Crown reduction revisited…

Carrying out a sympathetic crown reduction on a large broadleaf tree is something that gives an arborist immense satisfaction. On revisiting the property of a long standing customer to discuss further tree works, I had the pleasure of seeing the results of a pruning task carried out two years ago on a very large mature beech tree. The original specification was to perform a 2 metre full crown reduction to enhance the natural beauty of the tree and to allow more sunlight to reach the garden. The pleasing part was to see that the tree had responded so well to pruning and that it was full of vigour.

Trees, especially beech struggle to cope with hard pruning, which in effect is removing material so key to its existence. Cutting branches (containing stored energy) and leaves (photosynthetic material) impacts on the trees ability to photosynthesize and produce energy; but also removes existing stores crucial for root development and branch and leaf formation. This has a dramatic effect on tree health, not only because of the reduced energy production but also the potential for colonization from pathogens via exposed pruning wounds. The culprits, wood decay fungi or bacterial infections, leading to future decay or even failure. To mitigate against the potential for damaging a tree through pruning, we ensure that all our work is carried out to industry best practice (British standard BS 3998: 2010) and apply knowledge learned through years of experience and extensive study.
