In the natural growth and development of flowers and trees, wilting can occur due to various factors, such as environmental stress or internal issues, which may hinder their normal development. In severe cases, this can lead to the death of plants, so it's crucial to take timely action to address the problem.
First, drought or flooding caused by prolonged dry periods or insufficient watering can result in wilting starting from the top of the plant, with the bark of branches shrinking or even leading to plant death. To help these plants recover, it’s recommended to mist the leaves and the surrounding area to maintain high humidity. Avoid using cold water for irrigation during hot weather, as this can shock the roots and worsen the condition.
Second, when the soil becomes overly saturated, root respiration is impaired, preventing the branches and leaves from receiving enough water, which can cause wilting or even death. To prevent further damage, avoid direct sunlight and strong winds, and prune some of the tender leaves. For garden-planted trees, loosen the soil around them. If they are potted, remove one-third of the wet soil and replace it with dry soil, then water thoroughly to flush out excess fertilizer. Apply a diluted liquid fertilizer every three days, and after 10 days, most plants should begin to recover.
Third, excessive fertilizer concentration in the soil can cause a reverse osmosis effect, where water from the plant moves into the soil, damaging the roots—commonly known as "burning." To treat this, water the soil to dilute the fertilizer and drain any excess. For potted plants, remove the top layer of soil, rinse the pot with water, and add fresh soil on top. Shade the affected plants and mist them regularly. After 10 to 20 days, recovery is usually possible.
Fourth, if insect infestations cause serious damage to the main trunk or branches, wilting or death can occur. Wilting caused by pests is often irreversible. For valuable plants, pruning or grafting might be necessary to save them.
Fifth, new shoots, especially spring growth, are vulnerable to wilting when exposed to intense light and wind—especially dry winds. Providing shade, protection from wind, and misting the leaves can help prevent moisture loss and keep the shoots healthy.
Sixth, if flowers or trees are placed in areas with strong light and high temperatures, their leaves may wilt, turn yellow, or fall off. It's best to move them to a cool, moist, and well-ventilated location to help them recover.
Lastly, in colder regions, sudden drops in nighttime temperatures, especially below 10°C, can affect tropical or southern plants like hibiscus, jasmine, and azaleas. They may appear wilted in the morning but may recover at noon when the temperature rises. Although short-term cold exposure isn’t always fatal, it’s important to protect them from extreme temperature changes.
