also be removed to a drier and cooler place and water 

 given with the utmost care. 



At the beginning of the growing season the young 

 shoots of Orchids often rot. This is caused by drip or 

 by water settling upon them. At this season the greatest 

 care is necessary to prevent this, and it should be espe- 

 cially seen that the water from the hanging plants does 

 not fall on the young shoots of plants below. Young 

 flower stalks often damp off from the same cause. 



Orchids often suffer from a sour sodden soil, caused by 

 imperfect potting or deficient drainage, the result of long 

 deferred repotting. The remedy is to repot the plants. 



Spot is a disease which attacks the foliage, and soon 

 disfigures it. It is caused by too much moisture in cool 

 weather, and by exposing the plants to draughts and sud- 

 den changes of temperature. 



Prevention is far better than cure, .and if the rules for 

 potting and ventilation which we have prescribed are 

 followed, there will be no trouble from spot. Fresh air, 

 a sweet, moist temperature, clean, sweet, well drained 

 potting material, are perfect preventives of this disease. 

 Should a plant become infected it should be at once re- 

 moved from the pot, thoroughly cleaned, all dead roots 

 cut away, and repotted in fresh sweet material. 



Spot is not necessarily fatal. If remedies are applied 

 in time, the plants soon outgrow it, and the new leaves 

 soon replace the injured foliage. We have found flowers 

 of sulphur efficacious in preventing the spreading of the 

 spot on the foliage.
