Reasons Why Phalaenopsis Aerial Roots Dry Out and How to Fix It

When caring for Phalaenopsis orchids (moth orchids), nothing is more frustrating than seeing shriveled, dried-up aerial roots! Aerial roots are crucial for Phalaenopsis orchids: they absorb water and nutrients from the air and also stabilize the plant. Today, let's take a closer look at what to do when aerial roots dry out.

First, Find the Cause

Humidity too low: Phalaenopsis orchids prefer a humid atmosphere. Once the air becomes too dry, the moisture inside the aerial roots evaporates quickly. Situations such as turning on the heating in winter in the north or using air conditioning in summer in the south often cause indoor humidity to fall short of the ideal level, leaving the aerial roots suffering.

Improper watering: Either you water too little, leaving the potting medium dry for long periods so the aerial roots get none of the water they need; or you water too much, causing the roots to rot from lack of oxygen, which in turn blocks the transport of water and nutrients, and the aerial roots suffer along with the rest.

Potting medium problems: If the potting medium is not airy enough and holds water poorly, it cannot create good growing conditions for the roots. For example, using unsuitable soil, or having aged sphagnum moss or deteriorated bark, will all make the aerial roots feel "uncomfortable."

Solutions

Increase humidity: Place a humidifier next to the Phalaenopsis orchid and adjust the humidity to the suitable 50% - 70% range, so the aerial roots can comfortably take in water. You can also place the pot on a shallow tray filled with water and pebbles, using evaporation to raise the surrounding humidity.

Adjust watering: First check whether the potting medium is dry or moist; when it is dry, water thoroughly. When watering, do not rush; pour slowly to make sure the medium fully absorbs the water. If the roots have rotted because of previous overwatering, take the plant out of the pot, cut off the rotten roots, disinfect with a carbendazim solution, then replace with clean, airy potting medium and replant.

Handling the potting medium: If the potting medium is the problem, by all means replace it decisively! Sphagnum moss should be soaked and then squeezed dry before use, while bark should be clean and of a moderate size. Be careful when changing the potting medium so you do not damage the roots, and after repotting, place the plant in a cool, ventilated spot to recover.

Everyday Prevention

Regular checks: In daily care, pay more attention to how your Phalaenopsis orchid is growing, and check the condition of the aerial roots at least once a week so you can spot and deal with problems in time.

Scientific fertilizing: Regularly apply a dilute orchid-specific fertilizer to boost the orchid's stress resistance and make its root system stronger. But be careful to control the amount of fertilizer to avoid overfertilizing, which can burn the roots.

Dear friends, growing Phalaenopsis orchids is a task that calls for care. As long as you master the methods and deal with problems promptly, you can let the aerial roots of your Phalaenopsis orchid grow strong and thrive, blooming abundantly and filling the pot year after year!
