Topping, the practice of cutting back large branches to stubs, should be avoided as it can cause significant harm to trees. This method creates weak, rapidly growing branches that are more susceptible to breaking and disease. Topping also removes a large portion of the tree's foliage, reducing its ability to produce energy through photosynthesis. The resulting stress can lead to decay and even tree death. Instead of topping, opt for proper pruning techniques like crown reduction or thinning, which maintain the tree's health, structure, and natural appearance. Consult a professional ISA Certified Arborist for safe and effective pruning methods.
