Why cut off all the leaves? Benefits of cutting all the leaves: In the field of gardening, there is a seemingly "cruel" pruning method-cutting all the leaves may sound unbelievable, but in fact, this method has been widely used in the horticulture world. Why cut all the leaves? What are the unexpected benefits of doing so? Let's solve this mystery. Why cut off all the leaves?
1. Promote plant growth When plants undergo photosynthesis, they need to absorb sunlight, water and nutrients through their leaves. If all the leaves are cut off, the plant will feel the "crisis", thereby accelerating the growth rate so that new leaves can grow as soon as possible. In this way, the plant can get more sunshine and nutrients in a short period of time, thereby increasing the growth rate.
2. Prevention of pests and diseases Leaves are the most vulnerable parts of the plant that are attacked by pests and diseases during plant growth. If all the leaves are cut off, the occurrence of pests and diseases can be reduced, and the cut off leaves can reduce the habitat of pests and diseases; after new leaves grow, It has stronger resistance to pests and diseases.
3. Improve the ornamental value Some plants will become more prominent after the leaves are fully cut, thereby improving the ornamental value. For roses, peonies and other flowers, the beauty of the flowers will be further improved after the leaves are fully cut. Benefits of cutting all leaves 1. Improve photosynthesis efficiency After cutting off some leaves, the photosynthesis area of the plant will be relatively reduced, but the photosynthesis efficiency will increase. This is because after cutting off some leaves, the plant can be more concentrated. Use sunlight, water and nutrients to improve photosynthesis efficiency.
2. Accelerate plant metabolism After the leaves are completely cut, the metabolism rate of the plant will accelerate. This is because in order to grow new leaves as soon as possible, the plant will accelerate the circulation of nutrients in the body, thereby increasing the metabolism rate.
3. Reduce water evaporation After cutting off some leaves, the water evaporation rate of the plant will decrease. This is because the leaves are the main way for the plant to evaporate water. After cutting off some leaves, the evaporation of water can be reduced, thereby reducing the plant's water demand. Notes 1. Choose the right time to cut all the leaves. It is best to choose a period when the plant is growing vigorously, such as spring or autumn. The plant has strong resistance to stress and is easier to recover after the leaves are cut.
2. Control the degree of pruning When cutting off the leaves, pay attention to the degree of pruning. Generally speaking, the area of the leaves cut off should not exceed 1/3 of the total leaf area of the plant.
3. Pay attention to pruning methods. Try to use sharp scissors when pruning to avoid damaging the plants. Pay attention to the wound management after pruning to prevent the invasion of bacteria.
Although cutting all the leaves may sound cruel, it is actually a very practical gardening technique. Through this method, you can promote plant growth, prevent pests and diseases, improve ornamental value, and bring a series of unexpected benefits. In the actual operation process, you also need to pay attention to relevant matters to ensure the healthy growth of plants. I hope this article can provide a useful reference for your practice in gardening.
