How to Cultivate Hydrangeas
Do you know about these? Here are some small experiences in green plant maintenance regarding how to cultivate hydrangeas and the detailed explanation of the maintenance points for hydrangeas. Below is a detailed introduction.
Hydrangeas are a type of native flower in China, formed by small flowers clustering together to create a flower ball that resembles a绣球 (hydrangea). They are excellent for decorating the environment. Hydrangeas prefer to grow in warm and humid places, with slightly acidic soil being the best. Let's learn about the maintenance methods for hydrangeas together.
1. Soil
Hydrangeas are suitable for growing in loose and fertile soil. They have a characteristic where the color of the flowers changes with the pH of the soil. Hydrangeas planted in alkaline soil are blue, while those in acidic soil are red.
2. Light
Hydrangeas enjoy diffused light and cannot tolerate direct sunlight. In full-sun environments, it is necessary to provide appropriate shading. Three to six hours of sunlight per day is sufficient to maintain normal plant growth.
3. Temperature
The optimal growth temperature for hydrangeas is between 18-28°C. In spring, the plants start to sprout, and when the temperature is at 20°C, the flower buds begin to differentiate. Note that the temperature in winter should not be lower than 5°C.
4. Fertilizing and Watering
Hydrangeas should not be fertilized with concentrated fertilizers. It is recommended to apply a dilute fertilizer every 15 days, and to stop fertilizing when the weather gets cold. During the cultivation process, keep the soil moist, watering every 3-5 days is usually enough.
5. Pruning
The more common hydrangeas on the market are Endless Summer and Large Flower Hydrangea. There is no special timing for pruning Endless Summer, while Large Flower Hydrangeas require pruning to be completed by the end of August. After that, the time begins for flower bud differentiation. If pruning is delayed, it is easy to cut off the flower buds, reducing the number of flowers and affecting the plant's ornamental value.
