The Science: Deadwooding goes beyond simple aesthetics; it is crucial for disease prevention and hazard mitigation. When a branch dies, it becomes a prime entry point for saprophytic fungi and wood-decaying pathogens. By expertly removing this necrotic tissue back to the branch collar — without damaging the living cambium layer — we allow the tree to properly compartmentalize the area. This prevents decay from traveling into the heartwood of the main trunk while instantly eliminating the mechanical risk of dead branches failing during high Treasure Valley winds or winter snow loads.
The Science: Pollarding is an ancient, highly technical pruning method used to manage tree size in confined urban spaces. By initiating cuts on young trees and routinely removing the annual shoots during the dormant season, we force the tree to develop swollen areas of callus tissue known as ‘pollard heads’ or ‘knuckles.’ This process manipulates the tree’s natural hormones (auxins and cytokinins), stimulating a dense flush of vigorous, adventitious growth each spring. When performed correctly, pollarding maintains a healthy balance between the root system and the canopy, preventing root expansion from damaging nearby infrastructure while keeping the tree at a safe, predetermined size.
