Not every tree risk is obvious from the ground. Codominant stems, two trunks of similar size growing from the same point, are one of the most common structural weaknesses homeowners never notice until it is too late.
Instead of one trunk with a strong branch attachment, codominant stems often form a weak, included bark union that can split apart under wind load, ice, or simply the tree's own weight as it matures. Over time, that weak union accumulates stress with every growing season, making early identification the single best defense against a sudden failure.
The risk is highest in fast-growing species common across Tri-County PA, and a split codominant stem can mean the loss of half a mature tree with little warning. A trained eye can spot the warning signs well before failure happens.
If a tree on your property has two trunks growing close together, it is worth having someone knowledgeable take a look. Free estimates available throughout Montgomery, Chester, and Delaware counties. #TreeStructure #TreeHealth #TriCountyPA #ArboristTips #DelawareCountyPA
