True pollarding is initiated when a tree is very young, soon after it has been established. Once initiated, we advise that a pollard should be maintained by cutting the new branches on a cyclical basis.
Lapsed Pollards are trees that were once heavily pruned and have regrown over many years. We follow advise laid out in the BS3998 to manage such trees. Gorey common is an example of where Jonathan Le Maistre Tree Surgery Ltd have implemented correct pruning methods to save trees which would otherwise have been eventually condemned.
We use crown reduction to alleviate biomechanical stress by reducing both the leverage and the sail area of the tree. This can allow the retention of a tree in a confined space. It can also be used to reduce interference with adjacent structures, create a desired appearance or to make the tree more suited to its surroundings. Not all species or individual trees are appropriate candidates for reduction. In crown re-shaping, we selectively reduce the height and/or spread of one or more portions of the crown to bring the tree back into balance.
It is generally undesirable to wound trees so severely that major dieback or extensive decay are likely to ensue. Accordingly, we advise severe crown reduction as a last resort for retaining a valuable tree which would otherwise pose an unacceptable risk to people or property or would be susceptible to loss due to structural collapse. Gorey common is an example of where Jonathan Le Maistre Tree Surgery Ltd employed this method to save trees which would otherwise have been eventually condemned.
