Jan.~\ GREEN-HOUSE CAMELLIA JAPONICA. 



OF WATERING. 



In this month very little is requisite, and must be given 

 with great caution. Few plants will require much, and 

 some hardly any; but all must be attended to, and have 

 their wants supplied. Some will need it twice, some once 

 a week, and some in two weeks, according to their shrubby 

 and woody nature. Herbaceous and deciduous plants will 

 seldom need water. Perhaps, from the shedding of the 

 foliage to the commencement of vegetation, three or four 

 times will be sufficient. Particular attention should be 

 paid to the state of health and of growth, in which the 

 plants respectively are, in the application of water; other- 

 wise much mischief may be done, and many entirely 

 ruined. 



Green-house plants being now in an absolutely inactive 

 state, require little more water than merely to keep the 

 earth about their roots from becoming perfectly dry, by 

 occasionally applying a very small quantity at the root ; 

 and, if done with a watering-pot, as described under this 

 head in the hot-house of this month, very little will be spilt 

 in the house to increase dampness, which, if it does appear, 

 by any of the leaves of the plants becoming musty, they 

 must be instantly picked off; and, if it increases, give a 

 little fire and air." Succulent plants will not need any water 

 during this month, unless omitted in December. 



CAMELLIA JAPONICA. 



This magnificent and attractive flower, with all its 

 splendid varieties, will, about this time, begin to open its 

 beautiful flowers. But for this admired genus of plants, 

 our green-houses, at this season, would be void of allure- 

 ment. It is, in this country, subject to red spider, and 

 more especially in the city, which appears to be from the 

 nature of the air. The effects of the spider on these plants, 

 if not prevented, would prove fatal ; as, from appearance, 

 many have died by it in several collections. If it has 

 reached a great extent, the leaves are brownish, having the 

 appearance of being decayed, or scorched with the sun.
