How to protect Hydrangea plants that grew from shoots

Question

How can I protect my Hydrangea plants that I grew from shoots this summer? I live in Southern Ontario, Canada. They have been outside all summer. I wish to protect them from a Canadian winter for spring planting.

Answer 1

I recommend continuing to grow the plants outdoors and water until they go dormant and drop their leaves.
Then you can move them to a garage or a very sheltered location. You can check the soil throughout the winter to make sure it is not completely dried out, add a bit of moisture if it is needed.
Snow cover is an excellent insulator.
In the spring after danger of frost has passed bring them back outdoors.
