FEBRUARY, I910.] THE ORCHID REVIEW. 43 
CALENDAR OF OPERATIONS FOR FEBRUARY. 
By W. C. Price, Oakdene, West Didsbury. 
CyPRIPEDIUMS.—Many of these will now have finished flowering, notably 
C. insigne, C. X Leeanum, and the hybrids of this group, and any that 
require potting should be attended to at once, as advised last month. If a 
plant is in need of fresh compost, I believe in repotting it. Toupdressing I 
have never liked. I think it is very misleading to put a layer of new 
material on the top, leaving the older compost, which must be partly 
decayed, underneath, for you cannot see b-low the surface, and therefore 
are guided by it, while the roots may be perishing below, and the plant 
depending only upon the roots in the new material, which is not at all 
satisfactory. If repotted you know the condition right to the bottom. C. 
xX Euryades, X Lathamianum, xX Calypso, x nitens, x Hindeanum, 
Boxalliand its hybrids, also C. X aureum and its varieties, Surprise, C2dippe, 
Cyrus, virginale, magnificum, &c., will be in full flower this month, and 
many others, too numerous to mention, will make a good show in conjunction 
with the Dendrobiums. 
CyMBIDIUMS.—Cymbidium Tracyanum will now be pushing up its 
young growths, and any that want repotting should be attended to at once. 
Use a compost of good loam two-thirds and one-third peat; place two or 
three clean crocks for drainage, and work the compost between the roots 
carefully to avoid breaking them; pot firmly, and they will require very 
little water till well rooted. These plants do not like disturbing, and if a 
plant has room enough to make its new bulbs comfortably, it is better to 
leave it as it is, and give it alternate waterings with weak liquid cow 
manure during the growing season. Do not use larger pots than necessary, 
as they flower much better when the pots are filled with roots. C. 
Lowianum, eburneum, and x eburneo-Lowianum are now pushing up their 
spikes, and will require copious supplies of water till they have finished 
flowering, when they will rest for a short time. They can:then be treated 
the same as recommended for C. Tracyanum. They should be examined 
frequently for red spider and small brown scale, which are very partial to 
Cymbidiums. These can easilybe got rid of if taken in time, by sponging 
the leaves and bulbs with a diluted solution of insecticide. A temperature 
of 55° to 60° suits them admirably, and a light position, but they do not like 
it too bright. 
MILTONIAS.—Miltonia vexillaria and its varieties Leopoldi and rubens, 
with M. X Bleuana, will be best in the Intermediate house till the end of 
April, when they can be moved into the Odontoglossum house. Th 
require a warmer temperature during the winter months, while they are 
making their new growths, and the young leaves are not so apt to stick
