Plant your hydrangea outdoors
Hydrangea plants are hardy and disease-resistant for the most part, though they can be infected with mildew if planted in areas that are shady and humid,. For best conditions, plant them in a sunny spot and offer plenty of water. The hues can change depending on the type of soil the flowering plants are put in. For example, pink hydrangeas will turn blue when planted in acidic soil, while red varieties can be enhanced by adding a layer of limestone or chalk to the soil around it during the winter.
