The short answer: a tree in Princeton is dangerous when the trunk is cracked or splitting, more than about a third of the canopy is dead, mushrooms or conks are growing at the base, roots are lifting or torn, or the lean has gotten worse over time. Any one of these warrants an on-site evaluation. Two or more usually mean removal.
Princeton and the surrounding Collin County towns have a mix of mature post oaks, cedar elms, pecans, and 1990s-era Bradford pears. Each species fails in a slightly different way, but the warning signs below apply to all of them. A tree standing today is not proof the tree is safe; hazard trees usually give notice before they fall, and homeowners who catch the signs early save their house, their car, and sometimes their neighbor's roof.
1. A lean that is getting worse. Some trees have always leaned; that alone is not a red flag. The dangerous case is a tree that used to stand straight and is now tilting, especially if you see fresh soil disturbance or lifted roots on the uphill side. That is the root plate failing. Once the root plate goes, the tree comes over in the next thunderstorm.
2. Large dead branches, especially over the roof. Deadwood does not heal. In a North Texas storm with 60 mph gusts, dead limbs break and drop. If more than about a third of the canopy is dead, the whole tree is usually past saving. A single large dead limb over a bedroom is enough reason to remove it before the next round of weather.
3. Mushrooms or shelf-like conks at the base. Fungal fruiting bodies on the trunk, the buttress roots, or the soil right at the base of the tree mean there is internal rot. Armillaria, Ganoderma, and Inonotus are common in this part of Collin County, and by the time the mushrooms appear the wood inside is already turning to sponge. A tree with significant heart rot cannot support its own weight in high winds.
4. Cracks or splits in the trunk. Vertical cracks running down the main trunk, especially cracks that open and close in the wind, mean structural failure is already in progress. Bradford pears are famous for this because of their weak branch unions; they split down the middle in April and May storms every year in Princeton, Anna, and Melissa neighborhoods. A cracked trunk near a house is a removal, not a repair.
5. Root damage or exposed, torn roots. Construction next door, a trench for a new fence, a driveway pour that clipped the drip line, or erosion on a sloped lot can all sever structural roots. The tree may look fine above ground for a year or two, then fail all at once. If you know roots were cut, get the tree looked at before the next storm season.
6. Hollow areas or cavities you can see or hear. Tap the trunk with a rubber mallet or the back of a hatchet. Solid wood sounds solid. Hollow wood sounds like a drum. A cavity by itself is not automatically a removal because trees can compartmentalize decay, but a large hollow low on the trunk combined with any other warning sign is a removal.
What to do next: do not try to prune your way out of a structural problem. Topping a dying tree or lion-tailing a leaner does not fix it and often accelerates failure. Get a written evaluation from an insured pro. If the tree is a candidate for saving, that will be spelled out with a specific pruning plan. If it is not, removal will be scoped in writing, and you can bundle in stump grinding on the same visit.
