Light canvas or scrim shading fixed to roller blinds 
answers the purpose well, but care should be taken not to 
employ heavy, closely woven canvas. Too great attention 
cannot be paid to the working of these blinds, for they 
must never be down except when required for protection

dull intervals. 
The blinds are useful also during severe winters as a 
protection against excessive cold at nights, and in this 
particular the lath roller blinds are the best, and may be 
left in position where they are likely to be required for this 
purpose. 
When canvas blinds are used during the summer and 
removed in late autumn, care should be taken to have 
them perfectly dry before they are stored for the winter 
in some dry place, or they will be useless when they are 
required for placing in position the following spring. 
CHAPTER V 
THE POTTING AND BASKETING PROCESS 
WE are often asked what season is the best for potting and 
basketing Orchids. Experienced growers say that, with the 
exception of the winter season, they are engaged in potting 
operations all the year round, potting each section as it re- 
quires it. Springtime is a period when a general overhaul 
of the plants is usual, and, at that time, plants requiring 
it should be repotted, but those which are not in the proper
