Improper Light Levels
The right amount of light is essential for maintaining plant growth and encouraging re-flowering of your orchid.
High light levels lead to leaves that are yellowish in color and in some cases can cause scorching of the leaves. This scorching first appears as white patches on uppermost leaves, which eventually turn brown. Extreme cases of scorching can kill the plant! Yellowish leaves caused by high light levels are easily remedied by moving the plant to a slightly shadier spot.
Low light levels typically won’t kill your plant, but it is the most common reason people fail to re-bloom their orchids. In this scenario, plant leaves are typically dark green and the plant fails to re-flower during its normal blooming season. The ideal leaf color should be an even, medium-green. Slowly increase the light level over a couple months by introducing the plant to slightly brighter conditions, until the desired leaf color is recognized. In Phalaenopsis, low light levels can also lead to soft, floppy elongated leaves.
Most orchid problems are preventable.
There really is no magic to growing orchids successfully; just some preparation and care is all you need.
