Different species of trees should be trimmed at different times. Trees that flower in spring should be trimmed when their flowers fade. Shrubs and trees that bloom in the middle or end of summer should be pruned in early spring or winter.
The most common practice of trimming is during winter which results in an enthusiastic new growth at springtime. It is good to wait until the coldest part of winter has passed for trimming. Some plant species like birch, walnut and maple may bleed. The sap will flow and stop when the leaves come out. To shorten the development of a branch or tree trimming should be done after the completion of seasonal growth.
Why should a tree be trimmed?
A tree should be trimmed to enhance its looks. When you trim you remove special stems and branches it will help the tree to grow better. The health of the tree can be improved by removing dead and damaged branches and preventing decay organisms and insects from entering the tree. If a tree has a dense canopy thin it out to allow sunlight and air to enter and reduce disease problems. Do away with crossing branches to prevent damage by rubbing against each other. Get rid of water sprouts and suckers to eliminate wood that is weak and provides water and food for another part of the tree.
Pruning flowering trees to improve flowering
If you want to prune trees to improve flowering then you should prune when the flowers dwindle. Shrubs and trees that flower in late summer should be pruned in early spring or winter. When trees are trimmed in winter insects and fungus cannot affect the wounds and they will heal nicely.
Fall is not the right time to prune any plants because fungi and decay spread their spores during this time. Wounds of trees take a long time to heal during fall and can easily get infected.
When to trim Shrubs and Trees?
The best time to trim shrubs and trees is during winter months when they are dormant. During these times there is less risk of pest and disease infestation. The wounds heal quickly and the plant remains strong. There is less sap oozing, so it can be less messy and will not attract insects. In winter when leaves are not there you can see what you are doing.
There are guidelines for pruning different trees. Shrubs and trees that bloom in the summer should be pruned in winter. Conifers can be trimmed towards the end of winter when they are dormant. Trees and shrubs that do not bloom should be trimmed in the later part of winter when they are dormant. Trees and shrubs that bloom in spring should be pruned after their bloom is over.
Removal of dead and damaged branches
Small tree branches which are dead or damaged can be trimmed any time with handheld shears. Hedges and conifers can also be shaped at any time. If you are living in a place that is prone to ice storms and hurricanes then you should remove weakened branches in the fall.
Different species of trees should be trimmed at different times of the year. Most of the trees are trimmed in winter when they are dormant.
