Unbalanced Crown The growth of trees in forest conditions usually results in them having long, straight, trunks. However, open grown urban trees develop wider crowns with lower branching. They often have irregular or unbalanced crowns because of past damage, management practices, restricted growing space, conflict with buildings, or a lack of light. This can result in structural weakness and hazard problems. If the tree crown is unbalanced, lopsided, or developed as a flag, the tree would have an unbalanced crown. A tree might have an unbalanced crown but straight trunk or it can have both an unbalanced crown and a leaning stem. Three classes are established for unbalanced crown. 0 There are no signs that the crown is unbalanced or lopsided; crown normally developed. 1 Crown slightly asymmetrical due to restricted growing space or lack of light. 2 Crown is asymmetrical, unbalanced or lopsided. 3 Crown is severely asymmetrical to the point where it clearly places damaging stress on the main stem or root system.
