A CALENDAR OF REMINDERS 213 



and far too little at this season of the year to the cleanliness of the 

 plants themselves. 



Where a gravel or flagged path runs past the cool houses it 

 should be hosed or otherwise damped down in the evening, as this 

 creates a pleasantly moist atmosphere, which, passing through the 

 lower ventilators, benefits Odontoglossums, etc. 



Milton'ta vexillaria should no longer remain in the inter- 

 mediate house, but be given a place in the cool house until growth 

 begins again in the Autumn. 



Importations of Odontoglossums frequently arrive at this 

 season of the year, and a few plants purchased annually give 

 added interest to the collection. 



Any Cattleyas that are sending out new roots and are not 

 coming into flower should be potted. 



Many of the Cymbidiums will require more root-room or 

 new rooting material. 



AUGUST 



Calanthes will be growing freely, and need abundance of 

 water. A little weak liquid cow manure, given once or twice a 

 week to healthy, vigorous plants, will result in strong flower spikes 

 later on. 



Stanhopeas and allied Orchids usually make new growth 

 soon after or while flowering, and should receive prompt attention. 



Towards the end of the month the potting of cool Odon- 

 toglossums should be taken in hand, so that the plants may 

 receive the benefit of pleasant Autumn weather, and become 

 established again before Winter.
