Many people say that Phalaenopsis orchids are delicate and hard to care for, but in fact, they can thrive anywhere! However, growing them in the North and the South is quite different—just like how it's tough for people from the Northeast to adapt to Hainan's humid heat, or for people from Guangdong to get used to the dry cold of the North, Phalaenopsis orchids must also adapt to their local environment.
Many flower lovers in the South can simply place their Phalaenopsis orchids by the window and watch them bloom, while Northern growers often encounter problems like root rot and dry tips. The core issues are twofold: different environments and different growing mediums. The biggest difference between growing orchids in the North and South is the environment! The South is humid year-round, with air humidity often above 60%, and winters are not very cold. Phalaenopsis orchids are like being in a "natural greenhouse" and don’t have to worry much about dryness. But in the North, winters come with heating, which makes the indoor air dry and hot, often with humidity below 30%. Phalaenopsis leaves are prone to wrinkling, and the roots can easily become brittle. Although the summer is slightly more humid, it’s still nowhere near as humid as the South. Therefore, growing orchids in the North requires addressing the "dryness" issue, while in the South, you need to prevent "dampness." This is the first step you must differentiate.
The most common dilemma for Northern growers is: Should I use sphagnum moss or bark? Let’s first understand the two growing mediums. Sphagnum moss has a strong water retention ability. Once it’s saturated, it slowly releases moisture and wraps around the Phalaenopsis roots, preventing them from drying out. However, it has its drawbacks. If watering is not controlled properly, the moss can become compacted in the pot and may not allow enough airflow, which can lead to root rot. But for Northern regions, sphagnum moss’s ability to retain moisture can help counter the dry air, especially when heating is on in the winter. It helps keep the humidity in the growing medium for longer, reducing the need for daily watering. When using sphagnum moss, make sure to choose clean, dry moss. After soaking, squeeze out excess water without making it too dry or too wet, and wrap it around the roots before placing it in a transparent pot. This allows you to monitor the root condition and spot any rot early.
As for bark, it has good aeration, with large gaps that allow excess water to drain quickly, preventing root suffocation. The downside is that it has poor water retention. In the dry Northern climate, water evaporates from the bark very quickly, meaning the growing medium may dry out within just a few days after watering. Phalaenopsis roots may become "thirsty," and the leaves will wilt. If you decide to use bark, you need to observe closely and water when the surface of the growing medium appears dry. Additionally, spraying water around the pot to increase air humidity is essential. Otherwise, even though bark is highly breathable, the roots won’t have enough water to thrive.
When growing Phalaenopsis in the North, whether to choose sphagnum moss or bark depends on your usual care habits. If you tend to forget watering or travel frequently, sphagnum moss is a good choice due to its strong water retention—Phalaenopsis orchids won’t wilt immediately even if you forget to water. If you enjoy watering and worry about the plant drying out, bark is the better option, as it’s more breathable and reduces the risk of root rot even if you water a little too much. Regardless of which medium you choose, always use a transparent pot. Phalaenopsis roots need some light, and a transparent pot allows you to monitor the root condition, making it more practical than opaque pots.
For Northern orchid care, don’t just focus on the growing medium—humidity and temperature also need to be managed. In winter, avoid placing the Phalaenopsis near the heater. Keep it a bit farther away, and consider using a humidifier or placing a water dish nearby to raise the humidity. In summer, don’t let the plant be exposed to direct sunlight; place it in a location with indirect light. Once you understand the differences between the North and South environments and choose the right growing medium, you can grow Phalaenopsis orchids in the North that bloom beautifully year after year, just as well as in the South!
