Pruning an apple tree involves not only pruning branches and foliage, but also thinning out the fruit. Proper pruning of any fruit tree is essential to producing a strong enough frame to bear plentiful fruit.
It is important to note that apple trees will often produce more fruit than the branches can support, and the excess must be removed manually to prevent broken limbs.
Apple tree care also involves pruning of the branches. This should take place during the winter, while the tree is dormant.
Pruning during dormancy will invigorate the tree into growing more the following season. Once the tree has reached the desired size, pruning during the summer will help to prevent future growth.
Information about apple tree care can be found from several sources.
One good place to start looking for apple tree care information is at a local nursery or garden center. Using search engines such as Google will result in some good information as well.
Libraries will often carry books pertaining directly to apple tree care. Whatever the source of information, ensure that it is reliable before following any directions.
