Root collar vs. root crown
We are preparing to plant two potted citrus in the ground as soon as we can. I have seen recommendations to plant so that the root collar is above the soil line, and the root crown is just below the soil line. I am having trouble finding a description or photos to help me recognize and distinguish the two. How can I tell the difference?
I'm sorry if this has been asked and answered before... perhaps some newbies could benefit from a new post on this subject alone.
