Hydrangea prefers yin to yang. In spring, it is best to move to a semi-shady place outside for maintenance. Summer may need proper shade, and the light is getting weaker and weaker in autumn. It should be placed in a well-lit place to promote flower bud differentiation, and it can be placed in a sunny place indoors in winter.
