How to Care for Orchids (2023)

Orchids are popular houseplants that typically can be started anytime for indoor growth, though repotting is best after flowering. Orchid care for beginners is somewhat easy, as long as you understand the plant's ideal conditions and maintenance requirements.

While there are many orchid species to choose from, they all have similar physical characteristics. Orchids are easy to spot because of their tall, gently curving stems (i.e., flower spikes) that are covered with blooms in solid colors or speckles. Their petals and sepals (innermost petals) are typically found in groups of three. Depending on the variety, an orchid's petals can have ruffled or notched edges. Orchid leaves are coated with a heavy waxy film to prevent water loss. Some orchid species grow faster than others, but overall they have a relatively slow growth rate.

Quick Guide to Growing Orchids

Caring for an orchid indoors has some fairly straightforward requirements that even beginners should be able to manage:

  • Use a light, porous growing medium and a pot that allows for good air flow, such as unglazed clay or a specialty orchid pot with built-in spaces.
  • Offer plenty of bright, indirect light.
  • Allow the growing medium to dry out between waterings.
  • Feed with an orchid-specific fertilizer or what is a balanced formula such as 20-20-20 at half strength the concentration recommended. Administer when the plant is actively growing.
  • Cut off the flower spike after it ceases blooming, and repot if the plant is root-bound only after blooming is complete.

Orchid Care

The golden rule fororchid care indoorsis to duplicate the plant's natural conditions as closely as possible. In nature, most orchids are epiphytes, meaning they grow on other objects, clinging to rough bark or even stone. And their roots are water-gathering organs that needfresh airflow to remain healthy.

When you first obtain your orchid, it will likely be healthy and in bloom. However, many store-bought orchids are potted in the wrong conditions for long-term growth. They are usually sitting in plastic containers and packed tightly with moss around the roots, which can result in too much retained moisture and consequently root rot. But even if the container isn't ideal, never repot an orchid while it's in bloom. Instead of repotting, it's better to back off on watering.

Then, orchid care after flowering involves shifting your thinking to long-term maintenance. Most growers snip off the old flower spike near the base. (Some retain the spike hoping for a rebloom, which occasionally does happen.) Also after the orchid blooms fall off, you can repot your plant into a more suitable container with the right growing medium.

Orchids need bright light to produce blooms. However, direct sun can burn them. Opt for bright, indirect light such as that from a south- or east-facing window.


Orchids do not grow in regular potting soil or potting mix. Instead, you ​​can purchase or make your own orchid growing medium, which should be light and fast-draining. Common mixes include bark, sphagnum moss, perlite, and peat. A slightly acidic pH is ideal.


Orchids need to dry out between waterings to prevent rot. One way to tell whether it’s time to water is if the growing medium feels dry to the touch and the pot feels light. Or look at the roots themselves. If they’re plump and white or green, that means they’re well-watered. If they’re shriveled and gray, they need water. And if they’re shriveled but spongey and black or brown, they could be rotting.

You’ll typically need to water twice a week in the warmer months when the plant is actively growing and only once a week in the colder months. Use room-temperature water, and water slowly until it flows out of the pot.

Temperature and Humidity

Depending on how they're classified, orchidsdo best in ranges in between 50 degrees and 90 degrees Fahrenheit. And they prefer humidity levels from around 40% to 70%.

You can keep your orchid blooming longer if you provide a sufficiently warm and somewhat humid environment. Don't place your orchid where it will experience cold drafts or exposure to direct sunlight or heating vents. Dry air, direct heat, and chills are enemies of these delicate flowers.


During the growing season, use an orchid-specific fertilizer, following label instructions. Don't fertilize in the winter.

Types of Orchids

About 30,000 species of orchids live in the wild, along with more than 100,000 registered hybrids. Knowing the orchid variety you have is essential for its care. The majority of commonly available orchids for purchase are one of two varieties:

  • Phalaenopsis (moth orchids): These orchids have round flowers with a pronounced lip that grow on a single tall stalk arising from a whorl of fleshy, oval leaves. Flowers are usually white, purple, pink, or some combination thereof.
  • Dendrobium (cane orchids): These orchids have small flowers that grow in rows on stalks that arise from thick canes, often with several flower clusters per plant. Flowers are typically white or purple. Dendrobium leaves are narrow and emerge from the sides of the cane.


Proper pruning of old wood will make way for new blooms. However, different orchids require different pruning methods. When pruning an orchid, make sure your tool is sharp and sterilized. A clean cut will help to keep an orchid healthy.

In general, remove faded orchid blooms to keep the plant from spending energy on old growth. After flowering is complete, you typically can cut off the flower spike. However, certain orchid varieties are known to rebloom on the same spike. In that case, you can remove the faded blooms but not the spike.

Propagating Orchids

Propagating orchids by seed is notoriously difficult because the minuscule seeds need extremely specific conditions that are hard to duplicate. The most common way to propagate an orchid is by division. If you already have a somewhat mature or large orchid and you'd like to divide it into two stand-alone plants, take these steps:

  1. Moisten the growing medium to make it easier to remove the plant from the container.
  2. Examine the roots of the orchid, and remove damaged or dead parts that appear black, mushy, or paper thin. Healthy roots are firm and plump.
  3. Try teasing apart some of the roots and stems. If they can't tease apart by hand, use a sharp, sterile cutting tool.
  4. Repot each plant in new medium, stake if necessary, and water.

Potting and Repotting Orchids

If your orchid's roots are growing out of the pot and/or the growing medium has completely broken down, it’s time to repot. Wait until you're sure your plant is done flowering before repotting your orchid. Here's how:

  1. Gently remove the orchid from its old container, moistening the growing medium as necessary to make it easier to slide the plant out.
  2. Cut away any dead or damaged roots with a sterile cutting tool.
  3. Set the orchid in a slightly larger container, and fill around it with fresh growing medium.
  4. Because the roots won't be anchored to the medium yet, you can stake the plant if necessary to help it stay upright. Eventually, new roots will grow through the medium and attach to the pot itself, which will anchor your plant.

Common Pests & Plant Diseases

Orchids don't tend to have major pest problems. But they can be appetizing for common plant pests, including aphids, fungus gnats, mealybugs, spider mites, scale, cigar-shaped thrips, and whiteflies. Most pests can be eliminated with a gentle brush of the hand, a jet of water, or washing with soapy water to reduce the insect populations. You can also dab rubbing alcohol or mix alcohol with a few drops of liquid dish soap and then gently spray the insects as a way to damage their bodies. Another solution for insect removal is neem oil, which can smother pests.

Furthermore, besides root rot, orchids also can become afflicted with various fungal diseases, such as anthracnose, phytophthora (black spots on leaves), botrytis, leaf algae, and petal blight.

How to Get Orchids to Bloom

Your orchid should bloom at least once a year if not more, though species vary in blooming cycles. And the flowers generally last two to four months on average.

It can be disheartening to see a flowerless orchid that once beautifully bloomed. Some orchids can be stimulated to bloom if the temperature goes down for a few nights, such as the phalaenopsis orchid, which is luckily one of the most popular plants sold as houseplants. But otherwise, ensuring a bloom from your orchid is generally all about providing the proper light, moisture, temperature, humidity, food, and growing medium.

Common Problems With Orchids

Once an orchid finds a suitable spotand falls into a routine, the plant should produce healthy growth and eventually reward you with a beautiful bloom. But subpar conditions can result in some common problems.

Leaves Shriveled and Wrinkled

Shriveled and wrinkled leaves indicate that the orchid is not getting enough water. The culprit is often unhealthy roots. Roots should appear plump and white or green. If the roots appear healthy, that likely means the plant is being underwatered. But if roots are black and mushy, use a sterile cutting tool to eliminate the bad roots, and repot the orchid in new growing medium. Then, make sure you're allowing the plant to dry out between waterings.

Leaves Turning Yellow

Overwatering and consequently root rot are often the cause of yellowing leaves. Make sure you're giving your orchid time to dry out between waterings. If that doesn't work, repot the plant and remove any unhealthy roots.

Buds Dropping

If you see buds dropping from the plant before they bloom, the plant is stressed for any number of reasons. This is when you will need to investigate the orchid's environment and potentially move it to a better spot. Look for the following possible issues:

  • The plant is being under watered or over watered.
  • The orchid is experiencing swings in temperature because it is near a heating vent, air conditioner, or some other draft.
  • The plant is sensitive to nearby chemical fumes (paint or gas, for example).
  • The orchid is sensitive to nearby plants or fruits producing ethylene gas.
  • The orchid is in a low-humidity spot.
  • There's a possible pest infestation.


  • Are orchids easy to grow?

    Orchids are easier to grow than you might think, as long as the plant lives in the right conditions.

  • When is an orchid considered to be rare?

    An orchid is designated as rare if its natural habitat is no longer viable or if it has a highly unusual pigmentation. For example, the ghost orchid is considered rare and endangered, but you might be able to purchase this and other hard-to-find orchids at specialty florists.

  • How long can an orchid live?

    Most orchids seem almost indestructible and can live a very long life—for decades or more—given the right environment.
