Leaning TreeThis tree has a "severe" lean. When it falls, it will probably split the house in two.
Dying TreesNotice how thin the leaves are at the top of the front trees, while all the other trees have a full canopy of leaves. There may be clues at the base of the trees that tell you why they are dying.
Dead TreesWhen all the leaves turn brown during the growing season, the tree is dead.
Tree too close to houseThe limited area for roots and for trunk growth can create problems for the tree and the house.
Lightning strikes a big treeSometimes lightning kills a tree, but not always. Wait about six weeks to see if the leaves start to turn brown. If they do, your tree is a "goner." If the leaves stay green, have the tree checked carefully for structural damage.
Two pine treesWhich tree is dead? The one on the left does not have green needles. It is dead.
Dead top in oak treeA tree has a serious problem when it starts to die from the top down. Have it checked out immediately.
Zone 1: The tree as a whole
From a place where you can see the whole tree at one time, take a long look. Focus on the entire tree rather than its individual parts.
- Is the tree leaning? What is it leaning toward (the "target")? Has this lean been there for a long time? Is it leaning more than it was a day, week, or month ago? Is the tree leaning in an easterly direction? Trees that lean toward the east are more vulnerable to falling because most of the winds come from the west.
- Can you see any big dead branches? Are there a lot of dead branches, or just a few? Are they on the lower part of the tree, or only on one side of the tree?
- Are there sections of the tree where there are no leaves at all? Does the tree have a thin leaf cover? Are the leaves dropping much earlier than from other trees of the same species nearby? Do the fallen leaves look unusual?
- Are the branches dying back at the tips?
If the answer is “yes” to any of these questions, your tree may be in the process of falling over, sick, imbalanced, or dying. Get the tree evaluated immediately by a Certified Arborist. Better to be safe than sorry.
