years’ growth allowed. When you have knocked the plant from the pot remove all 
decayed compost, disturbing new roots as little as possible. 
A sparing amount of the following mixture sprinkled into the pot, when 
repotting, is beneficial — 1g well-rotted sod, 44 sand, and 44 aged cow manure. 
(A six-inch pot, we have found, requires about a three-inch pot full of this compost.) 
Cymbidiums will be benefited by weak applications — the weaker the better — of 
cow manure every two weeks from June to flowering. 
Water abundantly during the growing season. Retard water from the 
first of August until the first of September, but do not allow the bulbs to shrivel. 
Withholding water seems to retard the new growth and throw the plant into spike. 
Many growers may not concur on this point, but we suggest that you try growing 
some of your Cymbidiums this way. 
Cymbidiums like plenty of air and a damp, moist atmosphere. They 
should be grown as cold as possible, even as low as 45°, as frost will not hurt them 
after the growths have matured. Give the greatest possible amount of light. If 
grown in a small house, they will be benefited if placed out of doors in partial shade 
from June to September. Cymbidiums are in some state of growth during the 
entire year and, like Cypripediums, should be kept actively growing. 
CYPRIPEDIUM 
Cypripediums should be kept moist at all seasons, with the exception of 
the newly repotted plants, which should be kept somewhat on the dry side. They 
should not be dried out between waterings to the extent of the Cattleya genus. 
They require a moist atmosphere, and should be shaded from the direct rays of the 
sun at all times. Extremely weak applications of liquid cow manure are beneficial 
during September and October. 
Compost should be straight brown osmunda fiber. The Cypripediums 
should be repotted every two years right after flowering. 
DENDROBIUM 
With Dendrobiums especially, care should be taken not. to overpot. A 
compost of plain osmunda fiber should be placed in as small a pot as possible, and 
repot only when necessary, when the roots on the new growth are just beginning 
to protrude. 
After the new growths are made up — nobile type — from October to 
November allow the plants to dry off. Keep them on the cool side, even down to 
45°. Syringe occasionally, about twice a week. As the flower buds form move to a 
warmer location and gradually increase water as new growths and root action 
appear. From March to September they should be grown as warm as possible with 
plenty of humidity. 
Dendrobiums require shading of young growths until they are made up, 
but should have plenty of light when they are matured. They do well when sus- 
pended from the roof, thus affording more bench room for other plants.
