Methods to prevent plants from getting "air-conditioner disease" during extreme heat
The article discusses common knowledge about plant cultivation, specifically methods to prevent plants from suffering "air-conditioner disease" during extreme heat, and invites readers to learn more.
Recently, Beijing has entered a period of high temperatures and extreme heat. Not only are people suffering, but some potted plants, such as orchids, pothos, and even the more expensive Taxus chinensis, seem unable to withstand the high temperatures. Some are shedding leaves, while others are withering, and the cause is unknown. After careful observation, it turns out that plants are also susceptible to heat, but they can also get "air-conditioner disease" in air-conditioned rooms. Below are several methods to prevent air-conditioner disease in plants.
Method One: Avoid placing potted plants in air-conditioned rooms. Due to the strong sunlight in summer, some people move their potted plants from the balcony inside the house. If the air conditioner is turned on, it will create a "temperature difference." Therefore, potted plants should not be placed in air-conditioned rooms, and if they must be, they should be kept away from the air conditioner outlet, as the dehumidifying function of the air conditioner can cause the plant leaves to lose moisture and wither.
Method Two: Water when the soil is dry and moist. It is best to water in the evening. More people have problems due to incorrect watering. The most important aspect of caring for potted plants, especially in summer, is watering. Timing and temperature are key. The timing is to water when the soil is "dry and moist," meaning to water only when it is truly dry. How to determine "dry"? It is usually by looking at the surface soil, but sometimes it is not conclusive and other methods are needed, such as tapping the bottom of the pot with a finger. If it makes a "hollow sound," the soil below is also dry; if it makes a "dull sound," the soil has higher moisture content. Also, observe the new tender leaves of the plant because once they lack water, these leaves will show signs of fatigue or even wilt. Moreover, watering during the hot season should be done in the evening, as after a day of evaporation, it is necessary to replenish water at night. The water used should be prepared in advance and brought to a temperature close to that of the soil in the pot before watering. However, most people water plants with water directly from the tap, which can cause a "temperature difference" due to the lower water temperature, leading the plant to "catch a cold" and get sick, resulting in leaf shedding and withering.
Method Three: Place flowers on the north-facing balcony and avoid frequent moving. In summer, potted plants should be placed on a north-facing balcony or windowsill. If placed on a south-facing balcony, there should be a shading facility, and proper ventilation should be maintained. Some people move their plants inside when the sun is strong and back outside when it is not or in the morning and evening, but this is not good. Plants have a phototropic nature (sunflowers are a typical example), and frequent moving can make it difficult for plants to adapt to constant adjustments in light exposure, leading to a kind of "disorder" and resulting in the plant "getting sick."
Method Four: Eggshells, tea leaves, and rice washing water do not have fertilizing effects. Many people have misunderstandings about fertilizing when growing flowers. For example, putting crushed eggshells or used tea leaves in the pot has no fertilizing effect and can even cause mold that affects the normal growth of the plant. Some people also like to use rice washing water or "fertilizer water" from washing milk bottles to water their plants, but apart from a few trace elements, this "fertilizer water" has no fertilizing effect because it has not been fully fermented and can even attract ants and earthworms. Even with fermented flower fertilizer bought from a store, it should not be used excessively in summer. If citizens buy a potted landscape or plant, they can make an agreement with the seller at the time of purchase for "after-sales care" to help the potted plant survive the summer.
