What Are The Signs A Branch Has Actually Died?
Look for three things together: wood that stays bare while the rest of the crown leafs out normally, bark that peels away with light pressure instead of gripping tight, and a dry, pale colour underneath rather than the moist look of live tissue. Describe what you're seeing and we can often make a good guess before we even arrive.
Can Construction Nearby Cause Branches To Die Off?
Yes, and it's a common pattern. Root damage or soil compaction from digging can starve a section of the crown of water and nutrients well before the whole tree shows obvious signs of stress, so isolated dead branches sometimes show up first.
How Dangerous Is A Dead Branch, Really?
More than the word "unsightly" suggests. A living branch bends with wind and load; a dead one has no give left, so it simply lets go, often unpredictably. On a property with contractors, deliveries or a work crew coming and going, that unpredictability is worth taking seriously.
