growth of the plants daily. Hybrid tea 

 roses required for forcing can be treated in 

 a similar way, with the exception that the 

 ripening process must not be too severe, as 

 hybrid teas are more tender than H. P. 

 varieties. 



Plants of Hydrang-ea otaksa and similar 

 varieties of these useful half-hardy plants 

 will require the protection of a shed or out- 

 house for a few weeks before severe frosts, 

 previous to being placed in their winter 

 quarters in the basement or cellar, or under 

 the greenhouse benches. The pretty little

free flowering hardy shrub, Deutzia gracilis, 

 succeeds splendidly in the greenhouse in 

 winter. Plants of this dwarf growing 

 Deutzia can be taken up from the open 

 ground, potted into ordinary potting soil, 

 and in February or March will develop a 

 wealth of their snow-white blossoms, with 

 very little care and attention. Fancy 

 caladiums. Tuberous begonias and gloxinia 

 bulbs can be dried off gradually and placed 

 away in their winter quarters. The cala- 

 dium bulbs will probably winter best if left 

 undisturbed in the pots, and the pots can 

 be laid on their sides under the graenhouse 



bench, not too near the hot water or steam 

 pipes, however, to dry them out too 

 severely. Rats and mice must be guarded 

 against, as these unwelcome visitors are 

 very partial to a banquet of high-priced 

 caladium bulbs. Tuberous begonia or 

 gloxinia bulbs can either be left in the pots 

 and stowed away in a dry place in a 

 temperature about 45°, or the bulbs and 

 tubers can be shaken out from the pots, 

 after all growth has ceased, packed away in 

 sand or dry soil in boxes, and placed in any 

 fairly dry, cool place, free from frost. A 

 temperature of 45° to 50° will suit them 

 very well. 



If seedling cinerarias, calceolarias, or 

 plants of pelargoniums, are sttU out in cold 

 frames, careful watch must be kept on 

 them, for, although these plants like a cool 

 temperature, a very slight freezing injures 

 them permanently. Violets that have been 

 kept outside should be brought into the 

 greenhouse if required for early flowering 

 purposes, or they may be left out until later, 

 or even until spring, if a sash is placed 

 over them, and a little care and attention 

 given them during the winter. Roses 

 planted out on benches should be allowed 

 to produce their flowers now as freely as 

 possible. The disbudding of chrysanthe- 

 mums, as mentioned in September number 

 of Journal, will have to be attended to as 

 required. 



If mildew appears on roses or chrysan- 

 themums, paint the steam or hot water 

 pipes with a thick paste of flour of sulphur 

 well mixed with water. Apply this mixture 

 to the pipes, and on a chilly night, when a 

 little extra heat will not hurt the plants, get 

 up a good circulation of heat in the pipes 

 sufficient to raise a strong suliphury smell 

 through the greenhouse. If this extra 

 heating process is repeated about once a 

 week until more severe weatheT, it will 

 eff"ectually prevent the spread of this 

 dreaded fungous disease. Sulphur must
