Ginkgo root pruning question
I planted 2 ginkgo trees, variety called Philadelphia, a couple years ago in my back yard. They are doing well. Both of them have thrown up large shoots from their base, from the roots just below the soil, right beside the main leader. These shoots have grown to be very tall, almost as tall as the main leader. They look nice and give the trees a multi trunk look.
The main leader on one of the trees has always been unattractively twisted and crooked at the top, and weak which causes it to lean. This tree is about 8 feet tall now, and the shoots from the base are about 5 feet tall. I don't think these trees were grafted, so I don't think the shoot would be a root stock of a different variety.
Should I cut down the main leader and let the root shoot that is nice and straight become the main leader of the tree? I've never had a tree throw up shoots like this before so I'm not sure if I need to do anything at all...
Thanks in advance
