The Fuss About Watering Orchids the Right Way
Orchids, with their vibrant colors and intricate blooms, are a popular choice for home gardeners and indoor flower enthusiastsI However, these exotic blooms often have a reputation for being finicky when it comes to watering. Thus, understanding their needs and following a few simple guidelines can ensure your orchid flowers thrive. If you are just starting out with orchids, I recommeding reading this beginner’s guide to caring for orchid plants that I wrote here.
Factors Influencing Watering Frequency for Orchids
Several factors influence how often you should water your orchids:
- Orchid Type: Different orchid species have varying water requirements. For example, Phalaenopsis orchids prefer evenly moist conditions, while Cattleyas prefer to dry out between waterings.
- Potting Medium: The type of potting medium affects how quickly it dries. Bark-based mixes dry faster than sphagnum moss.
- Temperature and Humidity: Higher temperatures and lower humidity lead to faster drying.
- Light Exposure: Orchids in brighter light need more frequent watering.
- Season: Orchids generally require more water during active growth periods (spring and summer) and less during dormancy (winter).
1. Watering Based on Orchid Type
The orchid family boasts over 28,000 species, each with its own unique preferences.
- Phalaenopsis (Moth Orchids): These popular orchids, often found in grocery stores, prefer consistently moist (but not soggy) conditions. Think of their natural habitat in the humid rainforests—they like a bit of moisture around their roots. Allow the potting mix to dry slightly between waterings to prevent root rot.
- Cattleya: These orchids, known for their showy blooms, prefer a more cyclical watering pattern. They like to dry out slightly between waterings, mimicking their natural epiphytic lifestyle where they experience periods of rain followed by drier conditions. According to the American Orchid Society, Cattleyas thrive when their roots have a chance to dry before being watered again.
- Oncidium (Dancing Lady Orchids): These orchids, with their cascading sprays of small flowers, prefer a slightly drier environment. Allow the potting mix to dry almost completely before watering again.
Not sure what kind of orchid you have? Contact your local cooperative extension service as they can help you properly identify your orchid flower.
2. Potting Medium: The Foundation of Orchid Health
The type of potting mix you use plays a crucial role in how often you need to water your orchid.
- Bark-based Mixes: These mixes, often made from fir bark, are popular for their excellent drainage. They dry out relatively quickly, requiring more frequent watering. Reasearch has shown that bark-based mixes dry out faster than other media, making them ideal for orchids that prefer to dry between waterings.
- Sphagnum Moss: This moisture-retentive medium stays damp for longer periods, requiring less frequent watering. Sphagnum moss can retain significantly more water than bark mixes, making it suitable for orchids that prefer consistently moist conditions.
For my orchids, I use a well-draining potting mix that allows their roots to breathe. A standard mix consists of:
- Orchid Bark: Provides excellent air circulation.
- Perlite: Improves drainage and prevents the mix from becoming soggy.
- Sphagnum Moss: Helps retain moisture.
3. Temperature and Humidity: Creating a Microclimate
Orchids are sensitive to temperature and humidity fluctuations.
- Higher Temperatures: As temperatures rise, the potting mix dries out more quickly, increasing the need for watering. It is a good idea to increase watering frequency during hot summer months.
- Lower Humidity: Dry air can cause moisture to evaporate from the potting mix faster, requiring more frequent watering. It’s also a really good idea to increase humidity around orchids by using a humidifier like this one or placing the pot on a tray of pebbles filled with water.
4. Light Exposure: Fueling Growth and Water Needs
The amount of light your orchid receives directly impacts its water consumption. Orchids in brighter light conditions photosynthesize more actively, leading to increased water usage and the need for more frequent watering. Thus, orchids in bright, indirect light may need more frequent watering than those in lower light conditions.

5. Seasonal Shifts: Adapting to Nature’s Rhythm
Orchids, like many plants, have periods of active growth and dormancy.
- Active Growth (Spring and Summer): During these seasons, orchids require more frequent watering to support their increased growth and blooming. It is a good idea to increase watering frequency during their active growth periods.
- Dormancy (Winter): As growth slows down in winter, orchids need less frequent watering. It’s a good idea to reduce watering frequency for orchids during winter months to prevent overwatering and root rot.
By understanding these factors and observing your orchid’s individual needs, you can develop a watering routine that keeps your plant happy, healthy, and blooming.
Signs Your Orchid Needs Watering
- Weight of the Pot: Lift the pot – if it feels unusually light, it’s time to water.
- Color of the Roots: Healthy roots are typically green or white when moist and silvery-gray when dry. I usually keep my orchids in clear plastic planters so I can lift them out of their decorative pot and check the root system without disturbing the plant.
- Moisture Meter: A moisture meter can provide a more accurate assessment of the moisture level in the potting mix.
Watering Techniques
- Soaking Method: Submerge the pot in a container of room-temperature water for 10-15 minutes, allowing the potting mix to thoroughly absorb the water.
- Top-Down Watering: Pour water over the potting mix until it flows out of the drainage holes.
Important Considerations
- Avoid Overwatering: Overwatering is a common cause of orchid death. Allow the potting mix to dry out slightly between waterings.
- Water Quality: Use filtered or rainwater to avoid mineral buildup in the potting mix.
- Drainage: Ensure the pot has drainage holes to prevent water from accumulating at the bottom.
Additional Tips
- Increase humidity around your orchids by placing them on a tray of pebbles filled with water or using a humidifier.
- Fertilize your orchids regularly during their active growth periods.
- Repot your orchids every 1-2 years into fresh potting mix.
Watering Orchids With Ice Cubes – Is It a Good Idea?
You might have heard that watering orchids with ice cubes is a surefire way to kill them. But is this really true? Surprisingly, the answer is a resounding no. Research from cooperative extensions have shown that using ice cubes to water Phalaenopsis orchids (the most common type found in stores) is safe and may even be beneficial.
Why Ice Cubes Can Work
- Slow and Steady Wins the Race: Ice cubes melt gradually, providing a slow and steady supply of water to the roots, mimicking the way orchids receive moisture in their natural environment. This helps prevent overwatering, a common cause of orchid demise.
- No Shock to the System: While orchids are tropical plants, the studies found that the temporary cooling effect of the ice cubes didn’t harm the orchids’ roots or overall health.
Important Considerations Before You Try Watering Orchids With Ice Cubes
- Orchid Variety: This method has been primarily tested on Phalaenopsis orchids. While it might work for other types, it’s always best to research the specific needs of your orchid variety.
- Placement Matters: Avoid placing ice cubes directly against the leaves or delicate new roots, as this could cause damage. Aim for the potting medium, away from the plant’s base.
- Water Quality Counts: Use filtered water to make your ice cubes, as impurities in tap water can build up in the potting mix over time.
The Verdict on Watering Orchids With Ice Cubes
While the idea of using ice cubes might seem unusual, it can be a convenient and effective way to water your Phalaenopsis orchids, especially if you tend to overwater. Just remember to use this method with caution, observe your plant’s response, and adjust as needed.
That said…Do I use ice cubes to water my orchids? No. And it’s because I believe that ice cubes are not natural to their growing environment and prefer not to shock the root system with meltnig ice water, particularly during the colder and darker months of the year.
There was a time when I watered my phalaenopsis orchids with them, but have moved away from the practice entirely. There is division on this topic so whether or not to water with ice cubes is a personal decision.
