While the orchid is suspended above the water

This is invariably a balancing act because orchids also like air movement but constant movement of dry air will dry out the plants. Orchids also like to be gathered close together as this also helps to raise the humidity among the plants. In this way the orchid benefits from the evaporation of the water. Commercial trays are available or a tray can be created from a cake pan filled with stones or inverted pot saucers, anything to allow the orchid pot to be above a pool of water. I would recommend staying orchid flower delivery away from fertilizing altogether while the plant is suspended above the water. During winter months you can reduce liquid fertilizer applications to once a month. During blooming season you might consider a blooming plant formula with elevated phosphorus levels. For convenience, a slow release fertilizer with equal proportions of N-P-K used as directed, can work very well.
