THE ORCHID REVIEW. 185 
CALENDAR OF OPERATIONS FOR JUNE. 
By H. A. BURBERRY, Orchid Specialist, King’s Heath, Birmingham. 
For the tempertures of the various houses, see last month’s Calendar ; 
also for the general conditions and management of the same. 
REPOTTING.—Do not omit this important work in any instance when 
it appears necessary, and get through with as much of it as is possible 
during the present month, for in no other month during the year will the 
plants so quickly take hold of the new materials. Let it always be the 
rule to keep newly potted plants for a time well shaded, and the surface 
of the compost well moistened with the syringe. Otherwise undue 
shrivelling and loss of foliage may result. In all cases, except where 
otherwise advised, clean, living sphagnum moss and fibrous peat in 
equal proportions, intermixed with a small amount of finely broken 
charcoal and crocks, is the best possible material in which to pot. Well 
drain the pots from half to three quarters full of broken pots, rubble, or 
something of a similar open nature. A liberal quantity of charcoal used 
in the drainage is a good thing, but, if new, it should first be well soaked in 
water and exposed to the weather. I prefer, after placing one large inverted 
piece over the hole at the bottom, for the remainder of the drainage to be 
broken rather small, the top layer being the smallest so that it presents an 
even, level surface. See that the compost comes well up to the base of the 
last formed pseudobulb so that the new roots may instantly enter the same. 
This should be done even at the risk gi burying the bases of a few of the 
older or less important pseudobulbs. 
There are a number of species which I find are generally grown best 
if repotted each year, and in nothing but fresh sphagnum moss intermixed 
with charcoal. They are chiefly Mormodes, Catasetums, and Cycnoches. 
These delight in an exceptionally long and dry rest from autumn until 
spring, or early summer, when they again commence to grow, and should 
be shaken right out, repanned or basketted. They should from this date 
be subjected to the brisk heat of the East Indian House, but much water 
should not be applied until the new growths are nicely advanced, and well 
stocked with new roots, when they should have liberal quantities until — 
their blooming period has passed, and the growth is matured, when the 
resting period again commences. Avoid as much as possible letting the 
water lodge in the young growths, or they may possibly rot off, which 
they are certain to do if any kind of liquid insecticide gets there. 
On the other hand, there are some few species which I find are best 
cultivated in nothing but peat, using no moss whatever. They are as 
follows :—Lezlia crispilabia (Lawrenceana), L. Digbyana, L. glauca, 
Oncidium divaricatum, O. Harrisonianum, O. pulvinatum, and O.
