Plant care

Phalaenopsis orchids are surprisingly easy to care for, offering long-lasting blooms that can endure for weeks or even months. With proper watering, adequate lighting, and a bit of attention to their needs, these orchids thrive indoors with minimal effort.

Light

Prefers bright indirect light. Direct sunlight for extended periods can cause leaf burn, while too little light may prevent blooming.

Soil

Thrives in a well-draining mix, such as orchid bark, perlite, sphagnum moss, or coco coir, mimicking its natural environment and ensuring airflow around the roots. Standard potting soil is unsuitable.

Water

Water when the top of the soil is dry. Water thoroughly to ensure moisture reaches the roots but avoid letting water collect in the crown, as this can lead to root rot.

Humidity

Thrives in moderate to high humidity, ideally around 50%-70% or higher. If the air is too dry, consider using a humidifier to keep the humidity high.

Temperature

Best kept in a warm environment, ideally between 18-27°C (65-80°F) during the day and at least 15°C (59°F) at night. Temperature drops can encourage blooming.

Pruning

Use clean, sharp scissors or pruning shears to trim yellowing leaves or dry roots. Encourage new flower growth by cutting the spent flower spikes just above the second or third node.

Fertilizer

Feed it with a balanced fertilizer every 2-4 weeks during spring, summer and autumn. Reduce feeding during winter as the plant's growth naturally slows.

Propagation

Primarily propagated by keikis, which are baby plants that form on the flower spike. Once they develop roots, they can be removed and planted separately.

Common pests

Watch for pests like spider mites, scale insects, and mealybugs. Signs include webbing, sticky residue, or discolored spots, which can be treated with neem oil or insecticidal soap, covering both sides of the leaves.

Troubleshoot

Yellowing leaves may indicate overwatering or poor drainage, while brown edges often signal underwatering. Lack of flowering is often due to insufficient light or lack of a temperature drop at night.

More information

Due to their beauty and extended blooming period, Phalaenopsis orchids have become favorites among plant enthusiasts of all experience levels. These remarkable epiphytes have unique characteristics and adaptations that set them apart from typical houseplants.

Why do roots grow above the pot?

Those silvery roots growing out of your orchid pot are aerial roots, designed to absorb moisture and nutrients from the air. In their natural habitat, Phalaenopsis orchids grow attached to trees, using these exposed roots to collect rainwater and humidity. The silver coating, called velamen, acts like a sponge that absorbs water and turns green when wet.

Can my orchid rebloom?

Absolutely. The secret to reblooming Phalaenopsis orchids lies in temperature variation. After the last flower fades, expose the plant to cooler night temperatures , around 13-18ºC (55-65°F) for several weeks. This temperature drop triggers the development of a new flower spike.

What's inside its thick leaves?

The thick leaves of Phalaenopsis orchids serve as water storage. Unlike typical plants that store water in roots or stems, orchids evolved these succulent-like leaves to survive during dry periods in their native habitats.

Inside, specialized cells hold water for weeks between waterings. This explains why healthy orchid leaves feel firm to the touch, while dehydrated ones become limp and wrinkled.
