Phalaenopsis orchids, often called moth orchids, are among the most rewarding houseplants you can grow. With the right care, they’ll bloom for months at a time and continue to flower year after year. The secret? Understanding what makes them feel at home.
Light: Finding the Perfect Brightness
Light is one of the most important - and most misunderstood - aspects of Phalaenopsis care.
These orchids thrive in bright but indirect light. Too little light and they’ll refuse to bloom; too much light and their leaves may scorch.
Here’s how to get it right:
Ideal Locations
- Near an east-facing window (gentle morning sun is perfect)
- A few feet back from a south or west window
- Behind a sheer curtain that diffuses harsh light
Signs Your Orchid Is Happy
- Leaves are a healthy medium green
- New leaves grow consistently
- The plant blooms at least once a year
Signs of Lighting Problems
- Dark, floppy leaves → Too little light
- Reddish, yellowing, or leathery leaves → Too much light
Phalaenopsis orchids don’t need intense sunlight - just a bright spot where the sun never hits them directly for long. Think “bright shade,” like the light filtering through tree branches in their natural habitat.
Understanding Your Orchid’s Environment
Phalaenopsis orchids thrive on consistency. Sudden changes in temperature, light, or humidity can stress them and impact flowering.
These orchids prefer:
- Bright, indirect light (direct sun can scorch their leaves)
- Good air circulation
- Moderate humidity
If you’ve found a spot where your orchid is producing healthy leaves and showing steady growth, don’t move it. That location provides your plant the perfect mix of light, airflow, and moisture in the air. Orchids are creatures of habit, and stability helps them flourish.
Watering & Feeding: Where Most Problems Begin
Once your orchid is comfortable in its environment, watering and feeding become the heart of proper care - and one of the most common sources of trouble for beginners.
The Best Way to Water: The Soaking Method
We’ve found that soaking is one of the most effective and natural-feeling methods for Phalaenopsis orchids:
- Allow the potting mix to mostly dry out.
- Submerge the pot about halfway in water for 3-12 hours.
- Lift the pot out and place it somewhere the water can drain away completely.
Orchids enjoy being thoroughly hydrated, but they hate sitting in water. Wet roots are perfectly fine; waterlogged roots, however, can quickly rot. It’s a delicate balance - orchids are a bit particular, but once you get the rhythm, they’re easy to maintain.
Feeding Your Orchid
Feeding helps your orchid grow strong leaves and produce reliable blooms. A few simple guidelines:
- Use a balanced orchid fertilizer (such as 20-20-20 or a fertilizer specifically labelled for orchids).
- Dilute it to half or quarter strength, as orchids prefer weaker, more frequent feedings.
- Apply fertilizer every 2-4 weeks during active growth.
- Skip or reduce feeding during winter or when the plant is resting.
Remember: weakly, weekly is a classic orchid-care motto - gentle, consistent feeding is far more effective than strong, occasional doses.
A Critical Warning: Avoid the Crown
This point cannot be overstated:
Do not let water sit in the crown - the central area where all the leaves meet.
Water trapped here can cause crown rot, one of the fastest and most devastating diseases orchids face. A seemingly healthy plant can collapse in just a day or two if rot sets in.
If water does splash into the crown:
- Gently blot it out immediately with a tissue or paper towel.
In the wild, many orchids grow sideways or upside down, allowing rainwater to run off naturally. When we grow them upright in pots, water is more likely to pool between the leaves - making good airflow essential. A gentle breeze helps evaporate stray moisture before it becomes a problem.
