THE ORCHID 



end of the Odontoglossum house, which is 

 a suitable place during the hot months. Cool 

 house Orchids, which are very soon injured 

 by heat, must now be kept as cool as possible. 

 The temperature should be kept down during 

 hot weather by heavy shading and the 

 thorough damping down of every available 

 space several times a day. 



Cymbidium eburneum, C. Lowianum, 

 C. grandiflorum (Hookerianum), C. Tracy- 

 anum and C. giganteum, also their varieties 

 and hybrids, which have passed out of flower 

 and are on the point of making new roots 

 from their young growth are in a desirable 

 condition for being re-potted. The compost 

 I recommend is equal parts fibrous peat and 

 loam, with a fair quantity of sphagnum moss 

 and coarse silver sand. It should be used 

 rather rough, and the plants should be potted 

 moderately firm and much the same as 

 ordinary plants. After re-potting special 

 care must be given in applying water, as over- 

 watering at this stage means absolute ruin ; 

 one good watering after the plant has been 

 re-potted will suffice for a considerable time. 

 Cymbidiums will thrive in a cool part of the 

 intermediate house ; they must be shaded 

 from direct sunshine. The same compost 

 will answer the requirements of any Phaius 

 that require attention. These succeed m a 

 warm, moist, shady corner of the Cattleya 

 house, and when the pots are full of roots 

 abundance of water must be given. A little 

 liquid manure may occasionally be used. 



Anguloas which have passed out of flower 

 may also be re-potted, using the compost 

 recommended for the green-leaved Cypri- 

 pediums. The same remarks apply also to 

 Lycastes ; they both thrive in a shady place 

 in the cool intermediate house. 



Sobralias that are showing their flower 

 spikes, especially if at all pot bound, will 

 benefit by an occasional watering with weak 

 liquid manure water ; this will greatly assist 

 them in developing their flowers. Manure 

 water is beneficial to all terrestrial Orchids 

 when in full growth, or when pushing up 

 flower spikes, but it should never be used in 

 an over strong state. 



Stanhopeas, if they require it, may now

be placed in larger baskets. These should 

 be shallow ones, and instead of crocks I 

 prefer a layer of fern rhizome placed at the 

 bottom in such a manner that the flower 

 spikes can easily push through. A suitable 

 compost is equal parts peat, osmunda fibre, 

 and sphagnum moss- This mixture should 

 be made moderately firm, and water should 

 be applied with caution until the new growth 

 is well advanced. Stanhopeas succeed in a 

 shady position suspended from the roof of 

 the warm house ; they should be frequently 

 sprayed overhead and under their leaves to 

 prevent the attacks of red spider. 



Coelogyne pandurata. With many this 

 Orchid often fails to grow satisfactorily. It 

 requires plenty of heat and a shady position 

 in the warmest house, and when a suitable 

 position has been found for it, it is a most 

 vigorous grower. The compost given last 

 month for Coelogyne cristata will answer its 

 requirements, and the best time to do any 

 re-potting is after its flowers have faded. 

 Coelogynes at all times resent being disturbed 

 at the roots, therefore this operation should 

 be done with care, giving ample room for 

 the plants to develop. The back pseudo- 

 bulbs should be removed to two or three 

 behind each lead, so that the plants may be 

 placed in moderate size pans. C. Dayana 

 and C. asperata will succeed under the same 

 treatment. These plants when in full growth 

 require an abundant supply of water and 

 comprise some of the most thirsty Orchids in 

 cultivation. 



General remarks. In case insects should 

 make an appearance just while the plants are 

 making new growth fumigate at once, for 

 these, if allowed to gain a foothold at this 

 season, are difficult to eradicate. Cleanliness 

 is one of the greatest aids to successful 

 cultivation. The potting of the different 

 plants will occupy the whole of our time and 

 attention, and the sooner it is done the better. 

 Keep the atmosphere of the houses sweet by 

 the admission of air on all favourable 

 occasions, as the health of our plants depends 

 on their needs being satisfied, and a supply 

 of fresh air is as essential as a supply of 

 water.
