Learning how to care for orchids comes down to three things: bright indirect light, water only when the roots and bark have dried out, and a chunky bark-based potting mix instead of ordinary soil. Get those right and a common Phalaenopsis (moth orchid) will bloom for two to three months and often flower again the following year.
Most orchids die from kindness, not neglect: too much water, a pot with no airflow, or compact soil around the roots. This guide covers the routine that works for the orchids sold in supermarkets and garden centers, and how to fix problems when they show up.
Quick Answer: Orchid Care at a Glance
- Light: bright, indirect light; an east-facing window is ideal.
- Water: about once a week in most homes, only when the potting mix is dry.
- Temperature: roughly 65 to 80°F (18 to 27°C), with a cooler night to trigger flowers.
- Humidity: 40 to 70 percent suits most houseplant orchids.
- Potting mix: orchid bark, not regular potting soil, repotted every one to two years.
- Feeding: a diluted orchid fertilizer every two weeks while growing.
How to Care for Orchids: The Right Light
Phalaenopsis grow on tree branches in the wild, under a canopy that filters the sun. Indoors, a spot near an east window gives gentle morning light. A south or west window works if a sheer curtain softens the afternoon sun.
Check the leaves for clues. Healthy leaves are medium green. Dark, deep green leaves usually mean too little light and no flowers, while yellowish or bleached patches mean sunburn.
Watering Orchids Without Rotting the Roots
The roots tell you when to water. Most orchids are sold in clear plastic pots so you can see them: silvery-gray roots need water, plump green roots are fine.
- Check that the bark feels dry a little below the surface and the roots look silvery.
- Water at the sink with room-temperature water for about a minute, or soak the pot for 10 to 15 minutes.
- Let all the water drain fully; never leave the pot standing in a saucer of water.
- Water in the morning so the crown and leaves dry by evening.
Water that sits in the crown, where the leaves meet, can cause rot. Blot it with a paper towel if it pools.
Temperature, Humidity and Feeding
Moth orchids are comfortable at normal room temperature. To start a new flower spike, they need a drop of about 10°F (5 to 6°C) at night for a few weeks in autumn, which a spot near a cooler window usually provides. Keep them away from heaters, air conditioners and drafts.
For feeding, use a balanced orchid fertilizer at quarter to half the label strength every two weeks while the plant is growing, and water plainly now and then to flush out salts. Stop feeding or reduce it in winter if growth slows.
How to Get Your Orchid to Bloom Again
Once the last flower drops, look at the flower spike. If it is still green, cut it about an inch above the second or third node (the small bump) counting from the bottom; a new branch often grows from there. If it turns brown or yellow, cut it back to near the base.
- Keep the plant in good light and keep watering as normal after flowering.
- Feed regularly through spring and summer while new leaves and roots grow.
- In early autumn, give nights of 60 to 65°F (15 to 18°C) for several weeks.
- Watch for a new spike, which looks like a green, mitten-shaped tip, and stake it gently once it grows.
Expect reblooming within six to twelve months. A healthy plant with several good leaves and green roots is far more likely to flower.
When and How to Repot an Orchid
Repot every one to two years, once flowering has finished, because bark breaks down and holds too much water. Use a pot only slightly larger than the root ball with plenty of drainage holes, and fresh orchid bark. Trim only dead, mushy or papery roots with clean scissors, and leave healthy green and silver roots, even those growing above the pot, alone.
Common Orchid Problems and Fixes
| Symptom | Likely cause | What to do |
|---|---|---|
| Wrinkled, limp leaves | Too little water or rotted roots | Check roots; water if dry, repot if mushy |
| Yellow lower leaf | Natural aging, or overwatering | Remove if only one old leaf; otherwise water less |
| Buds dropping | Drafts, sudden change, dry air | Move to a stable spot |
| No flowers | Low light or no cool nights | Brighter spot, cooler nights in autumn |
| White cottony spots | Mealybugs | Dab with rubbing alcohol on a cotton swab |
The ASPCA lists the moth orchid (Phalaenopsis) as non-toxic to cats and dogs, which makes it a safe choice in many homes; you can check any plant on the ASPCA toxic and non-toxic plants list.

Conclusion
Orchid care is simple once you stop treating the plant like a normal houseplant: give it bright indirect light, water only when the roots look silver, keep the bark fresh and give it cooler nights in autumn. With that routine, the same plant can flower for you year after year.
FAQ
How often should I water an orchid?
Usually about once a week, but go by the roots and bark. Water when the mix is dry and roots look silvery-gray, and less often in winter.
Do ice cubes work for watering orchids?
Some growers use them, but a thorough watering at the sink is more reliable and gives the roots an even soak. Cold shocks are best avoided.
Why are my orchid’s leaves turning yellow?
One yellow bottom leaf is normal aging. Several yellow leaves usually point to overwatering and root rot, or to sunburn if the patches face the window.
Should I cut the flower spike after blooming?
If the spike is still green, trim it above a node to try for new blooms. If it has turned brown, cut it back near the base.
Can orchids live in regular potting soil?
No. Their roots need air and fast drainage, so use orchid bark or a mix made for orchids instead of standard soil.
