I'm hoping for some insight into these trees. We have one in our garden, it has been there at least 20 years (it was there when we bought the house). I've only just found out what it is and how big they get! Everything I've read says they are very slow growing but that they tend to live in wetlands. My garden is definitely not a wetland!
I'm hoping to get an idea how long they take to mature and what to do to keep it healthy.
