Masdevallias are among the most easily accommodated 
of Orchids. Owing to their natural habitat being at so 
high an elevation they require to be grown in a cool, moist atmosphere 
in small pots, with a compost of peat and sphagnum, and a good depth 
of drainage. During the summer they must be kept shaded from the 
sun, and as cool as possible; in winter they require a temperature not 
lower than 50°. Air should be admitted at all times, avoiding cold 
draughts, and they must have plenty of water during the growing period ; 
less when at rest. They should be repotted in February. Thrips and 
red spider often disfigure the leaves, and slugs eat the young leaves and 
flower-stems ; they must be kept under.
