How to Prevent "Air-Conditioning Disease" in Plants in Summer

Plants can get sick too. In the hot summer, if your plants stay in an air-conditioned room for a long time without ventilation, they can also come down with "air-conditioning disease." Plants like pothos (Epipremnum aureum) and some rather valuable Chinese yews (Taxus chinensis) are very afraid of heat, and under high temperatures their leaves will wilt and so on. But if you keep them in an air-conditioned room for a long time, they will also get air-conditioning disease. The editor has put together four methods for preventing air-conditioning disease in plants; friends who need them can come and learn.

Method One

Potted plants should be exposed to air conditioning as little as possible. Because the summer sun is strong, some people move potted plants that were originally on the balcony back indoors. If the air conditioner is then turned on at home, a "temperature difference" will occur. So potted plants should as much as possible not be placed in air-conditioned rooms, and even if they are, they should be kept away from the air-conditioning vent, because air conditioners have a dehumidifying function that will cause the moisture on plant leaves to evaporate, making them wither.

Method Two

Water by the "dry-wet" rule, and preferably water in the evening. For household potted plants, the most important thing to master is watering, especially in summer; watering requires grasping both timing and temperature. The so-called timing means "water when dry, stop when wet," that is, water only when truly dry. How do you judge "dry"? Generally you look at the surface soil, but sometimes that is still not enough to be sure, so you have to supplement it with other methods, such as tapping the lower part of the flowerpot lightly with your finger. If it gives a "hollow sound," then the soil below is dry too; if it gives a "muffled sound," then it shows the soil has a relatively high water content. Also, observe the plant's newly grown tender buds and leaves, because once there is a water shortage, these buds and leaves will be the first to appear limp or even withered. Furthermore, watering in hot seasons also has its finer points; it is best to water in the evening, because after a whole day of evaporation during the day, the plant needs timely replenishment at night. The water used should be prepared in advance and left until it is close to the temperature of the soil in the flowerpot before watering. But most people draw water from the tap on the spot to water. In that case, the "temperature difference" caused by the low water temperature will make the plant "catch a cold" and get sick, which in turn causes it to drop leaves and wither.

Pothos

Method Three

In summer, put flowers on a north-facing balcony and do not move them frequently. In summer, potted plants should be placed on a north-facing balcony or windowsill. If they are placed on a south-facing balcony, there should be shading facilities, and ventilation should also be maintained. Some people move them back indoors when the sun comes out, and move them to the balcony again when the sun is not strong or in the morning and evening. Actually, this is not good, because plants all have phototropism (the most typical being the sunflower), and frequent moving makes it hard for plants to adapt to the constantly adjusting light-receiving surface, thus producing a certain kind of "disorder," which in turn causes them to "get sick."

Method Four

Eggshells, tea leaves, and rice-washing water have no fertilizing effect. Many citizens also have misunderstandings about fertilizing when growing flowers. For example, pouring crushed eggshells, used tea leaves, and so on into flowerpots. Actually, these things have no fertilizing effect at all; instead, they will grow mold and affect the normal growth of plants. Some people also like to use rice-washing water or the "nutrient water" from rinsing milk bottles to water flowers, but apart from a very small amount of trace elements in them, these "nutrient waters" have not undergone full fermentation, so they have no fertilizing effect on plants; instead, they will attract ants and earthworms. Even for fermented flower fertilizer bought from flower shops, do not apply too much in summer. If flower lovers buy bonsai or potted flowers, they can agree with the seller at the time of purchase to help the potted plants get through the summer safely through "after-sales care."

Keeping plants at home is not just about remembering to water regularly. If you want your plants to grow well, you still need to pay more attention to their growth conditions during ordinary care. In the hot summer, some plants cannot tolerate high temperatures, so moving them to a cool, ventilated place is very necessary, but you should also be careful not to let your plants come down with air-conditioning disease.

How to Prevent Plants from Getting "Air-Conditioning Disease"

China Landscape Web, August 8 news: In the severe heat, not only do people feel uncomfortable from the heat, but some potted plants grown by flower lovers, such as orchids, pothos, and even the rather valuable Chinese yew (Taxus chinensis), also seem unable to withstand the high temperatures. Some drop leaves and some wither, and no one knows why. After careful observation, it was found that plants are also afraid of heat, but in air-conditioned rooms they can also get "air-conditioning disease." Below are several methods to prevent "air-conditioning disease" in plants.

