Hydrangea can be maintained indoors, but the indoor growth must be placed in a ventilated position. If the ventilation is poor, it will grow weak, it is also very bad for flowering.
Hydrangea is a short sunshine plant, so it doesn't need too long to be exposed to light every day, about 3 to 6 hours is enough. Moreover, it is a shade resistant plant, so it can grow in a slightly dark environment, but too much concealment will affect its flowering, so it should be placed in the light scattering place. In addition, it will grow in a large volume. If you want to maintain it indoors, you should have enough space and plant it in a flower pot of appropriate size.
