1、 Can I

Hydrangea can be maintained indoors, but indoor growth must be placed in a ventilated place. If the ventilation is poor, it will grow weakly and be very unfavorable to flowering

2、 Conservation environment

Hydrangea is a plant with short sunshine, so it doesn't need to be exposed to light for too long every day. About 3 to 6 hours is enough. Moreover, it is a shade tolerant plant, so it can grow in a slightly dark environment, but too hidden will affect its flowering, so it should be placed in a bright scattered light. In addition, it should be noted that it grows in a large volume during its growth. If it is maintained indoors, it should have enough space and be planted in a flower pot of appropriate size
