The Phalaenopsis orchids are an exotic flower that is nearly impossible to grow outside. Yet as indoor plants, they brighten up any indoor space. Still, the Phalaenopsis genus provides plant lovers with many popular orchids, especially for the beginner.
Today, we will help you care for the Phalaenopsis spp.
Phalaenopsis Orchid Care
The Phalaenopsis orchids grow in the tropical regions of Australia and Asia. The flower stem grows from the axils developing multiple flower buds. These flowers can bloom for months when you care for them properly.
The flowers are long-lasting and displayed on arching branches. One flower spike can have up to 20 flowers, each lasting for weeks. Still, if you want to grow moth orchids in the Phalaenopsis genus, you can do this outdoors in the USDA hardiness zones 10 to 12.
Anywhere else, it would be best to grow the moth orchid indoors.
How to Grow Moth Orchid Indoors
While the Phalaenopsis orchids are not oversensitive, they can grow well under the right conditions. The best part is they reward you with some showy blooms as if it is blooming plants.
You will see it growing tree trunks with branches in its natural habitat, which best mimics the same conditions as indoor plants.
It helps find the right balance between airflow, light, temperature, and humidity for successful growth. The important thing is to keep checking the overall health of your orchid.
Healthy orchid displays bright green leaves. You may see some yellow leaves at the bottom, but it is not always bad.
For orchids, this is normal as the young leaves become a priority for their health while the bottom leaves die back.
So, let’s dig in and see what your Phalaenopsis orchid needs to flourish and look healthy.
The Type of Soil Phalaenopsis Orchids Needs
Regarding Phalaenopsis orchid care providing the best living environment, it needs suitable soil. In its native habitat, the moth orchids grow on trees and are epiphytic orchids. Hence, it needs a host, and it helps to mimic these living conditions.
So, potted orchids need a potting medium made from redwood bark chips, fir tree bark, or even pine bark chips. Then complete the potting mix with sphagnum moss, coconut husk, perlite, or charcoal to retain moisture.
You can buy orchid mixes if you do not prefer making up your potting medium yourself. The vital thing to having healthy roots is to provide enough air circulation not to suffocate.
Light Requirement for Phalaenopsis Orchid
The Phalaenopsis are low light types of orchid. Exposing them to direct sunlight can scorch those gorgeous light green leaves. Hence, it would be best if you found a balance for your epiphytic, outdoor plants.
The best spot in winter is at the east or south-facing window to receive direct light exposure. Still, please rotate your plant from time to time to provide consistent growth. The best way to know when you grow orchids if the light is too bright or too little is through the leaves.
Many orchids will produce a vibrant light green leaf with the correct lighting. While dark green leaves show, it is receiving too much light. The foliage can get a pink or red tinge along the leaf margins turning yellow.
If you cannot provide the correct natural light, then it helps to use supplemental grow lights. We recommend placing your orchid about 12 inches underneath the growing lights if treated as an indoor plant.
How To Water Phalaenopsis Orchid Plants
The Phalaenopsis is part of the monopodial orchid genus, which grows with a single stem. This elegant plant does not have large pseudobulbs found at the branching. Hence, it does not store a lot of water and is not drought tolerant.
You can water your plant weekly during the growing season or when you notice the exposed roots turning white-silver. The best water is tepid water run over your plant, the bark, and the aerial roots about four times with lapses of ten minutes.
It will help give the plant enough time to absorb the water. Then leave the excess moisture to drain and empty the catch sauces. Neither should water rest around the stem, resulting in leaf and root rot.
The roots will then turn green, showing that it has received their fill of water. When you see flower stalks, you can reduce your watering schedule to every other week. When you do this, you will see the beautiful flowers displayed.
During summer, the growing season, you can provide your orchids with diluted orchid fertilizer every fourth week. Then, during the flowering phase, you can skip feeding from fall and winter to spring.
This is because too much fertilizer results in too much foliage without blooms. In the orchid culture, many people give their plant a bloom booster from September to October. They do this to start the flower spike.
Temperature and Humidity Levels
The beautiful plant is a warm houseplant preferring temperatures between 75°F and 85°F. Yet, the orchid can adapt to your average home temperature. But the higher the temperature your plant needs, the higher humidity with enough airflow to prevent disease.
In the orchid culture, many successful growers have ceiling fans or use a stationary fan where they grow orchids. Another thing about these beautiful flowers is that they need cool nights around 55°F to induce the flower spike to bloom.
Hence these humidity orchids need the correct moisture levels and temperature to flourish.
The best time to repot your orchid is in spring, planted in a free-draining container with enough drainage holes. Some excellent containers are four- to six-inch pots made of plastic or terra cotta.
The reason to repot Phalaenopsis is that it is finished blooming. Alternatively, if the roots grow out of the container, it also helps to provide your orchid with a new home. It can take up to two years before you need to repot orchids.
Another helpful thing is to disinfect the container with a weak bleach solution and wash your hands and tools before repotting. Then fill the pot with some potting mix. Finally, remove our plant to check the roots and remove the brown roots.
Then place your plant into the new pot and moisten it with water. You can then mist your plant daily until new roots start to form. Also, keep your plant in indirect light.
Encouraging Phalaenopsis Orchids to Bloom Again
When orchids in nature grow during the winter, you see the flower stems, and the cold encourages new flower buds to grow. Once your orchids complete flowering and the blooms fall off, you can cut the bare flower stem.
You can cut the node below a previous bloom or branch. If you see a brown or yellow stem, it helps to remove the whole flower spike. Then move your plant to a cooler place, keeping it in bright indirect light to give it rest.
You can then water less and not feed your orchids during this time.
Propagating Your Phalaenopsis Orchids
You can propagate your orchid by seed, yet it is time-consuming and requires special equipment. The easiest method for home growers is planting the Keiki growing on the parent plant. Hence, you get an identical copy of the mother orchid.
When you see the baby forming on the parent plant on the new or old flower spikes, the best is to leave it there for up to a year. Then you can remove it to place it in its pot. Here is the process to help remove and plant the Keiki:
First, sterilize some scissors and the pot you plan to use for your Keiki.
If you see the baby is about three inches long with up to three leaves and a few roots, you can cut it away from the plant. The best is to keep the roots intact.
Prepare your potting mixture and plant the baby in it, exposing some of the top root parts.
Then mist your plant daily until it becomes established and care as usual.
