There are many reasons to cut trees. It is best to remove the diseased branches to stop the growth of the disease and to remove parts of the tree that are not too attractive. Or say a destructive storm has caused part of the branch to break and dangle; trees will be much happier with these branches removed.
Maybe a tree needs a crown that is cut so that air circulation is better so that healthy new growth will begin to emerge. A tree also needs to be pruned when the lower branches block the road, the view or lower shrub growth.
Maybe you want to train trees to grow in a certain direction for design purposes, so pruning can be a consideration. And there is always a reason to reduce the height of the tree because the tree grows too high. North Shore Tree Pruning, Trimming & Removal Services in Sydney offers a variety of great trimming tips and pruning techniques that can help keep your trees in excellent shape.
It is best to prune during the inactive season in late fall or winter. However, dead branches can and must be removed at any time. Pruning during periods of inactivity minimizes the loss of sap and subsequently, pressure on the tree.
Because fungal infections and/or insect attacks are also inactive during this time, pruning the tree then minimizes the risk of damage that attacks the tree. Also, in the case of deciduous trees, pruning when the leaves die will allow you to design your cuts with the overall shape of the tree structure.
After you decide which tree to cut, then determine whether you can do it yourself or need to recruit experts. If the tree is tall and involves large branches especially near the top, then there should be no questions.
