Should I pinch the top of my one apricot seedling stalk to encourage it to branch out? I started an apricot tree from a seed, and it is now four months old and only has one straight stalk with opposite leaves growing from this stalk. This stalk is now about 10 inches tall and I just transplanted it into a larger pot. Since I live in the Midwest with harsh winters, I will have to keep it growing in a pot for quite some time. I envision this stalk reaching the ceiling one day soon, and I need to find a method that will encourage this seedling to develop lateral branching. Thank you.
