Potted plants, as part of home decoration, can beautify the environment and cultivate one's temperament. During use, we often encounter some problems, such as spots on the leaves of potted plants. This not only affects the appearance of the plant but may also threaten its health. This article will provide a detailed analysis of the reasons for spots on potted plant leaves and the corresponding solutions, helping you easily deal with this common problem.
Reasons for spots on potted plant leaves1. Pathogen infection
Pathogen infection is one of the main reasons for spots on potted plant leaves. Common pathogens include fungi, bacteria, and viruses. When the environmental humidity is high and the temperature is suitable, pathogens can easily multiply, leading to leaf spots.
2. Pest damage
Pest damage is also an important factor in spots on potted plant leaves. Common pests include aphids, red spiders, and scale insects. These pests absorb nutrients from the plant, causing spots on the leaves.
3. Malnutrition
During plant growth, if there is a lack of essential nutrients, spots can also appear on the leaves. Insufficient elements like nitrogen, phosphorus, and potassium can cause spots on the leaves.
4. Insufficient lighting
Long-term exposure to阴暗 conditions or insufficient lighting can cause spots on potted plant leaves. This is because the plant cannot perform photosynthesis sufficiently, affecting growth.
5. Improper water management
Too much or too little watering can cause spots on potted plant leaves. Excessive watering can lead to root hypoxia, affecting the plant's nutrient absorption; too little watering can cause the leaves to lose water, resulting in spots.
Solutions for spots on potted plant leaves1. Pathogen infection
After spots on the leaves are found, first, remove the diseased leaves to prevent the spread of the disease. You can use a 50% carbendazim wettable powder 800x solution or a 75% chlorothalonil wettable powder 800x solution for foliar application. Apply every 7-10 days, for a total of 2-3 times.
2. Pest damage
After detecting pests, insecticides can be used for control, such as 20% imidacloprid emulsion 2000x solution or 40% dimethoate emulsion 1000x solution. When spraying, make sure to spray evenly, ensuring both sides of the leaves are covered.
3. Malnutrition
For spots caused by malnutrition, a compound fertilizer or foliar fertilizer can be applied. During the vigorous growth period, apply every 15 days to supplement the nutrients needed by the plant.
4. Insufficient lighting
Move the potted plant to a place with sufficient lighting to ensure the plant can receive adequate sunlight. If space is limited, artificial lighting can be provided using a plant growth lamp.
5. Water management
Arrange the watering frequency according to the growth habits of the potted plant. Generally, keep the soil slightly moist, avoiding excessive or insufficient watering.
