River Birch

Question

I was surprised to learn that a river birch could be grown in a container. I would like to know if the tree can stay outside or should it protected somehow during winter months. I live in western NY-Zone 5.

Answer 1

Treat plants in containers as though they are growing in one zone lower than your current zone. So, since you live in Zone 5, you will need to find a variety of river birch that survives in Zone 4 in order to grow it in containers outside year round where you live.
