One of the most important subjects when planting trees is staking and tying. In the first growing season or two, trees need adequate support to allow successful establishment.
For an average standard tree of around eight to ten feet in height a round pointed tree stake about 1.8m tall and two to three inches thick, will give enough support to stop excessive root and stem movement. A little movement is desirable as this will stimulate root growth to enable the tree to be independent in a couple of years.
A buckle type tree tie with a spacer incorporated between the stake and the stem of the tree is the industry standard. These sort of ties are adjustable so that stem expansion can be accommodated . It is important that the tree tie is nailed or stapled to the stake to stop any twisting in windy weather.
