Weeds. 63 



Weeds in general, continued. 



thistles and other pests, particularly in dry years, but on 

 richer and retentive soils more thoroughness must be prac- 

 ticed 



2. Weeds in Lawns. Weeds usually come up thickly in 



newly sown lawns They are to be prevented by the use 

 of commercial fertilizers or very clean manure and clean 

 grass seed. Clean June-grass, 01 blue-grass, seed is 

 usually best. Grass seed should be shown very thickly 

 2 to 4 bu. to the acre and annual weeds cannot persist 

 long. Frequent mowings during summer will keep the 

 weeds down, and most species will not survive the winter. 

 In old lawns most perennial weeds can be kept down by 

 very frequent mowings with a good lawn mower Grass 

 can stand more cutting than weeds If mowing cannot be 

 practiced often enough for this purpose, the weeds may be 

 cut off below the surface with a long knife or spud, and 

 the crowns are then readily pulled out Or a little sulphuric 

 acid oil of vitriol may be poured upon the crown of each 

 plant 



3. Weeds on Walks. Walks should be so made that 



weeds cannot grow in them This can be done by making 

 a deep stone foundation and fillip between the stones with 

 cinders, coal ashes, or other similar material But when 

 weeds become established they can be destroyed by the 

 following methods 



SALT. Hot brine (i Ib. of salt to i gal of water), 

 boiled in a kettle on wheels and dipped out into watering 

 pots. Brine is better than dry salt, because it leaves very 

 little color upon the walk. 



LIME AND SULPHUR. 10 gals, of water, 20 Ib. of quick- 

 lime and 2 Ib flowers of sulphur are boiled in an iron 

 vessel , after settling, the clear part is dipped off and used 

 when needed. Care must be taken, as it will destroy 

 edgings
