Home gardening is a great way to grow beautiful plants while creating a relaxing environment in your home. Orchids are one of the most beautiful and exotic flowers that you can grow indoors. But what if you lack the time to constantly water them, or they’re out of reach? Water-only orchid growing is your answer! This technique only requires you to give them the necessary nutrients that the plant needs to thrive in water. If orchid growing isn’t your forte, this post will teach you how to grow an orchid in water. And which orchid types are the best fit for this method.
What Types of Orchids can be Grown in Water
Phalaenopsis orchids, often referred as “Moth Orchids,” are an excellent variety for water culture. These orchids are known for their resilience and adaptability, making them a suitable choice for beginners trying the water-only growing method. Phalaenopsis orchids have broad leaves and produce stunning, long-lasting flowers, making them a striking addition to any indoor garden. Remember, for successful water culture, maintaining cleanliness and using the right type of water—generally rainwater or distilled water—is crucial.
How to Grow Orchids in Water
Growing orchids in water, also known as water culture, is a simple process that requires minimal maintenance, making it a convenient solution for busy plant owners. As discussed above the Moth Orchids are perfect for water culture growing. Once you master this branch out to experimenting with other Phalaenopsis Orchids.
Among the Phalaenopsis orchids suitable for water culture, the Phalaenopsis amabilis, also known as the Moon Orchid, is a popular choice. Its elegant white flowers make it a classic choice for indoor gardeners. Another variety, the Phalaenopsis aphrodite, is renowned for its large, round flowers. The Phalaenopsis schilleriana is another excellent variety for water culture, its distinctive pink flowers and mottled leaves add a unique touch to your indoor space.
Choosing the Right Container
Choosing the right container plays a pivotal role in the successful water culture of orchids. Since orchids do not require soil, any transparent container that can hold water and the orchid plant will suffice. Clear glass vases or mason jars are popular choices among indoor gardeners. The transparency allows sunlight to reach the roots. Also makes it easier for you to monitor the water level and root growth. However, keep in mind that the container’s opening should be wide enough to accommodate the plant without damaging the leaves or roots. To create an optimal growing environment, ensure ample room for air circulation around and within the root area. This prevents bacterial and fungal growth, which could jeopardize your orchid’s health.
Prepare the Orchid
Preparing the orchid for water culture is an essential step. Begin by choosing a healthy Phalaenopsis orchid, preferably one that’s not currently blooming. Remove the orchid from its current medium carefully, ensuring you do not damage the roots. All the bark or moss should be gently cleaned off from the roots.
Examine the root system meticulously. If you find any rotted or dead roots, trim them off with a clean, sharp pair of pruning shears. It’s important to sterilize the shears before and after use to prevent the spread of diseases. After this, thoroughly rinse the roots under lukewarm water to eliminate any remaining potting medium and potential pathogens.
Once your orchid is clean and trimmed, it’s time to move it into its new water home. Remember, the orchid should not be completely submerged in the water; instead, the water level should just reach the base of the plant. The roots need access to air, so use a clear container that allows you to monitor the water level and the condition of the roots easily.
Ensuring a proper setup from the start will facilitate a smooth transition for your orchid into water culture and set the stage for flourishing growth.
Water and When to Change the Water
The water you use for your orchid is critical to its health and growth. Rainwater or distilled water are your best options due to their lack of chemicals. If this is not available, tap water can be used, but be sure to let it sit out for 24 hours to allow chlorine and other potentially harmful elements to evaporate.
Changing the water regularly is vital to prevent the buildup of salt and mineral deposits that can harm your orchid. A weekly water change is generally recommended. When you change the water, make sure to rinse the container thoroughly to remove any algae or mineral deposits.
To change the water, gently lift the orchid out of the container, empty the old water, rinse the container, and refill it with fresh water. Do not overfill the container; the water level should only reach the base of the plant, and the roots should not be fully submerged. Once the container is filled, carefully place the orchid back into the water.
Monitoring the color and appearance of the roots can provide insights into the health of your orchid. Healthy orchid roots are usually a vibrant green when wet and white or silvery when dry. If you observe any discoloration, mushiness, or foul smell, it could indicate root rot, which requires immediate attention.
By managing the water quality and regularly changing it, you can ensure your orchid thrives in its water-based home.
