66 DENDROBIUM. 



one should be placed upside downi over the 

 hole in the inside, then adding rough broken 

 potsherds in the ca\'ity between the two pots 

 until the larger one is half filled, it will be com- 

 plete with a thin layer of long sphagnum over 

 the whole, to keep the mould from mixing with 

 the drainage ; and finally, the plant should be 

 potted in a mixture of turfy peat, sphagnum, and 

 small potsherds; the first two being well chopped 

 before using. If the plants are large, I pot them 

 three inches above the rim of the pot ; they w^ll 

 then require some thin pieces of turfy peat placed 

 round the outside, and pegged down, to keep the 

 mould from falling off by watering. I then cover 

 the whole with fresh sphagnum, which not only 

 gives it a neater appearance, but retains moisture 

 about the roots much longer. The best time for 

 such operations is when the plants begin to make 

 their fresh growth, for if delayed longer their 

 roots are in danger of being broken, and a sudden 

 check would then be given to the plant. 



Water will be but little required for the first two 

 or three weeks ; by that time they will be well 

 established with roots, and consequently require 

 watering about twice a week ; I also syringe them 

 night and day with a fine syringe during growing, 

 or at least until they have three parts made their 

 growth. I then begin to reduce watering to only 

 once a week, and entirely give over syringing.
