Not sure their age or origin. Please ask any questions you might have. Tree #1 67 tall 48 diameter at widest part. Tree #2 61 by 32 diameter. Tree # 3 56 x 78diameter at base and 38 around top. These trees are very heavy. I estimate that they weigh between 400-600 lbs. Four men could not lift them. You will need a forklift or backhoe to move and lift them. I cannot help with the lifting. They are located in my front yard. We have taken the, out of the concrete wall and yard and they are laying together on the ground.
