Plant Diseases/Blue spruce in danger of falling?
We have a blue spruce of about 50 ft height. The lowest 10-12 ft are straight but somewhat leaning to one side. Next, the tree grows in an S-shape for about 25 ft, and then come another 10-15 ft of straight growth, although split (from ice-storm damage). The top part of the trunk is about 6 ft offset from the lowest part of the trunk. It seems to us that this "leaning over" has gotten worse over the years. How likely is the tree to fall over or break apart? There is a wonderful cherry-tree, a play-structure, and a fence that would potentially be damaged.
Looks as if the tree has compensated for the lean and the upper half is growing straight. I would check the ground away from the side of the lean and if the ground is being uplifted then there is a problem. But if the ground is not being uplifted the root system has also compensated and I would not think there is any danger of the tree falling. I would fertilize the tree with 10-10-10- fertilizer at the rate of 1 lb. per inch of trunk diameter scattered around the tree and watered in good. Apply the fertilizer just before a rain storm and you will not need to water. This will increase the root health and make the roots stronger and hold better. Beyond that I think the tree will be there for a long time.
