use will depend upon the variety and the length of the season. 

 The earlier maturing the variety, the later it can be planted; 

 and the farther north the locality, the earlier the planting may and 

 must be done. The cool nights of the northern summers are espe- 

 cially favorable to the growth of root crops, cabbage, celery, 

 etc., so that it is feasible to grow a larger assortment of vege- 

 tables for storage in the North than in the South. It is fortunate 

 that such is the case, for in the South, vegetables can be grown in 

 the winter, while in the North, storage is a much more important 

 factor in the winter supply. 



In central and northern localities, the dates for planting the 

 vegetables designed for \\inter use would be about as follows: 



1. Onions (for either summer or winter use), as early as the 

 ground can be worked in spring. Onions differ from all the other 

 vegetables stored for winter in that they must be ripened and 

 cured while the weather is still warm. The earlier they are planted, 

 the surer the crop. 



2. Parsnips, salsify, horse-radish, and leeks would be planted 

 about the same time as onions, for, although an extremely early 

 start is not so imperative in the case of these vegetables, they 

 demand a long season to complete their growth, and the earlier 

 they are started, the longer the time they will have to grow. 



3. Beets and carrots, late varieties. May 1 to May 15; early 

 varieties, June 1 to June 15. Plantings made in May are surer 

 to make a crop than those made in June; hence the late varieties 

 are the more reliable. 



4. Rutabagas are not adapted to hot climates, and hence are 

 seldom grown in central and southern localities. In the North 

 they should be planted from June 15 to July 1. 



5. Cabbage, Brussels sprouts, and celery (transplanted), July 1 

 to July 15. 



6. Turnips, winter radishes, and kohlrabi, July 20 to August 10. 

 The other crops suitable for storage would be planted at the 



same time, whether intended for immediate use at maturity or 

 designed to be stored for winter. 



Conditions Essential to Successful Storage. — Of the vegetables 

 stored for winter, some require entirely different conditions in 

 storage than do others, so that attempts to store all vegetables 

 under the same conditions would result only in failure. In order 

 that root crops may be stored without wilting, rotting or starting 

 into growth, they must be kept cool, fairly moist, and away from
