Are my bleeding hearts safe in a container outside over winter if placed next to house

Question

My bleeding hearts are planted in a container and am wondering about surviving the winter in the container not sure what I need to do with them for the winter. I know they do good in ground but not sure about the container if you can let me know thanks

Answer 1

You may need to add some extra insulation to the pot along with adding 6 inches of mulch to the top of the pot.

A garden center will have container insulation wraps available in different sizes.
