Hydrangea cultivation methods and precautions

Hydrangea has bright colors and a flower shape similar to hydrangea, which is particularly beautiful. It is the favorite ornamental flower in life. People usually like to make it into potted plants and grow it at home. However, hydrangea is relatively delicate and difficult to grow. Before growing it, people must learn more about its cultivation methods and precautions during the cultivation period, otherwise it is difficult to grow hydrangea well. The following is my detailed introduction to its cultivation methods and precautions. Friends who like this plant can focus on it.

Farming methods

Hydrangea likes a warm and humid semi-shady environment. It is afraid of drought and cold, and is not cold-resistant. It cannot be placed outdoors in winter, otherwise it will wither and die. Hydrangea should be cultivated in fertile, moist, well-drained, slightly acidic soil. However, the pH of the soil has a significant effect on the color of hydrangea. Hydrangea grown in slightly acidic soil blooms blue flowers, while hydrangea grown in alkaline soil blooms red flowers.

Precautions

1. Temperature regulation

When growing hydrangeas, you must pay attention to temperature regulation. This plant grows best when the outside temperature is between 18 and 25 degrees Celsius, but the ambient temperature of hydrangeas in the north cannot be lower than 5 degrees Celsius in winter. After it enters the flower bud differentiation period, the ambient temperature must be between 5 and 7 degrees Celsius. When it is about to bloom, it should be moved to a temperature of about 20 degrees Celsius. After flowering, keep the ambient temperature at around 16 degrees Celsius to effectively extend the flowering period.

2. Fertilizer and water management

It is also very important to manage the fertilizer and water of hydrangeas at ordinary times. After the hydrangeas enter the budding state in spring, they must be watered sufficiently and the leaves must not wither. June to July each year is the flowering period of hydrangeas. At this time, it is necessary to ensure sufficient supply of fertilizer and water. Not only should they be watered once a day, but they should also be fertilized once every half a month. Fertilizers can be selected, thin liquid cake fertilizers, and a small amount of phosphorus fertilizer can be applied before it blooms. This will make its flowering period longer and the flowers more colorful.