Light and Temperature
The right light and temperature conditions are essential factors for the healthy growth of orchids in water culture. Light plays a crucial role in photosynthesis, the process by which plants produce their food. Phalaenopsis orchids thrive under diffused, indirect light. Avoid subjecting your orchid to direct sunlight, as the intense rays can scorch the leaves. Placing your orchid near a north or east-facing window is typically a good choice. If natural light is not sufficient, fluorescent lights designed for indoor plants can also be used.
As for temperature, Phalaenopsis orchids prefer a relatively stable climate, ideally between 65-80°F (18-27°C) during the day, and a slight drop at night. Avoid drastic temperature changes, as they can stress the plant and impede growth. Keep your orchid away from drafts, heating vents, or air conditioners to maintain consistent temperature conditions. Careful management of light and temperature conditions will optimize your orchid’s health and promote prolific blooming.
Fertilization
Just like any other plant, Phalaenopsis orchids in water culture require nutrients to grow and flower optimally. Regular fertilization, typically once a month, should be a part of your orchid care routine. A balanced orchid fertilizer, which has equal amounts of nitrogen, phosphorus, and potassium, is ideal for most growth stages of the orchid. However, during the blooming phase, a bloom booster fertilizer with higher phosphorus content can be more beneficial.
The process of fertilizing your water-cultured orchid is pretty straightforward. First, remove the orchid from its water container and empty the water. Then, prepare the fertilizer solution according to the package instructions, ensuring it’s thoroughly mixed. Pour the fertilizer solution into the container until it reaches the base of the plant, but make sure the roots are not fully submerged. After the fertilizer has been in contact with the roots for about 15 minutes, discard the solution and refill the container with fresh water.
Take note that over-fertilization can be harmful to your orchid, leading to root burn, leaf tip burn, and even plant death. To prevent this, always follow the recommended fertilizer doses and avoid fertilization if the orchid appears stressed or unhealthy. By providing the necessary nutrients through fertilization, you can boost your orchid’s health and encourage lush growth and vibrant blooms.
Care After Bloom and Encouraging Reblooming in Water Culture
After your Phalaenopsis orchid has finished blooming, it enters a rest period, known as dormancy. During this time, your orchid conserves energy and prepares for the next blooming cycle. Do not be alarmed if your orchid drops its flowers; this is a natural part of its lifecycle.
To care for your orchid after blooming, continue the same basic care routine: changing the water weekly, providing adequate light, maintaining stable temperature conditions, and monthly fertilization. However, you can reduce the frequency of fertilization to every six weeks during this rest period as the nutrient demand is lower.
The old flower spike can be pruned to encourage the growth of a new spike. Use a sterilized pair of pruning shears to cut the spike about one inch above a node, or bump, on the stem. The node is a potential growth point for a new flower spike.
Reblooming in water culture is largely influenced by the light and temperature conditions. As we move into fall and the days get shorter, reduce the amount of light your orchid receives by about one hour each day. Simultaneously, try to provide a slight drop in temperature, ideally to around 55-65°F (13-18°C) at night. This simulates the natural environment of the orchid, triggering the production of a new flower spike.
Remember, patience is key during this phase. It can take several months for a new spike to develop and even longer for the first buds to open. With consistent care and optimal conditions, your water-cultured orchid can rebloom, showcasing its stunning flowers once again.
Repotting or Upsizing Vase in Water Culture
In water culture, the term ‘repotting’ is akin to moving your orchid to a larger vase. This is often necessary as the orchid grows and the roots become too cramped in the current container. Observing your orchid’s roots can give a clear indication of when it might need a larger home. If the roots are constantly pushing against the sides of the container or growing out of the top, it’s a good sign that it’s time to upgrade to a larger vase.
When upsizing, choose a clear vase that’s just slightly larger than the current one. The roots should have room to grow and spread, but too much space can result in excessive water, potentially leading to root rot. The new vase should also be tall enough to support the plant’s height.
To repot, gently remove the orchid from its current container, being careful not to damage the roots. Rinse the roots under tepid water to remove any remaining old water. Place the orchid into the new vase and fill it with fresh water to the base of the plant, ensuring the roots are not fully submerged. Continue with your regular care routine in the new vase.
Remember, repotting or upsizing is also a great opportunity to inspect the roots closely and trim off any unhealthy or dead roots. This helps keep your orchid healthy and promote better growth in its new home.
