How to plant a potted hydrangea outside

A pretty pot containing a hydrangea makes a simple and stunning gift. Potted hydrangeas are readily available at florists and grocery stores for far less than the price of those at nurseries and home improvement centres. These small potted plants are not generally intended to be grown in the ground. However, with the proper care, you can get months of outdoor enjoyment from them.

Use proper care for your hydrangea before moving it outside. Keep the hydrangea in the coolest room of the house. Place it near a window where it will receive ample sunlight. Keep the soil moist, but not wet.

Move the hydrangea outside in early spring, to give it time to get used to being outdoors. Remove the plant, along with the original soil, and place it in a terra cotta pot. Set it outside in a sunny spot. Water and fertilise the hydrangea in the pot for a few weeks.

Choose a well-drained location outside that receives sun in the morning and shade in the afternoon. Dig a hole in the soil approximately the same size as the pot the hydrangea is in. Remove the plant and the soil from the pot and place in the hole. The plant should not be any deeper in the new hole than it was in the pot.


An interesting fact about hydrangeas is that (with the exception of white hydrangeas), the colour of the blossoms change depending on the acidity of the soil. Blue hydrangeas need aluminium in the soil, but pink hydrangeas require soil without aluminium. Soil that is low in acid is good for pink hydrangeas. You can add lime to the soil to make it more acidic. For blue hydrangeas, a low-acid soil is necessary. A simple way to add acid to the soil is by adding natural materials such as grass clippings or coffee grounds. When shopping for commercial fertiliser, look for one marked 25-5-30.


Make sure not to water the plant too much while indoors.
