Gardening in Californi 



enough to be pulled up, especially those weeds which have per- 

 ennial roots such as the Thistle, the Dock and the Dandelion. 

 On no account should the Dandelion be allowed to seed. It 

 must be eradicated at once, because if only one flower-stalk or 

 head is allowed to ripen its seeds, it will completely ruin a lawn 

 in a short period. There are myriads of seeds in one of these 

 flower-tops, and when they are allowed to spread they spring up 

 in a few days and do an immense amount of damage. 



When the soil is of brown loam or black dobe, the 

 treatment above suggested applies equally well, but it must 

 be kept in view that should the soil be brown friable loam 

 naturally well drained, all that is necessary at the beginning is 

 to grade the ground in the shape desired, and, instead of, as in 

 the case of clay soil, trenching two feet deep, digging one foot or 

 one spade in depth will be enough. The applying of manure 

 and the rest of the work should be done as advised in the case 

 of clay soil. 



If the natural soil of the site, where the lawn is to be, is poor 

 sand, this sand must be removed to the depth of at least one foot 

 and replaced with good loam. The loam should then be manured 

 and the rest of the work done exactly in the same way as recom- 

 mended for the other soils.
