Our growers cultivate the best quality indoor hydrangeas, with care and love. With the proper care, a Magical indoor hydrangea will flower for 150 days. The most important thing is that hydrangeas regularly receive a little water to drink. Make sure that there is no water left in the pot, otherwise the plant will become dry and limp. To ensure a long and happy plant life you can also feed with extra pot plant food every other week. This gives the hydrangea a bit of extra strength.
