Phalaenopsis (Orchidaceae) is native to Southeast Asia, the Philippines, and northern Australia. The Moth Orchid bears the name because it resembles a moth in flight.
Exotic and beautiful, orchids have thousands of species. They also have many hybrids. Orchids are a favorite with homeowners. They can become an obsession for the serious plant collector.
Furthermore, contrary to popular belief, they’re not difficult to grow.
Light and Temperature
Your plant will need good light levels in the winter to encourage flowering. An east- or west-facing window is a perfect location. In the summertime, you will need to move it to a shadier spot, but away from direct sunlight.
When the leaves get dusty, you should wipe the dust off with a damp cloth. Dust prevents the leaves from receiving a proper amount of light.
Moth orchids will grow best in a warm environment. Temperatures should be in the 60s at night. During the daytime, temperatures should range from the high 60s to the mid-’80s.
You should always place them in an area away from drafts.
If you have a large, healthy plant but it is not producing flowers, reduce the temperature by 8-10 degrees. Do this for a month. This should result in the development of a flower spike.
Moth Orchids: You WILL Be Successful With These!
Phalaenopsis orchids, or moth orchids, are an excellent choice for the beginning orchid grower. They have a months-long bloom period. They are also easy to care for.
Due to increased commercial propagation, they are one of the most affordable orchids available. These orchids are also one of the few that will rebloom under household conditions.
There are more than 25,000 different kinds of orchids on the planet. The Moth Orchid is the most common type.
Most orchids sold at Crazy Critters are grown in clear pots. This allows you to see what is happening with the roots. It helps in an effort to avoid root rot, which will kill the plant.
Phalaenopsis Culture
Place moth orchids in an east-facing window, out of direct sun. Night temperatures should not dip below 62 degrees Fahrenheit, and daytime temperatures should range from 70 to 80 degrees. The plants can be summered outdoors in a shaded spot.
Water them weekly, in the morning, using rainwater or distilled water. Don’t let the plant sit in water. Give extra humidity by placing it on a saucer full of stones or gravel.
Remove dead plant material promptly, and inspect plants regularly for pests, particularly on the undersides of leaves
How to Identify a Phalaenopsis Orchid
Before you do anything, decide if your plant is a moth orchid. Different types of orchids need different care.
Moth orchids usually have three to six very broad, floppy leaves, and the flower spike appears between those leaves. The flowers can look different and can be pink, yellow, white, or they can have stripes or a splotchy effect.
They are usually about two to four inches wide. They will bloom on a spike that could range from a foot to 18 inches long.
A large plant has more than one spike. It has up to 15 flowers or more. There are a lot of images on the internet that you use for comparison.
First, ensure your plant is a moth orchid. Then, you can safely follow the tips I have presented here for you.
Flowering Moth Orchids
Your blooms should last about three months. Sometimes they can last even longer. They can bloom all through the year.
When the flowers fade, cut the flowering stalk back just above the second node. This node should be visible beneath the spent blooms.
Once you cut them back, a new flowering side shoot will develop.
Watering
Your plant will need to be watered regularly (about once a week) during the growing season. During the winter, you can reduce the watering slightly. Always make sure you have proper drainage.
The foliage needs to be kept dry. When you are watering the plant, be careful not to get the water on the leaves. In the summertime, you can lightly mist your plant.
Over-watering will kill this gorgeous plant. Under-watering it is much less to have detrimental results.
Using Fertilizer
Feed your plant about once a month with a 10/10/10 or 20/20/20 plant food formula. Feeding can be done more often in the growing season.
It is important to ensure that harmful accumulations of salts are leached from the compost. About every fourth watering, use only plain water with no fertilizer.
During the winter months, you only need to feed your plant very sparingly.
Orchid Repotting
Most orchids need to be repotted every few years, and many can be divided into smaller plants. Orchids typically prefer at least partial shade or filtered sunlight and should be protected from cold temperatures.
Common ingredients in commercially available orchid mixes include chopped tree fern fiber. They also include chopped fir tree bark. Other ingredients are osmunda fiber, charcoal, and volcanic rock.
These materials all help to create the loose, well-drained environment that orchids crave.
Choose from containers made of plastic, clay, wire, or redwood. Some orchids can be mounted on a piece of cork or other bark. Every two years or so, you’ll need to replace the orchid growing media for each of your plants.

The Perfect Solution For Healthy Plants

Aphids
Aphids are a common Phalaenopsis pest.
Aphids are soft-bodied, pear-shaped insects about 1/8th-inch long. These green or black bugs suck plant juices. They excrete a sticky sap that grows sooty mold if not detected early.
Dispatch them by squirting the plant all over with a strong stream of water from a spray bottle.
Repeat every few days. For a serious infestation, spray with insecticidal soap according to label directions.
Spray again each week for two weeks following the initial spraying to eliminate successive generations.
Scale
Soft scale is cottony white. Hard scale is round and appears as brown bumps on stems and leaves. Both types are known to attack Phalaenopsis orchids. Under the protective covering is tiny, sucking insects.
Use a cotton swab dipped in rubbing alcohol to dislodge the scale. Alternatively, rub with your fingers or a soft toothbrush. You can use the toothbrush with or without alcohol.
Repeat treatment to kill recently hatched insects. For a serious infestation, spray the plant with neem oil, which will smother the insects.
Mealybugs
Mealybugs are about 1/8th-inch long, oval white insects with filaments on their bodies that give the impression of legs. They hatch and hide in potting media and will lodge in crevices and under pot trays, not just on plants. Mealybugs are about 1/8th-inch long, oval white insects with filaments on their bodies that give the impression of legs. They hatch and hide in potting media and will
Use a cotton swab dipped in rubbing alcohol to dispatch mealybugs. Alternatively, spray the entire plant with rubbing alcohol. Let the alcohol dribble into the base and into the planting medium.
Let stand five minutes, then spray with water. Neem oil and insecticidal soaps also kill mealybugs.
Spider Mites
Spider mites are tiny pests that often are not detected until the result of their damage appears. Leaves look silvery or stippled because the mites have killed the cells of the surface layer by sucking. They also spin webs among leaves.
If you suspect mites, wipe a white cloth over both sides of a leaf. If mites are present, red or brown streaks will dirty the cloth.
Remove mealybugs with a cotton swab dipped in rubbing alcohol. Alternatively, spray the entire plant with rubbing alcohol. Allow it to dribble into the base and the planting medium.
Here’s a list from the American Orchid Society that gives a general outline of growing requirements for orchids that do well outside in Florida:
* Cattleya Alliance Hybrid is the showy corsage variety, especially Laelia anceps, and requires half sun. It’s temperature-tolerant.
* Dendrobiums: The Indian and Australian types are best, requiring half sun. They are temperature tolerant.
* Phalaenopsis is great for beginners and does well in full shade.
* Vanda flowers in summer months and takes a lot of suns.
* Epidendrums, especially the brilliant reed-stem types, do fine in South Florida. They need almost full sun but are temperature tolerant.
*Oncidiums: Choose the Mexican species, or higher-elevation types, with light requirements of bright shade to half sun.
* Paphiopedilums are slippered orchids and fare best in shaded gardens.
* Spathoglottis have broad, palm-like leaves and spikes of purple and yellow flowers. Grow them in shade to half sun.
