Moth Orchids & Cultural Information
Moth orchid (Genus Phalaenopsis) belongs to the genus of about 60 species of orchids from the family Orchidaceae. This beautiful flower originates from Southeast Asia and parts of Australia.
They are grown mainly for commercial purposes and are crossed to produce hybrids with beautifully white, purple, and pink flowers. Also, they are very easy to grow and in addition are popular houseplants.
In terms of physical appearance, this species of orchid has a short stem that bears several broad leathery leaves. It also belongs to the epiphytic group, meaning it has thick roots and doesn’t require soil to survive. This is why you can usually buy them loosely rooted in pots filled with wood chips.
The flower spike arises from the base of the plant; a moth orchid usually has several long-lasting flowers. These elegant flowers consist of two lateral petals, a central modified petal, a column containing reproductive structures, and finally three petal-like sepals. The flowers are arranged on arching branches and open successively.
Did you know that a single multi-branching flower spike can have more than 20 flowers? One individual flower can last for weeks. The best thing about the moth orchid is that it is particularly good for beginners.

Conditions Required For Successful Growing Moth Orchids Indoors
Orchid moth flowers can be grown very successfully indoors. The most important thing is to find a balance between humidity, temperature, light, and airflow.
Natural & Artificial Light
This part can be quite inconvenient, namely moth orchids need a lot of light, but they can’t experience absolutely any direct sunlight or the leaves will burn. Also, try to rotate it so that all its growth is not directed to one side only.
Your orchid moth can survive on the east window or on a window with shaded south or west exposure. The most important thing is not to expose it to direct sunlight.
On days when there is a lack of sun, you can use supplemental growing light which you will position about 1 foot from the plant. How to recognize that you take good care of your plant? Simply – the plant will have darker green leaves at the top, and red or dark red lines on the undersides.
Temperature & Humidity
Moth orchids are considered warm houseplants because during the period of active growth they require a temperature between about 75 – 85 degrees Fahrenheit. The good thing is that they can also adapt to a normal house temperature (65 – 70 degrees Fahrenheit). Keep in mind, the higher the temperature – the more humidity your plant will need.
In addition, this type of flower likes a nice contrast between night and day temperatures. Without it, the plants will not bloom well.
Being a monopodial plant, the orchid moth grows from a single stem. Therefore, there are no large pseudobulbs in which it can store excess water. Accordingly, this orchid of the genus Phalaenopsis has less drought tolerance.
During the growing season, water your plant once a week, preferably in the morning. On the other hand, during the flowering season, you can water it once every two weeks.
Like all other species of orchids, this one also needs turbulent airflow to prevent root rot, fungus, and many other diseases. You can even use a ceiling or stationary fan to make sure your plant is getting enough airflow.
As for fertilization when growing moth orchids indoors, it is recommended to fertilize it with a weak orchid fertilizer weekly during the growing season. Then, during the flowering season, feel free to reduce fertilization to once a month. You can also use a blooming fertilizer in September or October to provoke a flower spike.
Your orchids need to be pruned after the blooms have faded, that is, during the dormant period. You will usually do this once a year.
As for the procedure, cut the dead spikes (1/2 inch above a node) and carefully deadhead the plant, removing all faded flowers.
Growing moth orchids indoors was once an elite and more than a costly hobby. However, today, due to increasingly advanced production, this hobby has become affordable for all other gardeners as well.
