The Phalaenopsis thrives best with a minimum night temperature of 16 ° C and a maximum day temperature of 32 ° C. An ideal daytime temperature is between 20 and 22 ° C. This orchid requires a lot of light but does not tolerate direct sunlight, certainly not in the summer months. A place on the windowsill focused on the (north) east or (south) west is ideal. When leaves turn yellow, this can be a sign of too much direct sunlight. The failure of flower buds or dark green leaves indicate a possible lack of light.
Water and humidity
Do not pour the water for the orchid in the heart of the plant, but on the earth in the pot. The ideal irrigation water is lukewarm with an acidity (pH) of 6-7. Rainwater is better than tap water that contains (too) much lime. Give water early in the day. It is even better to immerse the pot in a bucket for one minute. The orchid can then safely run without water for seven days.
The Phalaenopsis has a high humidity in its natural environment. Therefore, if you want to grow or propagate the plant, it works best in humid places, such as a kitchen, bathroom or conservatory.
Soil and Fertilization
It is important that the Phalaenopsis is in an airy soil that provides a moisture-containing drainage. Special orchid soil, which is available at most garden centers, is ideal for this. Prefer not to use normal potting soil. Because there is often little food in the airy orchid soil, it is best to fertilize the Phaelenopsis via the irrigation water. Special orchid fertilizer is available for this purpose. Fertilizing is required in the months of March to October, around twice a month.
If a Phalaenopsis has finished flowering you can try to get it back into bloom. For this it is necessary to cut the branch above the second 'eye'. This involves thickening on the branch. You must start counting from the bottom up.
If the Phalaenopsis develops aerial roots that will grow outside the pot, this is a sign that the orchid is having a good time. Just leave the roots. You do not have to put them back in the pot with the risk of damaging the roots.
