Phalaenopsis orchids — those elegant "moth orchids" with graceful arches of blooms — are one of the easiest houseplants to care for, yet they reward you with stunning, long-lasting flowers. Whether you just picked up a double-stem stunner from Irvine Village Flowers or are reviving a gift, these simple tips will help your orchid thrive indoors. With proper care, many rebloom year after year!
1. Light: Bright but Indirect
Phalaenopsis love bright, filtered light — think east- or west-facing windows with sheer curtains, or a shaded south window. Avoid direct midday sun, which can scorch leaves (they'll turn yellow or black). Too little light? Leaves get dark green and blooms may not return.
Pro tip: Healthy leaves are a medium green. If they're reddish-purple, move to more light; if very dark, add brightness.
2. Watering: The #1 Key to Success
Overwatering is the top killer, so let the potting mix (usually bark or moss) dry out almost completely before watering again. Check roots: silvery-green means thirsty; plump and green means wait.
Water thoroughly once a week (or every 5–10 days, depending on your home's humidity and season).
Use room-temperature water; run it through the pot in the sink to flush salts, then drain fully — no soggy saucers!
In bloom or warmer months, they may need slightly more frequent drinks.
3. Temperature & Humidity: Cozy Home Comfort
These orchids match average home temps perfectly:
Daytime: 75–85°F (24–29°C)
Nighttime: Above 60°F (15°C), ideally 65–70°F for best blooming
They appreciate 40–70% humidity (easy with a pebble tray of water under the pot — don't let roots touch water). Dry winter air? Mist leaves occasionally or group with other plants.
4. Fertilizing: Feed Lightly for More Blooms
Use a balanced orchid fertilizer (like 20-20-20) at ¼ strength every 2–4 weeks during active growth (spring/summer). Skip or reduce in winter when not blooming. "Weekly, weakly" is the motto — over-fertilizing causes salt buildup and fewer flowers.
5. After Bloom & Reblooming: Patience Pays Off
When flowers fade, cut the spike just above a node (or all the way at the base if it's brown). New spikes often emerge from old ones!
Repot every 1–2 years after blooming (or when roots overflow or bark breaks down) using fresh orchid mix.
Trim dead roots and remove old media.
Quick Troubleshooting
- Yellow leaves? Usually overwatering or too much sun.
- Wrinkled leaves? Underwatering.
- No rebloom? More light or a slight night drop in temp (10°F cooler) often triggers it.
Your Phalaenopsis can bloom 6–12+ weeks per spike and live for decades with these basics.
