The O₂Tree shaped trees are very versatile. Where roof trees are often used to create shade, espaliers are usually used planted to provide privacy. Block trees, on the other hand, are often used as an ornamental element. Consider, for example, the beautiful flaking bark of a plane tree. Or evergreen guided trees with which you can make a beautiful green wall.
Whatever purpose you have in mind with your shape tree, they will fit almost any garden. The growth habit is framed by the frame that is used. With a roof tree, this is a star-shaped frame made of bamboo sticks. With a espalier this is a bamboo rack of 120 or 150cm wide and 150cm high. The difference in width depends on the type of tree. O₂Tree also has block trees with an iron frame in its range.
Shaped trees are easy to maintain. You can prune a shape tree annually to ensure that it does not grow too large. You can safely cut off protrusions. Instructions on watering, fertilization, location and pruning can be found on this website.
