See full answer to your question here. Consequently, are hydrangeas hard to care for?
Most hydrangeas thrive in rich, porous, somewhat moist soils. Add compost to enrich poor soil. They prefer full sun in the morning, with some afternoon shade; however, many will grow and bloom in partial shade. After water is drained, fill the rest of the hole with soil.
Subsequently, question is, how long will hydrangeas last? about two to three days
Correspondingly, can potted hydrangeas come back to life?
Although you can transplant these hydrangeas outdoors after they stop blooming, it's also possible to force them into bloom a second time as a potted plant. Reblooming hydrangeas requires proper pruning and care, along with a dormant period, to produce attractive flowers.
How do you keep hydrangeas alive outside?
Most varieties thrive in full sun to part shade, as long as they are planted in moist, rich soil. Water deeply once a week, and maybe more, if the weather is particularly hot or dry. Hydrangea fertilization needs vary greatly, depending on your intended bloom color.
