Doritaenopsis should be treated as the same.
The ideal temperature range is between 20-27c Night temperature should not fall below 20c except for spike initiation As the temperature increases the humidity must also be increased. This can be done by placing the pot on a layer of gravel in a saucer of water.
A optimum amount of light between 1000-1500 foot candle in the greenhouse or placed near a east facing window in the home During dull winter days a northern light source may be beneficial but do not expose to direct sunlight As a guide if the leaves turn very dark green increase the light, If the leaves start to turn yellow decrease the light.
Unlike many other orchids Phalaenopsis have no bulbs for nutrient storage. Watering should be done when the growing medium (bark) appears to be drying out They should not be over watered as this can cause root rot ensure that the water flows freely from the pot Water around the plant and not in the crown of the plant as this also leads to rot If water gets in the crown remove same with a paper towel or similar.
When the plant is in it’s growing period and flower spikes have been set the use of a balanced 20:20:20; soluble fertilizer at half strength could be used. When initiating the flower spikes a fertilizer higher in phosphorus and potassium is recommended
E.g. 2:10:10. It is advisable to fertilize weakly often so the plant is receiving nutrients in a steady form.
The Phalaenopsis orchid has a few pests that can cause serious damage to the plant and must be controlled. These include mealy bug, scale, and spider mite, Fungal and bacterial infections. Good air movement and a clean environment is vital in avoiding these pests.
