1. Soil and flower color

Hydrangea is a plant with strong vitality. It usually grows in loose, fertile, well-drained sandy soil. The pH value of the soil can directly determine the color of the hydrangea. If you like blue hydrangeas, you can use slightly acidic soil when cultivating them. If you like red hydrangeas, you can cultivate them in slightly alkaline soil.

2. Reasonable watering

When you grow hydrangeas, you must water them properly. This plant likes a humid environment, but is afraid of waterlogging. Especially after the rainy season, you must pay attention to controlling the number of waterings to prevent waterlogging in the flowerpots, otherwise the roots of the hydrangeas will rot, the leaves will turn yellow, and in severe cases, the hydrangeas will die. After entering winter, the growth rate of hydrangeas slows down. At this time, you should keep the pot soil dry and reduce the number of waterings.

Things to note when growing hydrangeas

1. Light exposure time

When growing hydrangeas, one aspect that people need to pay special attention to is the duration of light exposure, because hydrangea is a short-day plant. During normal cultivation, it is necessary to avoid direct sunlight and provide it with appropriate shade. About 60% sunlight is ideal, especially in the hot summer. Only proper shading can prolong the flowering period of hydrangeas.

2. Temperature

When growing hydrangeas, temperature is also an aspect that people need to pay special attention to. Hydrangeas will only grow rapidly when the outside temperature is between 18 and 28 degrees. After entering the flowering period, the temperature should be kept at around 20 degrees. After it blooms, the temperature can be controlled at around 16 degrees. This can effectively extend its flowering period. Moreover, if the temperature is too high during its flowering period, its flowers will fade, affecting its ornamental value.
