Choosing a tree with a more desirable form is the most effective way to preemptively avoid issues associated with aggressive, upright branching. When selecting trees for urban areas or residential landscaping, it is crucial to consider their natural growth habit and branching structure. Some tree species have a more harmonious or spreading form that results in branches that grow outward rather than upward, reducing the potential for overcrowding, the need for extensive pruning, or issues with proximity to structures or utility lines.

Opting for a species known for its aesthetic appeal and compatible growth pattern aligns with the landscape design objectives while mitigating maintenance challenges. This proactive approach can lead to healthier trees and more sustainable urban forestry practices.

In contrast, while adjusting pruning techniques can help manage aggressive branches after they've formed, it does not eliminate the underlying issue of selecting inappropriate tree species for the location and intended design. Similarly, using growth inhibitors may mitigate growth to some extent, but this can also lead to health issues in the tree and does not address the root cause of the problem. Increasing watering and fertilization may promote more vigorous growth, which could exacerbate the issue of upright branching rather than solving it. Therefore, selecting a tree with a proper form is the most effective strategy for avoiding future complications.
