Causes of Split Leaves on Phalaenopsis Orchids and How to Solve Them

Phalaenopsis orchids attract countless flower lovers with their elegant, dancing blooms. Yet this beautiful fairy among flowers has a "delicate" side, namely the problem of split leaves often encountered during care. When faced with this problem, how should flower lovers solve it?

For growers, the last thing they want to see is surely flowers withering or leaves splitting, because besides ruining the plant's beauty, it also seems to hint that the plant is not far from decline, which is distressing to look at. When encountering such problems, we first need to know that leaves can only grow vigorously largely by relying on a healthy root system.

So finding split leaves is equivalent to being told that the root condition is not ideal. Among the possible causes, the air environment may be too dry with insufficient humidity, which naturally makes the leaves prone to drying and cracking. It is also possible that something went wrong with fertilizing, using high-concentration fertilizer that scorched the leaves, ultimately causing them to split. Only after finding the real cause can the right remedy help the plant return to a healthy path.

Among the many factors that cause leaves to split, the one that most people get wrong is "dryness." Once there is a sudden temperature change, the relative humidity of the air becomes extremely low. At this time, the leaves are constantly losing water, which then causes the leaves to dehydrate and split. The solution, of course, is to raise the humidity around the pot, especially in the crisp autumn, when you need to spray water mist on the leaves and around the plant to increase air humidity. In winter, the plant needs a slightly drier state, so avoid excessive watering and spraying.

Besides increasing humidity, a stable indoor temperature is also a kind of protection for Phalaenopsis orchids. Their most suitable temperature range is between 18°C and 30°C. As long as the temperature can be kept within this range, its root system will be relatively healthy and steadily absorb nutrients. If the temperature deviates too much, such as exceeding 30°C, the plant will directly go dormant and stop growing.

At this point, it is recommended to buy a sunshade, or move the plant to a relatively cooler environment during the midday sun. In the cold winter, when the temperature drops to 10°C, move the plant promptly to a warm indoor spot to help it withstand the severe cold, and at night put a black plastic bag over it to protect it from the wind.