Method One: Potted plants should be exposed to air conditioning as little as possible. Because the summer sun is strong, some people move potted plants that were originally on the balcony back indoors. If the air conditioner is then turned on at home, a "temperature difference" will occur. So potted plants should as much as possible not be placed in air-conditioned rooms, and even if they are, they should be kept away from the air-conditioning vent, because air conditioners have a dehumidifying function that will cause the moisture on plant leaves to evaporate, making them wither.

If they are placed on a south-facing balcony, there should be shading facilities, and ventilation should also be maintained. Some people move them back indoors when the sun comes out, and move them to the balcony again when the sun is not strong or in the morning and evening. Actually, this is not good, because plants all have phototropism (the most typical being the sunflower), and frequent moving makes it hard for plants to adapt to the constantly adjusting light-receiving surface, thus producing a certain kind of "disorder," which in turn causes them to "get sick."

Don't Let Indoor Plants Also Get "Air-Conditioning Disease" in Summer

These past two days, Nanjing has entered a period of severe heat. Not only do people feel uncomfortable from the heat, but some citizens' potted plants, such as orchids, pothos, and even the rather valuable Chinese yew (Taxus chinensis), also seem unable to withstand the high temperatures. Some drop leaves and some wither, and no one knows why. Yesterday morning, for this reason, the reporter made a special visit to Mr. Pan Yulong, owner of the "Wuyuan" bonsai garden in Nanjing and standing director of the China Bonsai Artists Association, asking him to explain the reasons and "offer tips" to citizens.

Tip One

Potted plants should be exposed to air conditioning as little as possible

Regarding the situations some citizens encountered, Mr. Pan explained that because the summer sun is strong, some people move potted plants that were originally on the balcony back indoors. If the air conditioner is then turned on at home, a "temperature difference" will occur. So potted plants should as much as possible not be placed in air-conditioned rooms, and even if they are, they should be kept away from the air-conditioning vent, because air conditioners have a dehumidifying function that will cause the moisture on plant leaves to evaporate, making them wither.

Tip Two

Water by the "dry-wet" rule, and preferably water in the evening

More people's problems are caused by improper watering. In fact, for household potted plants, the most important thing to master is watering, especially in summer; watering requires grasping both timing and temperature. The so-called timing means "water when dry, stop when wet," that is, water only when truly dry. How do you judge "dry"? Generally you look at the surface soil, but sometimes that is still not enough to be sure, so you have to supplement it with other methods, such as tapping the lower part of the flowerpot lightly with your finger. If it gives a "hollow sound," then the soil below is dry too; if it gives a "muffled sound," then it shows the soil has a relatively high water content. Also, observe the plant's newly grown tender buds and leaves, because once there is a water shortage, these buds and leaves will be the first to appear limp or even withered.

Furthermore, watering in hot seasons also has its finer points; it is best to water in the evening, because after a whole day of evaporation during the day, the plant needs timely replenishment at night. The water used should be prepared in advance and left until it is close to the temperature of the soil in the flowerpot before watering. But most people draw water from the tap on the spot to water. In that case, the "temperature difference" caused by the low water temperature will make the plant "catch a cold" and get sick, which in turn causes it to drop leaves and wither.

Tip Three

In summer, put flowers on a north-facing balcony and do not move them frequently

Mr. Pan also "offered a tip," saying that in summer, potted plants should be placed on a north-facing balcony or windowsill. If they are placed on a south-facing balcony, there should be shading facilities, and ventilation should also be maintained.

Some people move them back indoors when the sun comes out, and move them to the balcony again when the sun is not strong or in the morning and evening. Actually, this is not good, because plants all have phototropism (the most typical being the sunflower), and frequent moving makes it hard for plants to adapt to the constantly adjusting light-receiving surface, thus producing a certain kind of "disorder," which in turn causes them to "get sick."

Tip Four

Many citizens also have misunderstandings about fertilizing when growing flowers. For example, pouring crushed eggshells, used tea leaves, and so on into flowerpots. Actually, these things have no fertilizing effect at all; instead, they will grow mold and affect the normal growth of plants. Some people also like to use rice-washing water or the "nutrient water" from rinsing milk bottles to water flowers, but apart from a very small amount of trace elements in them, these "nutrient waters" have not undergone full fermentation, so they have no fertilizing effect on plants; instead, they will attract ants and earthworms.
