Infected plants purchased from a clubroot seed bed might be the 

 means of contaminating one's cabbage land with the disease. Club- 

 root is a persistent malady. It will remain in the soil for five to 

 seven years. Land so infected should not be used for cabbage, 

 turnips, rape, mustard or any other plant of the cabbage family. 

 The rotation of crops to the exclusion of all cabbage-like plants 

 for a term of years is the only safe way of ridding the land of 

 the disease. This applies with equal force to both seed bed and field. 

 There is no satisfactory remedy known except the following "don'ts: " — 



(1) Don't sow cabbage seed on soil infected with clubroot. 



(2) Don't plant plants grown in a clubroot-infected seed bed. 



(3) Don't use manure containing roots of cabbage infected with 

 clubroot on ground intended for the culture of cabbage or any of its 

 close relatives. 



(4) Don't plant cabbage on an infected field within six or seven 

 years after the diseased crop has been harvested. 



(5) Don't grow turnips, rape, mustard or other cabbage-like plants 

 on clubroot-infected soil unless you wish to perpetuate the disease. 



Cauliflower. 



Cauliflower is always grown as a market-garden crop or for home 

 use, never in any sense as a farm crop. Practically everytliing that 

 has been said in regard to cabbage, as to soil, fertilizers, growing of the 

 plants, preparation of the soil, planting and cultivation, applies with 

 equal force to cauliflower. The only exception worthy of note is that 

 cauliflower may be set somewhat closer in the row than cabbage, but 

 the practice of growers varies, and many set at practicalh' the distance 

 apart recommended for cabbage in the foregoing. 



When the head begins to form the leaves should be drawn together 

 and fastened over the head, to keep the sunlight from it. Properly 

 sheltered the head will present the pure white appearance so much 

 admired in the market. If the sun is allowed to touch the heads after 

 they have begun to grow they will first turn green and later reddish. 

 No amount of bleaching will remove this color once it has been acquired; 

 the onlj'' way to prevent it is to act in time. The leaves should be 

 drawn together at the top, one at a time, overlapping each other, and 

 fastened together by a wooden pin or skewer, thrust through the leaves, 

 or thej^ may be tied together with raffia or any sort of twine. Both 

 methods are used, and with equal satisfaction, according to the prefer- 

 ence of the grower. 



Harvesting is controlled by the size of the heads and the state of the 

 market. The stalks are cut and the leaves trimmed off close to the 

 head. Some cauliflower comes into the market, in jNIassachusetts, in 

 August, but the greater part of the crop is marketed in September and 

 October.
