Most trees that come down were showing signs beforehand. Here is what to look for, roughly in order of how seriously to take it.
1. Fungus at the base
Shelf fungus, brackets or clusters of mushrooms around the root flare mean fungi are consuming wood in the part of the tree carrying all the load. The outside can look perfectly healthy while the inside is gone. This is the sign most often missed and most worth acting on.
2. A lean that is new, or soil lifting
Plenty of trees lean and have leaned their whole lives. What matters is change. A lean that appeared recently, cracked soil or a raised mound on the side opposite the lean, and exposed roots on the low side all suggest the root plate is moving.
3. Cracks and splits in the trunk
A vertical crack, a seam running down from a fork, or two halves that have visibly separated means the trunk is no longer working as one piece. Splits do not heal.
4. Deadwood in the upper canopy
Bare branches at the top while the lower canopy leafs out points to trouble in the roots or the vascular system. Dying from the top down is worse news than losing a few lower limbs.
5. Cavities and old wounds
Hollows matter in proportion to how much sound wood is left around them, and where they sit. A cavity low on the trunk is far more serious than one in a limb.
6. Root damage from digging
Trenching for a driveway, utility line, patio or new garage cuts roots the tree depends on for stability. Decline often shows up a year or two later, and the tree can stand there looking fine in the meantime. If something was dug near a big tree recently, watch it closely.
7. Leaves dropping from the outside in
When the outer canopy sheds first and dieback works inward toward the trunk, the root system is failing to supply the crown.
How urgent is it?
Weigh each sign against what sits underneath. A hollow tree at the back of five acres can often be left for wildlife. The same tree over a bedroom, a driveway or a neighbor’s garage is a different conversation. If you are unsure, get it looked at before the next storm rather than after.
Common Questions
Is a hollow tree always dangerous?
Not always. What matters is how much sound wood remains around the cavity and what sits underneath. A hollow trunk near a house is a different matter from one at the back of a field.
My tree leans. Should I worry?
A lean it has always had is usually fine. A new lean, cracked or heaving soil on the opposite side, or roots lifting on the low side all mean the root plate is moving.
How quickly should a dead tree come down?
Sooner if it is within falling distance of a house, driveway, road or fence. Dead ash in particular becomes brittle quickly and is worth prioritizing.
