Moving a very mature Meyer lemon
We have a very mature, age unknown (how do you ID age of lemon tree? that's a separate question) Meyer lemon tree in the garden that needs to be moved 3 feet left to make room for a patio door. The tree has been around and mature since we moved in 7 years ago, and it's about 7 feet tall and extremely productive - hundreds of lemons almost year around. It is west facing.
Can we move it without killing it? What is the expected lifespan of a lemon tree? We are considering the cost of moving it (not sure if this is something we can do ourselves without killing it) vs planting a new one. Here's a picture:
