Prof. Samuel Fitzgerald, Ph.D.Beginning to learn how to care for orchids can start with some of the more common and easily grown varieties such as Phalaenopsis.
Use the commercially prepared specialty orchid potting mix that has a wood bark and perlite mixture, as orchids require root aeration.
You should water orchids only when the growing media has dried out, which will typically occur every seven to ten days to prevent root rot.
Provide bright indirect light for best performance and drop temperatures at nighttime by 10 degrees Fahrenheit to initiate blooming for orchids that need a temperature dip.
Yellow leaves typically indicate problems with the roots, so you want to check on roots when this occurs and improve the drainage conditions.
When plants are growing, apply a 30-10-10 fertilizer every other week, but do not apply while the plant is blooming.

Orchids are commonly viewed as requiring specialized knowledge and skills to care for. However, I realized that caring for orchids can be approached simply with hands-on methods to care for these beautiful plants. Orchids are well-suited to grow inside a residence. I have cared for my first orchid for years using general orchid care techniques. Do not let myths about expectations and unrealistic expectations lead you to believe you cannot care for orchids. The success of orchid care is based on regular routines.
We'll make caring for light amounts, watering, potting, and reblooming easy. Caring for orchids is like baking bread: first, measure every ingredient precisely; next, follow the timing of each step; then - enjoy the results. I will share with you advice based on the science I've used in my greenhouse, which will help you avoid the most common problems and achieve success and vibrant orchid blooms every time.
Begin with the basics. Set plants in bright areas with indirect sunlight, and wait until the mix is dry before watering. Repot every two years. You will build confidence with these simple actions. My orchids bloom year after year with minimal effort. You will be successful with these tried and true strategies.
Choosing Beginner-Friendly Orchids
To begin, Phalaenopsis orchids are a forgiving type of orchid that can withstand minor errors. I recommend them to every newbie grower. They are simple because their thick leaves store plenty of water. The hybrid varieties are spectacular and come in a wide range of colors. You really do get a very hardy plant that is bred to perform well in a home environment. They are perfect for your first experience.
Light requirements can vary widely. Phalaenopsis orchids do just fine in low-light conditions next to an east-facing window. In contrast, higher-light orchids, such as Cattleyas, thrive in the sunny south exposure. My first Cattleya burned its leaves - an unfortunate lesson I learned the hard way! The arrangement and placement are key. Just remember, all these conditions above are dependent on the natural light in your home!
Always choose adult plants. Seedlings are more challenging to care for because they require optimal humidity and regular feeding. Mature orchids can handle changes in culture. I do not like to sell seedlings to new growers. Mature orchid results will show you much faster. You can build your confidence very quickly with the hardiness of mature plants.
Hybrids offer disease resistance and a longer blooming period. I have firsthand experience testing these in a greenhouse. They are designed by a team of scientists to adapt to standard home temperatures. You will have vivid colors for months. Start small, then venture into the less common varieties when you are comfortable.
Potting Mix and Container Essentials
Conventionally packaged potting soil actually suffocates orchid roots. Orchids require air circulation around their roots. Potting soil compacts too easily and retains excessive moisture, leading to root rot within a short period. I lost another three plants because I didn't understand this concept. Use potting soil specifically made for orchids, or you will likely lose them.
When it comes to a quality orchid mix, there are three key components. *Bark* provides structure and drainage, while *perlite* enhances airflow around the root zone. Finally, *charcoal* helps to prevent the growth of unwanted fungi naturally. In my mix, I use *equal parts* of these ingredients, which creates an open and airy environment that orchids love.
Selecting a container can significantly affect the health of the roots. Clear plastic pots allow easy moisture monitoring. Terracotta has good aeration capability but dries out quickly. Ceramic may look nice, but it usually does not have drainage. I always suggest plastic pots for everyone. Don't skimp on drainage holes.
Proper drainage is essential. Orchids will drown if water cannot escape, so I drill extra holes in all containers to ensure proper drainage. It is also best to elevate your pots with pot stands or pebbles to mimic their natural habitat, where they perch on trees above the soil. Ensure the orchid has proper drainage, and it will reward you with lots of vigorous growth.
Seasonal Care Adjustments
During the spring and summer months, new growth periods are starting to occur. Your orchids will also require more water and nutrients, so they need an increase in watering (soaking weekly). Use a 30-10-10 fertilizer about every 2 weeks. I look for new leaves and roots as an indication that your plant is happy and healthy, and you should encourage the plant to use this energy as much as possible during these months.
The fall season initiates particular blooming mechanisms. This process of flowering begins with cooler night temperatures in the range of 55-65 degrees Fahrenheit. Gradually reduce watering at this time. Once blooms are spotted, initiate a 10-30-20 fertilizer every month. If you make this temperature change, my orchids bloom consistently. You must provide the temperature drop as they experience these lower temperatures in their natural habitat.
Dormancy care is essential throughout the winter. In winter, limit watering to once a month and refrain from fertilizing altogether, watering only when the mix feels bone dry. Move plants completely out of any cold drafts by windows. This care will help them conserve energy during the rest period and emerge strong in the spring.
Be precise when adjusting ratios, as you've learned, watering in the summer decreases by 50% compared to winter. Fertilizer strength also decreases, documented in your garden journal. You don't need to worry about root rot or nutrient burn. Understanding how to adjust for each season will keep your orchids safe!
Troubleshooting Common Problems
The yellow leaves indicate overwatering problems. Check the roots immediately for mushiness. Let the soil dry completely before watering again. A long-term solution is better drainage. I repot plants that don't seem to be recovering in a new bark mix. This prevents future root rot.
Dehydration stress is usually evident when you see certain orchids with wrinkled leaves, so soak your orchid pots (not the orchids) for 20 minutes at this time. Watering needs to be on a regular schedule, which you can establish later. Brown leaf tips indicate salt buildup, so drain the pots and immediately flush them with pure water. For permanent prevention, you can install humidity trays. I have had contested success in recovering orchids by following this method.
To correct missed bloomings, make adjustments for light. Now is a good time to move plants into brighter situations. You can let the temperatures drop in the following season. If your bloom drops, it is important to reposition immediately. Move the plants away from fruit and vents. You will want to maintain stable temperatures in the long term. I keep track of the blooming cycles in my journal.
The black roots of the orchid require immediate intervention. Cut away the dead roots with sanitized scissors. Repot without delay in a well-aerated mix. To keep them from declining again, you must check the root health every month. Choose clear containers so you can observe the roots and assess their health, as well as identify if they appear dead again. My orchids were saved after I made these changes with rescues.
10 Essential Orchid Care Tips
Orchids thrive in bright indirect light positioned adjacent to east or west-facing windows. For example, if leaves become deep green, the lighting is insufficient. If the edges of the leaves turn reddish, it indicates that there is too much sunlight. It is a good idea to rotate your orchids every quarter to minimize uneven growth. Consistent bright indirect lighting will yield consistent photosynthesis, ultimately leading to uniform growth as well.
Water only if the potting mix feels dry. Every week, soak the pots for 20 minutes, and then let them drain completely afterward. Do not wet the crown, but when potting, it should not slide through the pot's hole - if it does, you need more substrate. Reduce watering in winter when the orchid is dormant. The roots of the orchid will feel firm and have a silvery-green appearance when properly hydrated.
Use a pebble tray to maintain a humidity level between 40% and 70%. Always ensure pots are above the waterline. Placing plants together also acts as a microclimate. In dry seasons, use humidifiers. Digital hygrometers will accurately monitor. Maintaining proper moisture levels will prevent wrinkled leaves and dropping buds.
Use a 30-10-10 fertilizer every other week when actively growing. Change to half-strength 10-30-20 formula in fall. Always fertilize moist soil. Flush pots once a month to avoid salt buildup. Suspension of feeding during the bloom phase will help extend the flower life.
Optimal Light Placement
- Position orchids near east or west-facing windows for bright, indirect light
- Use sheer curtains to diffuse intense south-facing sunlight
- Monitor leaf color: deep green indicates insufficient light
- Reddish leaf edges signal too much direct sun exposure
- Rotate plants quarterly for even growth distribution
- Supplement with grow lights if natural light is inadequate
Proper Watering Technique
- Submerge pots in tepid water for 20 minutes weekly
- Drain completely until no water drips from bottom
- Water only when potting mix feels dry to the touch
- Use room-temperature water to prevent root shock
- Avoid wetting the crown where leaves meet stem
- Reduce frequency to every 10-14 days during winter
Humidity Management
- Maintain 40-70% humidity using pebble-filled trays
- Ensure pots sit above waterline, not submerged
- Group plants together to create microclimates
- Use humidifiers during dry winter months
- Avoid misting leaves to prevent fungal issues
- Monitor with digital hygrometers for accuracy
Seasonal Fertilization
- Apply 30-10-10 fertilizer every two weeks in spring/summer
- Switch to half-strength 10-30-20 formula in fall/winter
- Always fertilize moist soil to prevent root burn
- Flush pots with pure water monthly to prevent salt buildup
- Suspend feeding during blooming phases
- Use liquid fertilizers for even distribution
Timely Repotting
- Repot every 1-2 years after flowering finishes
- Use fresh orchid-specific mix for optimal drainage
- Select pots just 1-2 inches larger than root ball
- Trim dead roots with sterilized pruning shears
- Soak new mix after repotting to settle media
- Wait 1 week before resuming normal watering
Pruning Strategy
- Cut spent flower spikes above first node below blooms
- Remove only yellowed or damaged leaves
- Sterilize tools with 70% isopropyl alcohol between cuts
- Apply cinnamon powder to cut surfaces as natural antiseptic
- Avoid cutting green pseudobulbs on sympodial orchids
- Prune during active growth periods for faster recovery
Air Circulation
- Provide gentle air movement with oscillating fans
- Space plants 6-12 inches apart for ventilation
- Avoid direct drafts from heating/cooling vents
- Open windows during mild weather for fresh air exchange
- Use ceiling fans on low settings in enclosed spaces
- Ensure airflow reaches both foliage and root zones
Temperature Regulation
- Maintain 75°F (24°C) daytime temperatures
- Provide 10°F (6°C) nighttime temperature drops
- Expose to 55-65°F (13-18°C) nights in fall for blooming
- Avoid sudden temperature swings exceeding 15°F (8°C)
- Use thermometers to monitor microclimate conditions
- Move plants away from cold windows in winter
Sun Protection
- Filter direct sunlight using 30%-40% shade cloth
- Position plants 3-5 feet back from south-facing windows
- Acclimate gradually to brighter locations over 7-10 days
- Check leaves daily during heatwaves for scorch signs
- Use UV-protective films on intense exposure windows
- Relocate plants during summer midday sun peaks
Root Health Monitoring
- Inspect roots monthly through clear plastic pots
- Healthy roots appear firm and silvery-green when dry
- Bright green coloration indicates proper hydration
- Trim brown/mushy roots with sterilized scissors immediately
- Repot if over 30% of roots show damage
- Disinfect tools with 10% bleach solution between plants
5 Common Myths
To preserve their delicate tropical nature and prevent dehydration in the home environment, orchid plants should be watered daily.
In fact, over watering is the number one cause of orchid death. These epiphytic plants have adapted evolutionarily to wet-dry conditions, so they prefer their roots to dry in between waterings. Most orchids will be happy being watered only when the potting medium is completely dry, typically every 7-14 days, depending on humidity and time of year. The daily moisture eventually will suffocate the roots by blocking oxygen exchange, while also providing an ideal environment for fungi and other organisms that cause root rot (death). The velamen, a spongy covering on the roots, stores enough moisture to sustain the plants between waterings.
All orchid species will thrive when planted in standard potting soil commonly used for other houseplants.
Approximately 70% of cultivated orchids are epiphytes that naturally grow on trees with exposed roots. Standard soil compacts around their roots, preventing essential air circulation and causing fatal rot. Specialized orchid mixes contain large chunks of fir bark, perlite, and charcoal that recreate the airy conditions of their native habitats. Terrestrial orchids like some Paphiopedilum varieties are exceptions but still require exceptional drainage. Using inappropriate media is the second most common reason for orchid failure after overwatering.
Direct sunlight exposure throughout the day significantly increases blooming frequency for all orchid varieties.
While some orchids like Vanda and Cattleya tolerate direct morning sun, most popular varieties (including Phalaenopsis) suffer irreversible leaf damage under intense sunlight. Their natural habitats are forest canopies with dappled light, not full sun exposure. Optimal lighting involves bright indirect light - east-facing windows are ideal for providing gentle morning illumination. If leaves develop bleached spots, reddish edges, or unusual warmth to the touch, immediate relocation to shadier conditions is required. Supplemental artificial lighting is safer than risking sun damage.
With perfect care and ideal growing conditions, orchid flowers should remain vibrant and intact indefinitely.
Blooms lasting 6-12 weeks represent normal physiological duration for most orchid species, determined by genetic factors rather than care quality. After flowering, orchids enter essential vegetative growth phases to rebuild energy stores through photosynthesis. The popular Phalaenopsis typically blooms annually, while Cattleyas may flower every 9 months. Premature bud drop indicates stress, but natural flower senescence after 2-3 months is inevitable. Expect healthy plants to require 6-9 months between blooming cycles even under optimal conditions.
Every kind of orchid contains very dangerous chemicals and all of those chemicals are toxic for kids and pets.
The ASPCA expressly states that the majority of common orchids (e.g., Phalaenopsis or moth, Cattleya and Dendrobium) are not toxic to felines or canines, nor to humans. Absorption into the stomach can cause an upset stomach, because of cellulose in the plant; however, no commercially available orchids have lethal poisons. This misunderstanding likely arose from mixing up orchids with true lilies (Lilium species), which are very toxic to cats and cause kidney failure. Some rare varieties of orchid, notably Lady Slipper, have some mild irritants, but these would require a large amount of the plant to cause significant poisoning. Nevertheless, it is always best to discourage chewing behavior to prevent ingesting a large enough amount of any hazardous substance to cause choking.
Conclusion
You will find that working successfully with orchids is about the epiphytic lifestyle of orchids*. In nature, orchids grow on trees, where the roots are exposed and receive moisture. Use a potting medium that provides airflow and drainage, mimicking their natural habitat. The care you provide should best reflect their unique biology.
Grow your patience with the plant's growth cycles. Orchids are slower to develop than many of the houseplants you're familiar with. Blooms may take months to return. My first rebloom was ten months after I had the orchid. Trust in the process of that cycle. Your care and consistent steps contribute to these amazing bloom cycles over time.
Start with the forgiving Phalaenopsis varieties. They will be the easiest to manage, as they are the first to understand their care. Then, try the more challenging varieties, such as Cattleyas. I started with two moth orchids, and now I manage 15 different varieties. You can build confidence in your abilities systematically.
Today, use a different strategy. Perhaps shift the light location or check if the potting mix is dry. Small steps can lead to significant changes. My students have reported success in a few weeks. Your orchid will thank you with healthier growth and some successful flowering.

Frequently Asked Questions
How do you care for an indoor orchid?
Proper indoor orchid care requires bright indirect light near east/west windows, weekly soaking when potting mix dries, specialized bark-based media, 40-70% humidity, and monthly fertilizer during growth phases. Maintain 10°F nighttime temperature drops to trigger blooming cycles.
What should you do after orchid blooms fall off?
After blooms drop, cut the spike above the first node using sterilized tools. Reduce watering frequency and suspend fertilization during the dormancy period. Repot if roots outgrow the container, using fresh orchid mix to support new growth.
Where is the optimal placement for orchids indoors?
The best locations provide:
- East or west-facing windows with sheer curtains
- Areas with bright indirect light avoiding direct afternoon sun
- Spaces maintaining 40-70% humidity via pebble trays
- Locations away from heating/cooling vents and ripening fruit
How frequently should orchids be watered?
Watering frequency depends on:
- Season (weekly in summer, monthly in winter)
- Potting media (bark dries faster than moss)
- Environment (higher heat/humidity increases needs)
- Always water only when mix is completely dry
Should orchids be watered with ice cubes?
Ice cubes aren't recommended as cold temperatures shock tropical roots, causing damage. Use room-temperature water instead. Submerge pots for 20 minutes then drain completely. This mimics natural rainfall while preventing crown rot from standing water.
What are critical mistakes to avoid with orchids?
Never:
- Use standard potting soil (causes root suffocation)
- Water on rigid schedules (check moisture first)
- Place in direct southern sunlight (scorches leaves)
- Fertilize dry roots (causes chemical burns)
- Ignore yellowing leaves (indicates health issues)
How can you revive a struggling orchid?
First identify the issue through symptoms like wrinkled leaves or black roots. Then:
- Trim dead roots with sterilized scissors
- Repot in fresh orchid-specific mix
- Adjust lighting to bright indirect exposure
- Establish proper watering technique
- Suspend fertilization during recovery
Are clear pots necessary for orchids?
Clear pots allow essential root monitoring for health assessment. Healthy roots appear silvery-green when dry and bright green when moist. This visibility helps detect early rot while enabling photosynthesis in chlorophyll-containing roots. Plastic is preferred over ceramic for breathability.
What indicates an orchid needs repotting?
Repot when you observe:
- Roots circling container or growing through drainage holes
- Potting media breaking down into dense particles
- Water pooling instead of draining quickly
- Plant becoming top-heavy and unstable
- Persistent moisture despite reduced watering
Can tap water be used for orchids?
Tap water often contains minerals causing leaf tip burn and media salt buildup. Use filtered, distilled, or rainwater instead. If using tap water, flush pots monthly to remove deposits. Avoid softened water containing sodium damaging to root systems.
