How to Care for Phalaenopsis Orchids: The Complete Home Guide

Phalaenopsis Orchids or Moth Orchids have a way of making any room feel a little more special. With their graceful stems, long-lasting flowers, and beautiful range of colors, it’s easy to see why they’re one of the most popular orchids to keep at home.

And while they may look delicate, Phals are surprisingly easy to live with once you understand what they need. A little attention to light, water, and their roots can help keep your orchid healthy long after its first blooms have faded.

Here’s a simple guide to Phalaenopsis Orchid care at home and how to encourage your plant to bloom again.

Find the Right Light

Phalaenopsis Orchids love light, but they don’t necessarily want to spend the afternoon sunbathing. Bright, indirect sunlight is usually best.

• Place your orchid near an east- or west-facing window.
• Keep it away from harsh, direct afternoon sunlight.
• Use a sheer curtain if the sun coming through the window is particularly strong.
• Look for firm, medium-green leaves as a general sign of a happy plant.
• Very dark green leaves may mean your orchid needs more light.
• Yellow or scorched patches can indicate too much direct sun.
• Finding the right spot can take a little experimenting, so don’t be afraid to move your orchid if it doesn’t seem happy where it is.

Water When Your Orchid Needs It

When it comes to watering Moth Orchids, more isn’t always better. Overwatering is one of the easiest ways to run into trouble.

Instead of following a strict schedule, check the plant and potting medium before reaching for the watering can.

• Water when the potting medium is beginning to dry.
• Look at the roots if your orchid is in a clear pot. Silvery or pale roots can indicate that it’s ready for water.
• Water thoroughly so the roots and potting medium are evenly moistened.
• Allow excess water to drain completely.
• Never leave the orchid sitting in standing water.
• Avoid using ice cubes as your primary watering method; room-temperature water is a better choice.

Depending on your home, season, and potting medium, your orchid’s watering needs can change. Checking the plant itself is much more useful than relying on the calendar.

Golden Heartstrings 

Keep the Crown Dry

There’s one little spot you’ll want to pay extra attention to when watering: the crown, or the center where the leaves meet.

• Direct water toward the roots and potting medium.
• Avoid pouring water directly over the leaves.
• Don’t allow water to sit between the leaves or in the crown.
• If water collects there, gently blot it away with a clean tissue or cloth.

Keeping the crown dry helps lower the risk of rot and protects the orchid’s growing point.

Let Those Roots Breathe

Those slightly wild-looking orchid roots are part of the plant’s charm. Phalaenopsis orchids naturally appreciate plenty of airflow around their roots, which is why regular potting soil usually isn’t the best choice.

• Use a potting medium made specifically for orchids.
• Orchid bark, sphagnum moss, or a suitable combination can work well.
• Choose a pot with good drainage.
• Avoid packing the potting medium too tightly around the roots.
• Don’t automatically cut off aerial roots growing outside the pot, they’re normal.
• Repot when the potting medium begins to break down or the plant has clearly outgrown its container.
• Healthy orchid roots can look a little unruly, and that’s perfectly fine.

Keep Your Orchid Comfortable

You don’t need to recreate a rainforest in your living room. Phalaenopsis orchids generally do well in comfortable indoor conditions.

For a happy orchid:

• Keep it away from strong heating and air-conditioning vents.
• Avoid cold drafts and sudden temperature changes.
• Provide moderate humidity when possible.
• Allow gentle air circulation around the plant.
• Keep it away from extreme heat or prolonged cold.
• If you’re comfortable in the room, there’s a good chance your Phalaenopsis orchid will be comfortable there too.

Fertilize Without Overdoing It

Fertilizer can support new roots, leaves, and future flowers, but orchids don’t need to be heavily fed.

• Choose a fertilizer formulated for orchids.
• Follow the instructions on the product rather than guessing the amount.
• Fertilize more lightly during periods of active growth.
• Avoid applying an overly concentrated fertilizer.
• If your orchid is new, give it some time to adjust before worrying about feeding it.
• Think of fertilizer as a little extra support rather than the secret to keeping an orchid alive.

Don’t Panic When the Flowers Fall

One of the most common concerns new orchid owners have is seeing those beautiful flowers begin to drop. In most cases, it’s simply the end of the orchid’s natural blooming cycle.

After the blooms fade:

• Continue watering and caring for the plant normally.
• Pay attention to the health of the leaves and roots.
• Check whether the flower spike remains green or begins turning brown.
• Trim spent flower spikes appropriately based on their condition.
• Continue providing bright, indirect light.
• Be patient while the plant focuses on roots and leaves.
• An orchid without flowers is still very much an orchid worth caring for.

Encourage Your Phalaenopsis Orchid to Rebloom

Yes, your Phalaenopsis orchid can bloom again. It may simply need a little time to recharge.

To encourage Phalaenopsis orchid reblooming:

• Continue providing plenty of bright, indirect light.
• Maintain a consistent watering routine based on the plant’s needs.
• Keep the roots healthy and well drained.
• Continue light feeding when appropriate.
• A modest difference between daytime and nighttime temperatures can help encourage a new flower spike.
• Watch for new roots and leaves, which are encouraging signs of healthy growth.
• Give it time, reblooming doesn’t happen overnight.
• Spotting a fresh flower spike after months of care is part of what makes growing orchids so rewarding.
