The best time to trim and prune plants and trees is when they are fully dormant in late Winter, so August is the best month! Here are a few tips and techniques to follow to give your trees the best chance for spring.
1. Most plants need a certain amount of light to produce new growth, flowers or fruit. By crown- thinning, reduction or lifting of trees light can reach plants under trees and will create favorable growing conditions for gardening under trees. There will be better airflow after thinning, reduction or lifting which will reduce moisture build-up in soil in wet conditions. More light will also reduce the risk of certain diseases attacking plants in shady, damp conditions.
2. The best time to prune and trim trees is in July and August for most trees. Because deciduous trees are empty by then and evergreens are a lot thinner in winter it enables the tree felling professional to see better which branches to remove or thin when cutting is done. Pruning and trimming can be done throughout the year, but remember that by cutting flowering trees just before flowering, the flowering time will only be in the following season as flower bearing stems may be removed when cutting is done. Winter gardens are mostly devoid of lush growth and flowers and with the activity of cutting there will be less damage to foliage and precious flowers.
3. Crown-thinning refers to the thinning out of the crown of trees where certain branches are removed to let dappled light reach the surrounding areas under trees. On average about 25 % more light can be let into these areas.
4. Reduction refers to the removal of long branches in a tree or to shape trees. By reducing the length of branches more light can be brought to under the trees. Some gardeners are eager to “top” the tree lower. This usually results in a lot of lateral growth forming and in the end there will be denser growth and more shade. The professional tree feller will usually cut only to a fork or to against the stem. He will also take into account the shape and balance of the tree when cutting.
5. Lifting refers to lifting or crown lifting of lower branches growing too close to the surface. By removing such branches, light or even direct sunlight can be brought into previous shady spots. Your professional tree feller will again take into account the shape and balance of the tree. Crown lifting leaves the tree with a narrower profile and works well where a lot of mature trees are planted close together. By lifting them, previously dark, moist areas can be rejuvenated with the extra light brought in.
