Compost should be straight brown osmunda fiber. The 
Cypripediums should be repotted every two years right after flow- 
ering. 
ONCIDIUM 
(Intermediate) 
Compost—coarse ormunda fiber with ample drainage. 
When in active growth an abundance of water and light is beneficial. 
After growths have matured, water should be retarded until flowering 
spikes appear. (Note: Oncidium splendidum should be dipped 
weekly after growth is two inches high. After flowering they should 
be severely dried off and only syringed, or premature and weak 
growths result.) Many of this species do well suspended from the 
roof. 
PHALAENOPSIS 
(Warm) 
Compost should be brown osmunda fiber in special bas- 
kets, or pots with numerous holes in the sides and bottom, and a 
large amount of broken crock, so as to allow ample drainage. Never 
allow the plants to dry out. Repot as often as the compost becomes 
soft or stale, and allow the roots to protrude. During active growth 
they want a liberal supply of water and careful early morning 
spraying, with the atmosphere always moist, and enough air so 
that the same does not become musty. The plants require much 
light but cannot stand the direct rays of the sun. North and east 
exposure is recommended. The plants should be hung, or placed 
on the top of a high bench. 
DISEASES AND INSECTS 
WET-ROT is brought on by an over-moist or stagnant 
atmosphere, and is usually detected by a semi-transparent appear- 
ance of the parts affected, which soon become dark brown. If 
noticed at the commencement, it can be readily checked by slitting 
the outer skin with a sharp knife, and removing the plant to a more 
airy position for a few days. 
DRY-ROT is caused by a fungus which attacks the rhizome 
of the plant. It is often produced by burying the rhizome, or base 
of the plant, in the compost. Cypripediums are susceptible to it. 
Large healthy growths, when attacked, show a sickly pale color 
in the foliage. On examination of the base, it is found discolored 
or of light brown appearance. If the affected portion is quickly 
removed with a sharp knife, it will usually give no further trouble; 
otherwise, it will spread and destroy the plant.
