With its broad, wing-like petals and delicate blooms that can last for months, this orchid is a favorite among beginners and experienced gardeners alike.

Let’s dive into everything you need to know to care for and nurture these stunning flowers so they thrive and rebloom year after year!

Why Choose a Phalaenopsis Orchid?

Long-Lasting Blooms: Flowers can last for 2–3 months with proper care.

Wide Range of Colors: Available in shades of white, pink, purple, yellow, and even speckled or striped varieties.

Low Maintenance: Compared to other orchids, Phalaenopsis are more forgiving and easier to care for.

Indoor Friendly: Perfect for growing indoors, they adapt well to home environments with just a little attention to light and humidity.

Whether you’re a seasoned orchid lover or a first-time grower, this guide will help you keep your Phalaenopsis healthy and blooming beautifully!

Light Requirements

Bright, Indirect Light: Place your orchid near an east- or west-facing window where it can get plenty of indirect sunlight.

Avoid Direct Sunlight: Direct rays can scorch the leaves, causing sunburn. Use a sheer curtain if needed to filter harsh light.

Signs of Too Much or Too Little Light:

Too Much: Yellow, scorched, or leathery leaves.

Too Little: Dark green, limp leaves, and lack of blooming.

Tip: If natural light is scarce, consider using a grow light to supplement!

Temperature & Humidity

Ideal Daytime Temperatures: 65–80°F (18–27°C)

Nighttime Temperatures: A slight drop to 60–65°F (16–18°C) helps trigger blooming.

Avoid Sudden Temperature Changes: Keep your orchid away from drafts, heaters, or air conditioning vents, as rapid changes can stress the plant.

Humidity Needs:

Phalaenopsis orchids love humidity! Aim for around 50–70% humidity for optimal growth.

Increase Humidity:

Use a humidifier.

Place the orchid pot on a tray filled with pebbles and water (make sure the pot sits above the waterline).

Mist the plant occasionally, but avoid letting water sit in the crown (the base of the leaves) to prevent rot.

Watering Guidelines

Proper watering is crucial for keeping your Phalaenopsis orchid healthy. Too much water can lead to root rot, while too little can cause dehydration.

When to Water: Water when the potting medium is almost dry, typically every 7–10 days, but this varies based on temperature, humidity, and light.

How to Water:

Thoroughly soak the roots under lukewarm water.

Let excess water drain completely — never let the orchid sit in standing water.

If using an orchid pot with drainage holes, you can soak the pot in water for 10–15 minutes before draining.

Tip: You can check moisture by sticking your finger into the potting mix or using a wooden skewer — if it comes out dry, it’s time to water!

Potting Medium & Repotting

Phalaenopsis orchids don’t grow in regular soil. They need a well-draining, airy mix that mimics their natural habitat.

Best Potting Medium:

Orchid bark

Sphagnum moss

Perlite or charcoal (for extra drainage)

When & How to Repot:

Repot every 2–3 years, or when the medium breaks down or the roots outgrow the pot.

Gently remove the orchid from its current pot, being careful not to damage the roots.

Trim off any dead or mushy roots with sterilized scissors.

Place the orchid in a new pot, adding fresh orchid mix around the roots.

Water lightly after repotting, and give the plant time to adjust to its new home.

Tip: Use a clear plastic orchid pot to easily monitor root health and moisture levels!

Fertilizing for Healthy Growth & Blooms

Feed your orchid to keep it thriving!

Growing Season (Spring & Summer): Use a balanced orchid fertilizer (like 20-20-20) diluted to half strength every 2–4 weeks.

Dormant Period (Fall & Winter): Reduce feeding to once a month or stop entirely until new growth appears.

Tip: Orchids appreciate a little extra calcium and magnesium — you can supplement with crushed eggshells or Epsom salt occasionally.

Encouraging Blooms & Orchid Maintenance

Phalaenopsis orchids bloom naturally once a year, but their flowers last for months. After blooming, the plant enters a resting phase to store energy for the next flowering cycle.

After Blooming Care:

If the flower spike is still green, trim it back to the first or second node to encourage a second bloom.

If the spike turns yellow or brown, cut it off at the base — a new spike will grow next season.

Tip: To trigger blooming, expose the orchid to cooler nighttime temperatures (55–60°F) for a few weeks in the fall.

Common Problems & Solutions

Root Rot: Caused by overwatering or poor drainage. Trim damaged roots, repot in fresh orchid mix, and reduce watering.

Crown Rot: Happens when water collects at the base of the leaves. Avoid watering from above, and blot excess moisture with a paper towel.

Pests (Mealybugs, Spider Mites): Wipe leaves with a damp cloth or treat with insecticidal soap.
