The Phalaenopsis Orchid plant should be grown in a light position but out of direct sun light at a temperature in the region of 15º-25ºC (60º-75ºF).  Phalaenopsis plants thrive in a moist atmosphere and this can be achieved by misting with tepid water. It will also be beneficial to stand the plant in a saucer of gravel to which water is added, maintaining the level below the gravel surface to avoid the compost becoming over wet.  If the temperature falls below 18ºC (65ºF) do not mist the plant as this can lead to rotting in the vulnerable leaf joints. Stems that have flowered should be cut back to a lower node to encourage further flowering.

Throughout the year orchids can be fed with a house plant fertilizer, but not more frequently than monthly. It is important to remember that in their natural habitat the orchids would not receive high levels of fertilizer so use low concentrations or you will do more harm than good. 

Phalaenopsis do not require re-potting on a regular basis and every 2-3 years during spring, when not flowering, is adequate. Pre-mixed orchid composts are available from garden centres.
