Planting Iris?

I live in N. Ontario Canada and I just recieved a bunch od bearded iris from a friend. I have them all in...just before our first frost. I planted the rizomes just about an inch below the surface of the soil. Is that deep enough in such a cold climate or should I mulch them for the winter?


These were a gift and I don't want to loose them.


Thanks!

I would cover them with some mulch, like bark or hay, another inch or two.. then when things start to defrost you can rake that away. Iris are pretty hardy they should start blooming in May or June. You can even put some in a pot they should grow inside but you will have to let them rest until the next fall if you want to put them in the ground later on..
Reply:Iris should not be planted below the surface. They should have some of the thizome at the surface, or slightly above. The roots should be buried. You can leave them as they are, and see if they come up in the spring. Mine all sit just at the surface, and I am in zone 5.
Reply:Mulch them, they should have gone down below the frost line.
