Tips for Growing Orchids: The Resting Period
Many orchids require a resting period, usually from late summer to mid autumn. During this time they may lose their leaves so that only the pseudobulbs remain.

When the leaves have fallen, or when the pseudobulbs have grown stout and healthy, move the plant to a shelf in better light and in a cooler part of the greenhouse
. Reduce the humidity to a minimum.
During the resting period, orchids with pseudobulbs need no water unless the compost dries out completely; then drench thoroughly. Orchids without pseudo-bulbs
need occasional watering. When growth begins again, return the plant to its normal place and resume watering.
