ROTATION OF CROPS. OO 



In these rotations it is not necessary to apply manure 

 to every crop. For the bulbous roots, as the onion, and for 

 plants cultivated for their leaves, as spinach and aspara- 

 gus, the ground can scarcely be too rich; and the bulk of 

 the manures may be applied- to them and the cabbage and 

 turnip crops, while for plants raised for seed it is best 

 that the foliage should not be stimulated into too great 

 luxuriance by fresh manuring. 



In practice these rules should, as far as possible, be fol- 

 lowed, but it is often necessary to vary from them or let 

 a part of the soil lie, for a time, idle. Rotations in gar- 

 dening become less necessary if the ground is plowed 

 deeply and manured highly. Vacant ground thus treated 

 may be filled at once with any crop ready for planting. 



To get the highest possible results from a garden, there 

 must be not only a general rotation of crops year by year, 

 but a number of sub-successions each yeai'j as fast as the 

 crops are removed. One-fourth of an acre thoroughly 

 manured and kept perfectly free from weeds, upon which 

 a constant succession of crops is kept up, will yield more 

 than an acre managed in the common way. It is not, 

 however, always necessary to wait until the crop occupy- 

 ing the soil is removed before another is put in. Simul- 

 taneous cropping — that is, making two crops occupy the 

 ground at the same time, as in field culture the cowpea 

 in corn-fields — can often be resorted to in the kitchen 

 garden. In the fruit garden, De Candolle says the vine 

 and the peach can with advantage be grown together, the 

 light shade of the peach not injuring the vines. 



Directions to meet all circumstances cannot be given, 

 still the following hints may be suggestive of the best 

 methods to secure in the kitchen garden satisfactory 

 results: 



For instance, in the fall a portion of the garden may be
