Hydrangea, also known as eight immortal flowers, has become the first choice for many families and garden greening due to its beautiful flower shape and colorful colors. Many flower friends find that the leaves of hydrangea often appear white, which not only affects its appearance but may also affect its growth. This article will reveal the secret of white leaves of hydrangea and share some practical maintenance methods.
Secret of white leaves of hydrangea1. Disease cause
The white spots on the leaves of hydrangea may be caused by pest and disease invasion. Common diseases include powdery mildew, leaf spot disease, etc. These diseases can cause white spots, spots or patches on the leaves, and in severe cases, even lead to leaf withering and falling off.
2. Insufficient water
Hydrangea prefers a humid environment. If the soil is too dry, white spots will appear on the leaves. This is because insufficient water causes the leaf cells to lose water, resulting in white spots.
3. Insufficient light
Hydrangea requires sufficient sunlight. If it is in a dark environment for a long time, white spots will also appear on the leaves. This is because insufficient light weakens photosynthesis, preventing the leaves from normal nutrient metabolism.
4. Soil problems
Soil compaction, excessive acidity, or lack of nutrient elements can also cause white spots on the leaves of hydrangea. This is because soil problems affect the plant's absorption of water and nutrients, thus affecting leaf growth.
Maintenance methods of hydrangea1. Reasonable watering
Hydrangea prefers a humid environment but dislikes waterlogging. In the growing season, keep the soil moist and avoid drought. In high summer temperatures, you can appropriately increase the watering frequency. In winter, when the temperature is low, you should reduce watering and keep the soil slightly moist.
2. Appropriate fertilization
Hydrangea has a high demand for fertilizer. In the growing season, compound fertilizer or organic fertilizer can be applied every 15-20 days to promote plant growth. After fertilization, water in time to prevent fertilizer from burning the roots.
3. Keep ventilation
Hydrangea prefers a ventilated environment. The air around the plant should be kept flowing to prevent the breeding of diseases. In high summer temperatures, you can appropriately shade to reduce direct sunlight.
4. Prevent and control pests and diseases
Regularly check the hydrangea plants. Once pests and diseases are found, take measures in time. Pesticides can be used for prevention and control, and plant maintenance should be strengthened to improve resistance.
5. Pay attention to light
Hydrangea requires sufficient sunlight but dislikes direct sunlight. In the growing season, the plant can be placed in a semi-shaded place to avoid direct sunlight. In winter, you can appropriately increase the light time to promote plant growth.
