WINTER TREATMENT. ^ 



boards or slates. By this plan I have caused the DendroUum 

 speciosvm to flower, but this must be doue with caution and care 

 before the heavy rains set in. 



WINTER TREATMENT. This season commences about the 

 middle of October, and continues till the end of March. During 

 all this time the plants must be carefully watched. Should any 

 appear to shrivel very much, they must have a small quantity of 

 tepid water to just keep them, both roots and stems, in a fresh 

 state. Terrestrial Orchids should have their decayed leaves 

 removed, and be placed where no water can reach the soil in the 

 pots. The earth though apparently dry will be moist enough to 

 keep the bulbs alive arid fresh. As soon as the spring arrives, 

 then get ready all the necessary soils, and, when required, fresh 

 blocks and baskets, and proceed to repot, reblock, and rebasket 

 the whole collection as soon as the symptoms of fresh growth are 

 perceptible. Give the interior a good cleansing, and also sponge 

 the leaves and stems quite clean. This will end the winter treat- 

 ment, and then commence the summer season. 



As I intimated in the commencement of these papers, I shall 

 now give a list of such Orchids as will grow in a greenhouse 

 temperature. My space will not allow descriptions of the species, 

 I can only give their names. If the amateur desires to see that, 

 he must consult larger works on that point. I may here observe, 

 that most of the Orchids that are found in Guatemala, New 

 Holland, China, and other temperate climes, are proper denizens 

 of our greenhouses.
