How to Care for a Phalaenopsis Orchid

Orchid Care

The Phalaenopsis Orchid or Moth Orchid is a classically elegant flowering houseplant. Its moth-shaped flowers come in a wide range of colours, and with the right care, they can last from one to two months.

Here’s how to care for your Phalaenopsis Orchid.

Orchid Care


Place your Phalaenopsis Orchid in a warm, bright area preferably near a sunny window. Do not expose to direct sunlight, which can burn the plant.


Do a moisture check by dipping your finger into the potting medium; if the potting medium feels slightly dry, it’s time to water. Soak the potting medium thoroughly, and allow the water to drain. Remove any excess water from the saucer as sitting in it can cause root rot. It’s best to water your Orchid in the morning to allow any excess water to fully evaporate before the night time. Allow the potting medium to slightly dry out before watering again.

Temperature & Humidity

The Phalaenopsis Orchid prefers warm temperatures and high humidity. Mist your Orchid regularly, especially if the air in your home or office is particularly dry.

Like all living, breathing things, fresh is best, so don’t put your plant under an air conditioner where gusts of hot or cold air can harm it.


Keep your Orchid looking lush and fresh by gently wiping the broad leaves down with a moist cloth. Also, remove any faded leaves, roots and flowers.

After the flowers fade, cut the stem about 2-3 cm just above one of its nodes to encourage the plant to re-bloom. If the flower stem has faded as well, you will need to cut it to the base and allow your Orchid to go into a period of rest, which lasts for a few months. Your plant may appear dead, but it’s storing its energy for the next flowering period. Move your plant to a cool area, but still receiving bright indirect light. Water when the potting medium is dry, and fertilise once a month with a liquid fertiliser diluted to half strength. Skip watering during the weeks you use the fertiliser. This process requires patience, but your Orchid will reward you with new flowers for your efforts.
