammonia should be dis- 

 tributed over the lawn at the rate of IJ cwt. to the 

 acre (^ oz. to the square yard, or 1 lb. to the square 

 rod). It may be mixed with dry soil and spread 

 more readily thus than by merely throwing it on 

 broadcast. More should not be used and may do 

 harm. Spring is the best time to apply the manure. 



The presence of moss is a symptom that condi- 

 tions are not favouring the grasses. At least three 

 different causes may lead to the production of this 

 symptom, viz. lack of drainage, sourness of soU, and
