To achieve long flowering periods, keep Phalaenopsis orchids at the following temperatures:
· Minimum night-time temperature 16°C
· Ideal daytime temperature 20-22°C
· Maximum daytime temperature of 32°C
The Phalaenopsis orchid doesn’t like direct sunlight, especially in the summer months.
Yellow leaves may be a sign of too much direct sunlight, so put the plant in a different place out of the sun. The dropping of flower buds or leaves could indicate a lack of light.
It is best to water orchids with lukewarm water. Rain water is better than tap water, which can have (too much) lime in it. It's best to water the plants early in the day. Pour the water on the soil next to the leaves. An even better way is to soak the pot for one minute in a bucket so the plant can draw up the water from below. The orchid can then rest seven days without water. If the roots in the pot look grey, the plant needs water. If the roots are green, it has enough water. Make sure no water remains in the decorative pot. The Phalaenopsis doesn't like getting its feet wet!
In its natural environment, the Phalaenopsis enjoys high humidity. So if you'd like to cultivate or multiple the plant, it's best to do this in humid places like kitchens, bathrooms or conservatories. Make sure the plant gets enough light, and don't place it next to a fruit bowl or in a draught.
The best feed that you can buy is special orchid fertiliser. You need to fertilise the plant between March and October, about twice a month.
