THE ORCHID REVIEW. 171 
CALENDAR OF OPERATIONS FOR JUNE. 
By H. A. BURBERRY, Orchid Specialist, King’s Heath, Birmingham. 
For the summer temperatures and general management of the various 
departments see last month’s Calendar. 
Vanda teres and V. Hookeriana are now making a fine show. These 
lovely species prefer a hot, sunny part of the warmest house, and should be 
syringed several times daily with tepid soft water. They are best grown 
when fixed on a moss-clad, teak wood raft, or cylinder, of good length, 
allowing for the tall growth, which is very rapid and vigorous under good 
cultivation. When they have become too leggy, as they do in course of 
time, they should be lowered by cutting the receptacles in half, and bringing 
the top part down to the base. Rarely do these species flower successfully 
unless treated to the full sunshine and syringed liberally, and even then 
some plants are more shy than others. 
Vanda suavis, V. tricolor, and V. insignis, on the other hand, prefer the 
ordinary shady conditions which most other Orchids enjoy. In fact I may 
say the majority of the species of this genus in cultivation enjoy an abun- 
dance of shade and moisture, especially during the summer, which is their 
growing season, and that they are not over partial to great heat, but will 
_ $row even better in the Cattleya house than elsewhere. The large-growing 
kinds with their handsome foliage look well on the stages, whilst other 
smaller kinds, such as V. ccerulea, V. ccerulescens, V. Denisoniana, V. 
Kimballiana, and V. Roxburghii, are better if suspended in baskets or 
cylinders. They should be fixed in their receptacles firmly, with crocks 
and charcoal, and surfaced over with fresh sphagnum moss, which should 
have enough water to cause it to grow freely during the summer. 
Dendrobiums of the thyrsiflorum and densiflorum section will now be 
starting to grow freely, and should be given the warmest house until comple- 
ted, taking them out again to cooler quarters immediately they have finished, 
gradually hardening them so as to withstand the greenhouse temperature 
for the winter. These sturdy and grand old species soon become badly 
spotted, and degenerate never so quickly as when left to rest in heat and 
moisture. 
It will now be the cultivator’s chief pleasure, having most of the 
re-potting done and his plants in their proper growing quarters, to provide 
for them the best possible growing conditions, and note their progress, for 
they wil now advance with rapid strides. It will soon be apparent now how 
the plant which required re-potting, and was done properly and at the 
right time, will come away and pass that one which wanted it as badly but 
did not get it, and the difference will be more marked as the season ad- 
vances. I amno advocate for potting for the sake of potting when it is not
