The Phalaenopsis thrives best with a minimum night temperature of 16 ° C and a maximum daily 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 aimed at the (north) east or (south) west is ideal. When leaves turn yellow, this can be a sign of an excess of direct sunlight. The failure of flower buds or dark green leaves indicate a possible lack of light.
Do not pour the water for the orchid in the heart of the plant but on the soil in the pot. The ideal irrigation water is lukewarm with an acidity (pH) of 6-7. Rainwater is better than tap water with (too) much lime in it. Preferably give water early in the day. It is even better to immerse the pot in a bucket for one minute. Then the orchid can rest for seven days without water.
In its natural environment the Phalaenopsis has a high humidity. If you want to grow or multiply the plant, then it works best in humid places such as a kitchen, bathroom or conservatory.
It is important that the Phalaenopsis is in an airy soil that provides a moisture-containing drainage. Special orchid soil, which is for sale at most garden centers, is ideal for that. Do not use ordinary potting soil. Because there is often little food in the airy orchid soil, it is best to fertilize the Phaelenopsis through the irrigation water. Special orchid fertilizer is for sale for this. Fertilization is needed in the months of March through October, about twice a month.
When a Phalaenopsis has finished, you can try to get it back in bloom. For this it is necessary to cut off the branch above the second 'eye'. This involves thickening on the branch. You must start counting from below.
If the Phalaenopsis develops aerial roots that grow outside the pot, then this is a sign that the orchid is having a good time. Let the carrots just sit. You do not have to put them back in the pot with the danger of damaging the roots.
The Phalaenopsis has one branch that turns upwards in circles.
