If you’ve ever received or bought a Phalaenopsis orchid, you’ve probably wondered: how can you care for it so it blooms year after year? Caring for a Phalaenopsis orchid isn’t complicated, but there are a few basic things you need to pay attention to. In this article, I’ll share the essential details of Phalaenopsis orchid care, including tips on watering, fertilizing, light requirements, and repotting, to ensure that these stunning plants stay healthy and vibrant in your home for the long term
Phalaenopsis orchids are native to tropical rainforests, where they live on trees and anchor themselves in the crevices of bark with their aerial roots. This epiphytic lifestyle requires unique care in a home environment. Since the plant’s aerial roots photosynthesize, they need sunlight, making it best to keep them in a transparent pot. This allows the roots to develop properly.
Orchids are typically sold in a mix of bark and peat, which is optimal for nutrient absorption. If you’re feeling adventurous, you can even try growing them hydroponically, although this method is recommended for more experienced orchid growers as it requires special techniques.
A transparent pot is not just an aesthetic choice but also plays a functional role in Phalaenopsis orchid care. Since the plant’s aerial roots photosynthesize, they need light, which they can only receive if the pot is transparent. This allows the roots to access sunlight, which is crucial for the plant’s healthy growth.
Light requirements
Light is one of the most crucial factors affecting the health and blooming of Phalaenopsis orchids. Since these plants originate from rainforests, where they receive filtered light through the canopy, direct sunlight can be harmful. Phalaenopsis orchids thrive best in east or west-facing windows where they receive indirect light instead of direct sunlight.
In the summer, it’s a good idea to place them outside in a shady spot where they can enjoy fresh air and the beneficial effects of sunlight. This can help the plant bloom profusely later on. Just be careful not to expose the plant to too much direct sunlight, as this can scorch the leaves. In winter, when light levels are lower, make sure the plant doesn’t get too cold near the window.
In my own experience, after a summer of keeping my orchid outdoors, I encountered an unexpected problem: a slug attacked the plant, taking a large chunk out of it. Fortunately, I noticed the damage in time and was able to save the plant. This experience highlights the importance of regularly checking on your plants if you keep them outside to avoid or minimize such damage.
Watering
Watering is another key factor in caring for Phalaenopsis orchids. There are two main watering methods: top-watering and soaking. Both methods are effective, as long as you ensure your plant doesn’t go without water for too long.
When watering Phalaenopsis orchids, be careful not to let the roots sit in water for extended periods, as this can lead to root rot. For the soaking method, place the plant in a bowl of water for about 10-15 minutes, then let the excess water drain off. It’s crucial that the orchid’s roots never remain submerged in water, as this can easily lead to fungal infections.
The frequency of watering depends on environmental factors like temperature and humidity. Generally, they need more water in summer and less in winter. If you notice the leaves becoming wrinkled and limp, it’s a sign that the plant is thirsty and needs immediate watering.
Fertilizing
Supplementing nutrients is also essential for maintaining the health of Phalaenopsis orchids. Use a special orchid fertilizer, which is readily available at most gardening stores. Apply the fertilizer once or twice a month during the growing season, which is in spring and summer.
However, after repotting, wait at least six weeks before applying any fertilizer to avoid damaging the freshly repotted roots. Fertilizing isn’t necessary right after blooming either, especially if the plant enters a dormant phase. If your plant is thriving with plump, healthy leaves and strong roots, it’s a sign that the nutrient supply is adequate.
Blooming and Stem Care
The blooming of Phalaenopsis orchids is one of the most delightful aspects of growing them. When the flowers fade, there are a few things to keep in mind regarding stem care. In many cases, the flower spike dries up after blooming, but if it doesn’t, it’s worth waiting because the same spike can often rebloom.
If you notice that the flower spike is completely withering, trim it with a sharp knife at the base of the plant. Make sure the cutting surface is clean and sterilized to prevent pathogens from entering the plant. Pruning the spent flower spikes can encourage the plant to produce new shoots that may eventually bloom again.
Repotting: When and How to Repot Your Phalaenopsis Orchid
Phalaenopsis orchids don’t need frequent repotting, but it’s sometimes unavoidable, especially if the roots have outgrown the pot or if the potting medium is depleted. It’s generally recommended to repot every two years, but if the roots are spilling out of the pot, it may need to be done sooner.
Timing is also crucial when repotting. The best time is in the spring when the plant enters a growth phase and can recover more easily from the stress of repotting.
Steps for Repotting
To repot your orchid, you’ll first need a properly sized, transparent pot in which to place the plant. Sterilization is an important step, as it helps prevent pathogens from entering the plant through the cut surfaces.
The first step in repotting is to gently remove the plant from its old pot. Shake off any remaining old potting medium and carefully examine the roots. Remove any dead or rotten roots, and if necessary, trim the root system. If the plant has healthy, thick, fleshy roots, you can leave them intact.
Next, place the plant in the new pot, and gently fill the space between the roots with fresh orchid potting mix. Make sure the roots are well-distributed in the pot and not too tightly packed. After repotting, water the plant thoroughly to ensure the roots are well hydrated.

Two months after repotting, the orchid has regained its strength. New aerial roots have appeared, and the flower stem has also started growing vigorously. The high-quality orchid soil and regular watering have worked wonders. From now on, I’ll support the flower stem’s growth with orchid fertilizer. I’ll provide an update later.
Conclusion
Proper care for Phalaenopsis orchids involves providing the right light, water, and nutrients, as well as timely repotting, all of which contribute to the long-term health and blooming of the plant. By following the care tips outlined above, you can ensure that your orchids will continue to thrive and bring beauty to your home for many years.
Remember that Phalaenopsis orchids require special attention, but if you understand and respect their natural needs, they will reward you with their stunning blooms.
