138 GARDEN PLANTS. PART II. 



requiring so much room, may be put out somewhat nearer to 

 one another. 



Knol-kohl takes about six weeks or two months to arrive at a 

 state fit for the table, and is always most acceptable, as being 

 the earliest European vegetable of the season. If allowed to 

 grow to a great size it becomes hard, woody, and strong in 

 flavour. It is in its best condition when about the size of a 

 tennis-ball. The upper half of the vegetable is always the 

 most tender. 



Brassica Rapa. 



TURNIP. 



Selgum. 



There are several varieties of the Turnip, both of the white 

 and of the yellow. Kemarkably fine specimens of many of 

 these are raised in this country, but they mostly have a strong 

 and rather acrid flavour, rendering them far from agreeable. 

 For cultivation, therefore, the earliest sorts would be the more 

 desirable, being quickest in growth and of mildest flavour. 

 None, perhaps, will be found to surpass the Whitestone. 



The time to commence sowing the seed is about the middle 

 of October. The sowing may be made broadcast ; and in order 

 that it may be done evenly, which is of great importance, the 

 seed should be mixed with about four times its bulk of dry 

 silver-sand. But the better plan, perhaps, is to sow it in drills, 

 about a foot apart, and then at the very earliest stage of their 

 growth to hoe out the seedlings to the distance of a foot from 

 each other. Nothing can be more injurious to the plants than 

 to allow them to be in the least crowded, for in that case they 

 expend themselves in leaves, without forming bulbs. 



The soil, which before the sowing should be well dug up, 

 ought to be of a light quality, but not recently manured. 

 The plants require to be abundantly watered to promote rapid 

 growth. 



Sinapis alba. 



MUSTARD. 



Edee. 



Scarcely any directions can be required for the cultivation 

 of Mustard. The seed, sown broadcast and very thickly in a
