How to Plant Hydrangea in a Container

Updated March 23, 2017

The hydrangea is a deciduous shrub that blooms in big, round balls of colour. Although the shrubs can get rather large, there are some varieties that will do well in a container. Look for the Annabelle, Nikko Blue, Veitchii or Alice varieties for best results. Growing hydrangeas in pots and containers is a little more difficult than growing them in the garden, but it can be done if you pay close attention to their needs.

Pour equal parts of potting soil and compost into a 16-inch-diameter pot. Fill the pot so that the crown of the plant will sit just under the surface of the soil when the pot is filled to within 1/4 inch of the top. Water the soil well, mixing it as you go to ensure that there are no dry spots.

Remove the hydrangea from the pot in which it currently sits and gently loosen the root-ball with your fingers.

Set the hydrangea in the pot, fanning out the roots. Use your gardening trowel or your hands to backfill with the planting mix, packing it down as you go to remove any air pockets.

Add a 3-inch layer of mulch, such as pine bark, around the base of the plant. Water until the soil is completely drenched.

Place the hydrangea where it will receive dappled sunlight. If it gets hot where you live, place the potted hydrangea in the shade. Water at least once a day, twice during hot weather.
