Hydrangeas are very beautiful ornamental plants, but when watering them in the summer, if you don't pay attention to the watering method and frequency, it can lead to the death of the plant. We need to understand the scientific watering methods to help hydrangeas grow strong and bloom beautifully.
Understanding the growth habits of hydrangeas
Hydrangeas are moisture-loving plants that thrive in humid environments but do not like overly moist soil. We need to pay special attention when watering to avoid making the soil too wet.
Watering cycle in summer
Summer temperatures are high, and water evaporates quickly, so we need to increase the frequency of watering. Generally, in hot and dry weather, we need to water hydrangeas once a week, keeping the soil moist each time.
Determining the watering time
Morning and evening are the most suitable times to water hydrangeas. Because the temperature is lower during these periods, it reduces evaporation. At noon, the temperature is higher, and water evaporates easily, so we should not water hydrangeas at this time.
Pay attention to water quality
When watering hydrangeas, the quality of the water is also very important. It is best to use soft water or rainwater for irrigation, as hard water or water with high salt content can damage the soil structure and affect plant growth.
The amount of water
When watering hydrangeas, we need to pay attention to the amount of water. Generally, the amount of water should be about 10 cm each time, but the specific amount should also be determined based on the size of the plant and the humidity of the soil.
Watering methods
The watering method is also very important. We should pour the water slowly around the plant, rather than spraying it directly onto the plant. This can prevent water droplets from falling directly on the leaves and causing damage.
Avoid waterlogging
Hydrangeas do not like waterlogging. If the soil is too waterlogged, it can lead to plant diseases. After watering, we need to promptly drain any excess water.
Watering time
The time of watering hydrangeas is also very important. Generally, it is best to water in the morning or evening, and avoid watering the plant when it is directly exposed to the sun.
Soil quality
Hydrangeas require good quality soil that is rich in organic matter and nutrients. If the soil quality is poor, it will affect the growth of the plant, and the soil needs to be replaced or fertilized in a timely manner.
The impact of climate
Climate also affects the growth of hydrangeas. In hot and dry weather, we need to increase the frequency of watering. During the rainy season, we need to reduce the number of waterings to avoid the soil becoming too wet.
Appropriate fertilization
Appropriate fertilization is also helpful for the growth of hydrangeas. We can fertilize in spring and autumn to ensure the plant has enough nutrients to grow.
Avoid leaf irrigation
When watering in the summer, we need to avoid leaf irrigation. Because leaf irrigation can easily lead to plant diseases and also cause obstacles to photosynthesis.
Prune in a timely manner
Timely pruning is also an important part of hydrangea growth. Pruning can promote branching and renewal of the plant, making it more lush.
Take pest control measures
In the summer, hydrangeas are susceptible to pests, so we need to take pest control measures. Biological or chemical control methods can be used to protect the plant.
Through the above introduction, we can understand how to water hydrangeas scientifically to keep them evergreen and beautiful in the summer. The key is to pay attention to the watering method and frequency, and avoid the soil being too wet or too dry. At the same time, it is also necessary to pay attention to other aspects of management, such as fertilization, pruning, and pest control, to make the hydrangeas grow more lush.
